DETAILED DESCRIPTION

The following detailed description is merely illustrative and is not intended to limit embodiments and/or application or uses of embodiments. Furthermore, there is no intention to be bound by any expressed or implied information presented in the preceding Background or Summary sections, or in the Detailed Description section.


One or more embodiments are now described with reference to the drawings, wherein like referenced numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a more thorough understanding of the one or more embodiments. It is evident, however, in various cases, that the one or more embodiments can be practiced without these specific details. Additionally, it is to be understood that various types of shading and/or cross-hatching presented within the drawings can delineate like features, like materials, and/or like compositions.


Traditional biosensors comprise one or more sensor devices located on a rigid semiconductor substrate. Typically, the biosensors are implanted into a host by plunging the biosensor directly into the host's tissue. The biosensors can detect various characteristics of the surrounding tissue and stimulate the tissue via various devices (e.g., via light emitting diodes (“LEDs”)). However, plunging the biosensor into the host tissue can cause undesirable damage to the tissue. Further, the rigidity of traditional biosensors limits possible implant locations within the host. Also, traditional biosensor structures leave various components (e.g., the semiconductor substrate) unprotected from biological defense mechanisms, which can cause deterioration to the biosensor by the host. In addition, substantial direct exposure of various components (e.g., LEDs) to the host tissue can necessitate performance limitations (e.g., limitations on power usage to avoid overheating the tissue surround the biosensor).


Various embodiments described herein can regard an implantable package that can comprise one or more sensor modules embedded within a protective polymer. The one or more sensor modules can monitor and/or manipulate surrounding tissue while the polymer protects the one or more sensor modules from the hosts biological defense mechanisms and/or biological environment. Further, the polymer can be elastomeric, thereby providing flexibility to the implantable package. Due at least in part to the protective and flexible properties of the polymer, the one or more sensor modules can be manufactured using known electrical engineering techniques to achieve dimensions smaller than typical, bulky biosensors. In one or more embodiments, the implantable package can comprise a plurality of sensor modules to provide redundancies in case of mechanical failure and/or facilitate multiple functions. Moreover, in one or more embodiments the implantable package can further comprise one or more chemical delivery systems that can facilitate distribution of one or more chemicals to surrounding tissue.



FIG. 1 illustrates a diagram of an example, non-limiting biosensor package 100 from a cross-sectional viewpoint in accordance with one or more embodiments described herein. The biosensor package 100 can comprise a polymer layer 102, one or more biosensor modules 104 (e.g., indicated with a dashed line in FIG. 1), and/or one or more chemical delivery systems 106. The biosensor package 100 can be implanted into a biological environment, such as onto and/or into tissue (e.g., tissue of a host entity).


The polymer layer 102 can comprise a bioinert elastomeric polymer and can be provided on a plurality of sides of the one or more biosensor modules 104. For example, the polymer layer 102 can comprise one or more wall portions extending (e.g., in the “Y” direction) substantially perpendicular to a base portion (e.g., extending in the “X” direction), wherein the one or more biosensor module 104 can be located on top of the base portion and/or between the wall portions. For instance, as shown in FIG. 1, the polymer layer 102 can be provided on a left side, a right side, and a bottom side of the one or more biosensor modules 104. In one or more embodiments, the polymer layer 102 can surround the one or more biosensor modules 104. Also, in one or more embodiments the polymer layer 102 can encapsulate the one or more biosensor modules 104 (e.g., the polymer layer 102 can be further located on the top side of the one or more biosensor modules 104).


One of ordinary skill in the art will recognize that the dimensions of the polymer layer 102 can vary depending on the desired functions of the biosensor package 100, the type of polymer comprising the polymer layer 102, the biological environment the biosensor package 100 is expected to be implanted within, a combination thereof, and/or like. For example, a length of the polymer layer 102 (e.g., along the “X” direction) can range from, but is not limited to, greater than or equal to 5 micrometers (μm) to less than or equal to 180 μm. In another example, the height of the polymer layer 102 (e.g., along the “Y” direction) can range from, but is not limited to, greater than or equal to 1 millimeter (mm) and less than or equal to 2 mm. In a further example, the respective length (e.g., along the “X” direction) of the polymer layer's 102 one or more wall portions can range from, but is not limited to, greater than or equal to 30 μm and less than or equal to 1000 μm. In an additional example, the thickness of the polymer layer 102 can range from, but is not limited to, greater than or equal to 0.3 millimeters (mm) and less than or equal to 10 mm.


The polymer layer 102 can be characterized as being elastomeric, durable, bioinert, resistant to corrosion, an insulator, a combination thereof, and/or the like. Example polymers that can comprise the polymer layer 102 include, but are not limited to: polydimethylsiloxane (“PDMS”), polyurethane, chitin and/or similar bio-derived polymers, cellulose materials, a combination thereof, and/or the like. Also, the polymer layer 102 can be embedded with stable bio molecules (e.g., glycoproteins and/or myelin) so as to provide camouflage against biological defense mechanisms (e.g., immune systems). Further, in one or more embodiments, the polymer layer 102 can comprise tabs and/or protrusions that can be utilized to fix the biosensor package 100 to subject tissue.


The one or more biosensor modules 104 can be embedded within and/or fixed to the polymer layer 102. Further, the one or more biosensor modules 104 can comprise one or more sensors 108, one or more semiconductor substrates 110, one or more stimulus devices 112, one or more computer units 114, and/or one or more power devices 116.


The one or more sensors 108 can detect and/or monitor one or more conditions of the tissue and/or environment surrounding the biosensor package 100. The one or more detected and/or monitored conditions can regard, for example, one or more chemical and/or physical properties of the surrounding tissue and/or environment. Example conditions that can be detected and/or monitored by the one or more sensors 108 can include, but are not limited to: temperature, moisture content, pressure, light absorbance, electrical conductance, chemical species or biological information transmitters such as neurotransmitters, hormones, growth factors, metal ions such as Calcium, sodium and potassium, and pH, a combination thereof, and/or the like. Example devices that can comprise the one or more sensors 108 can include, but are not limited to: thermometers, piezoelectric materials, light sensors, pressure sensors, electrodes, chemical sensors such as electrodes sensitized to specific molecules, using fast scan cyclic voltammetry, field-effect transistor (“FET”) sensors, bipolar junction transistor (“BJT”) sensors, conductive organic electrodes imprinted with the target molecules, organic electrochemical transistor (“OECT”) devices, fluorescence detectors, a combination thereof, and/or like. In one or more embodiments, the one or more sensors 108 can be optimized to monitor specific biomolecules. For example, one or more electrodes comprising the one or more sensors 108 can be coated with various polymers, which can be sensitive to respective biomolecules (e.g., such as polypyrrole, polyaniline, poly(3,4-ethylenedioxythiophene) (“PEDOT”), functionalized derivatives of PEDOT (e.g., methoxy, amine, alcohol, alkyl derivatives), imprinted with the target molecules, and/or glassy carbon for use with fast scan cyclic voltametry).


In one or more embodiments, the one or more sensors 108 can be fixed to the one or more semiconductor substrates 110. Additionally, in one or more embodiments, the one or more sensors 108 can interact with the one or more semiconductor substrates 110 through one or more vias 118. Further, the one or more sensors 108 can be positioned at various pitches ranging from, for example, greater than or equal to 300 nanometers (nm) and less than or equal to 1000 nm. Additionally, respective biosensor modules 104 can comprise various types of sensors 108. In other words, the one or more sensors 108 of a biosensor module 104 are not limited to a single type of device, nor are the functions of the one or more sensors 108 limited to a single function (e.g., detecting and/or monitoring a single type of condition).


The one or more semiconductor substrates 110 can support one or more features (e.g., the one or more sensors 108, the one or more stimulus devices 112, and/or the one or more computer units 114) of the one or more biosensor modules 104. Example materials that can comprise the one or more semiconductor substrates 110 can include, but are not limited to: silicon, germanium, silicon carbide, carbon doped silicon, compound semiconductors (e.g., comprising elements from periodic table groups III, IV, and/or V), silicon oxide, a combination thereof, and/or the like. For instance, the one or more semiconductor substrates 110 can be a bulk silicon wafer and/or a silicon-on-insulator (“SOI”) wafer. Additionally, the one or more semiconductor substrates 110 can comprise electronic structures such as isolation wires (not shown). Further, the one or more semiconductor substrates 110 can be characterized by one or more crystalline structures. For example, the one or more semiconductor substrates 110 can comprise silicon <100>, silicon <110>, and/or silicon <111>, as described using Miller indices. Additionally, in one or more embodiments the one or more semiconductor substrates 110 can be transparent and/or semi-transparent to facilitate operation of the one or more sensors 108 and/or the one or more stimulus devices 112. For instance, in one or more embodiments the one or more semiconductor substrates 110 can comprise silicon oxide. In another instance, in one or more embodiments the one or more semiconductor substrates 110 can comprise gallium nitride. Moreover, in one or more embodiments the semiconductor substrate 110 can comprise semiconductor minerals and/or gemstones, such as sapphire. One of ordinary skill in the art will readily recognize that the thickness of the one or more semiconductor substrates 110 can vary depending on: the composition of the one or more semiconductor substrates 110, the number of sensors 108, the number of stimulus devices 112, the desired function of the biosensor package 100, a combination thereof, and/or the like.


The one or more stimulus devices 112 can generate one or more forms of stimulus to manipulate and/or modify the tissue and/or environment surrounding the biosensor package 100. For example, the one or more stimulus devices 112 can stimulate (e.g., and thereby manipulate and/or modify) the tissue and/or environment surrounding the biosensor package 100 with electrical signals, vibrations, heat, light, a combination thereof, and/or like. Example stimulus devices 112 can include, but are not limited to: LEDs, piezoelectric devices (e.g., lead zirconate titanate (“PZT”) devices), electrodes, magnetic inductors, optical fibers, pulsed electrodes, physical nanorods and/or tubes for piercing cell structures, a combination thereof, and/or the like. Additionally, respective biosensor modules 104 can comprise various types of stimulus devices 112. In other words, the one or more stimulus devices 112 of a biosensor module 104 are not limited to a single type of device, nor are the functions of the one or more stimulus devices 112 limited to a single function (e.g., emitting light). In one or more embodiments, the one or more stimulus devices 112 can comprise one or more LEDs that can, collectively, emit light of various frequencies. For instance, one or more of the LEDs of the biosensor module 104 can emit blue light and/or one or more other LEDs of the biosensor module 104 can emit red light.


In various embodiments, the one or more stimulus devices 112 can be integrated within the one or more semiconductor substrates 110. The one or more semiconductor substrates 110 can provide mechanical support to the one or more stimulus devices 112 and/or can facilitate one or more electrical connections between the one or more stimulus devices 112 and/or the one or more computer units 114. For example, the one or more semiconductor substrates 110 can comprise conductive material (e.g., conductive strips, transmission lines, nanowires, electrical wires, a combination thereof, and/or like) to facilitate operable coupling of various features (e.g., the one or more sensors 108, the one or more stimulus devices 112, the one or more computer units 114, and/or the one or more power devices 116). Further, the one or more vias 118 can also facilitate said operably couplings.


The one or more computer units 114 can comprise, for example, one or more processors to facilitate execution of one or more computer readable program instructions. Example computer units 114 can include, but are not limited to: microcontrollers, microprocessors, microcomputers, field-programmable gate arrays (“FPGA”), a combination thereof, and/or the like. The one or more computer units 114 can analyze data collected by the one or more sensors 108 and/or control the one or more stimulus devices 112 based on the analysis to achieve one or more objectives. The one or more computer units 114 can be operably coupled to the one or more sensors 108 and/or the one or more stimulus devices 112. For example, the one or more computer units 114 can be operably coupled to the one or more sensors 108 and/or the one or more stimulus devices 112 via one or more electrical connections (e.g., wires) and/or one or more vias 118 comprised within the semiconductor substrate 110. One of ordinary skill in the art will recognize that the dimensions of the one or more computer units 114 can vary depending on the desired functionality of the biosensor package 100. For example, the one or more computer units 114 can be comprised on a die size ranging from, but not limited to, greater than or equal to 100×100 μm and less than or equal to 1000×1000 μm.


The one or more power devices 116 can supply power (e.g., electricity) to the one or more sensors 108, the one or more stimulus devices 112, and/or the one or more computer units 114. Also, the one or more power devices 116 can be operably coupled (e.g., via one or more vias 118) to the one or more sensors 108, the one or more stimulus devices 112, and/or the one or more computer units 114. The one or more power devices 116 can comprise, for example, one or more capacitors and/or one or more batteries. In one or more embodiments, the one or more power devices 116 can be charged and/or re-charged wireless, for example, through the use of one or more inductors. Thus, the one or more power devices 116 can be charged and/or re-charged while implanted within the host.


The one or more chemical delivery systems 106 can be comprised within one or more wall portions of the polymer layer 102. The one or more chemical delivery systems 106 can comprise, for example, one or more microfluidic channels that can be loaded with one or more hydrogels (not shown). FIG. 1 illustrates chemical delivery systems 106 comprising microfluidic channels extending along the “Y” direction in straight paths; however, the architecture of the microfluidic channels is not so limited. For examples, the microfluidic channels can be characterized by various path architectures such as diagonal paths, zig-zag paths, and/or U-shaped paths. In one or more embodiments, a distal end of the one or more microfluidic channels comprising the chemical delivery systems 106 can be exposed to the tissue and/or environment surrounding the biosensor package 100. Thus, the polymer layer 102 can define a plurality of sides of the one or more chemical delivery systems 106 while leaving one or more sides of the chemical delivery systems 106 open to the surrounding tissue and/or environment.


As shown in FIG. 1, the one or more chemical delivery systems 106 can be located adjacent to the one or more biosensor modules 104. For example, the one or more chemical delivery systems 106 can flank one, two, three, and/or four sides of the one or more biosensor modules 104. One of ordinary skill in the art will recognize that the dimensions of the one or more chemical delivery systems 106 can vary depending on the desired volume of hydrogel to be loaded within the microfluidic channels. For example, the respective widths of the one or more microfluidic channels that can comprise the chemical delivery systems 106 can range from, but are not limited to, greater than or equal to 5 μm to less than or equal to 180 μm. The one or more chemical delivery systems 106 can be characterized by uniform dimensions; or alternatively, can be characterized by varying respective dimensions.


In one or more embodiments, the one or more chemical delivery systems 106 can be loaded with one or more hydrogels. The one or more hydrogels can comprise one or more chemical compounds to be distributed to the tissue and/or environment surrounding the biosensor package 100. For example, the hydrogels can react (e.g., dissolve and/or otherwise degrade) in the presence of the surrounding tissue and/or environment (e.g., due at least to one or more biological defense mechanisms of the host), and thereby released the one or more subject chemicals comprised within the hydrogel. Thus, the one or more subject chemicals can escape from the one or more chemical distribution systems 106 (e.g., via the one or more exposed sides) and/or interact with the surrounding tissue and/or environment. Further, respective chemical delivery systems 106 can house the same chemical compounds and/or respective chemical delivery systems 106 can comprise respective chemical compounds. Example chemical compounds that be comprised within the hydrogel and/or housed within the one or more chemical delivery systems 106 can include, but are not limited to: a genetic material (e.g., carried by a virus) for expression of a protein, a neural transmitter (e.g., dopamine, gamma-Aminobutyric acid (“GABA”), and/or serotonin), a growth factor, a growth inhibitor, a medicine (e.g., a medication for epilepsy and/or Parkinson's disease), a combination thereof, and/or the like.



FIG. 2 illustrates a diagram of the example, non-limiting biosensor package 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity. FIG. 2 illustrates that one or more features of the one or more biosensor modules 104 other than the one or more stimulus devices 112 can be integrated into a single layer (e.g., the one or more semiconductor substrates 110).


For example, in one or more embodiments the one or more sensors 108 and the one or more stimulus devices 112 can both be integrated within the semiconductor substrate 110. For instance, the semiconductor substrate can comprise gallium nitride. Further, in various embodiments, the one or more computer units 114 can also be integrated into the one or more semiconductor substrates 110. Thus, while FIG. 1 depicts a biosensor module 104 structure comprising one or more sensors 108, one or more stimulus devices 112, and/or one or more computer units 114 on respective layers; one or more embodiments can comprise a biosensor module 104 structure wherein one or more of the one or more sensors 108, one or more stimulus devices 112, and/or one or more computer units 114 are integrated onto a common layer (e.g., integrated onto and/or into the one or more semiconductor substrates 110).


Furthermore, FIG. 2 illustrates that the biosensor package 100 can comprise numerous chemical delivery systems 106 located adjacent to a side of the one or more biosensor module 104. For example, two or more chemical delivery systems 106 can be located adjacent to a left side and/or a right side of the one or more biosensor modules 104, as shown in FIG. 2. On of ordinary skill in the art will recognize that the number of chemical delivery systems 106 comprised within the polymer layer 102 can varying depending on the function of the biosensor package 100 and/or the dimensions of the biosensor package 100.



FIG. 3 illustrates a diagram of the example, non-limiting biosensor package 100 from a top point of view in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity. As shown in FIG. 3, a plurality of biosensor modules 104 can be embedded within the polymer layer 102 and/or arranged in an array.


The wall portions of the polymer layer 102 can separate biosensor modules 104 from each other and/or facilitate containing the plurality of biosensor modules 104 within the polymer layer 102. The elastomeric quality of the polymer layer 102 can enable the biosensor package 100 to wrap around and/or otherwise bend around various tissue structures so as to provide an array of biosensor modules 104 across irregular surface areas. Also, by comprising an array of biosensor modules 104 (e.g., as shown in FIG. 3) the biosensor package 100 can comprise redundancies that can be utilized in the case of malfunctions. In other words, the biosensor package 100 can remain functional despite damage and/or malfunction of a biosensor module 104 due at least in part to the existence of one or more adjacent biosensor modules 104 that can perform the same and/or a similar task.


Moreover, in various embodiments one or more of the biosensor modules 104 comprising the array of biosensor modules 104 that can characterize the structure of the biosensor package 100 can perform one or more different functions than one or more other biosensor modules 104 within the array. For example, a first biosensor module 104 within the array can comprise different sensors 108 and/or stimulus devices 112 than a second biosensor module 104 within the array. Therefore, the biosensor package 100 can perform a variety of tasks due to respective performance capacities of respect biosensor modules 104 comprising the biosensor package 100.


One of ordinary skill in the art will recognize that the number of biosensor modules 104 comprising the biosensor package 100 can vary depending on the size of the biosensor modules 104, the size of the biosensor package 100, the one or more desired functions of the biosensor package 100, the number of chemical delivery systems 106, a combination thereof, and/or the like. While FIG. 3 illustrates twelve biosensor modules 104, the biosensor package 100 can comprise fewer or additional biosensor modules 104. For example, the number of biosensor modules 104 comprised within the biosensor package 100 can range from, but is not limited to, greater than or equal to 1 and less than or equal to 10,000.



FIG. 4 illustrates another diagram of the example, non-limiting biosensor package 100 from a top point of view in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity. As shown in FIG. 4, the one or more biosensor modules 104 can be characterized by a variety of shapes.


While FIG. 3 depicts the one or more biosensor modules 104 as having a square shape, FIG. 4 exemplifies that the one or more biosensor modules 104 can have alternate shapes such as a triangular shape. Different structural shapes can facilitate different functions and/or unique properties of flexibility. For example, various structural shapes can offer achieve respective concentrations of the biosensor modules 104 in the polymer layer 102. Example shapes that can characterize the structure and/or dimensions of the one or more biosensor modules 104 can include, but are not limited to: squares, rectangles, triangles, hexagons, pentagons, octagons, decagons, a combination thereof, and/or other polygons. Further, although FIGS. 3 and 4 depict biosensor module 104 arrays comprising uniform shapes, the architecture of the biosensor package 100 is not so limited. For instance, the biosensor package 100 can comprise an array of biosensor modules 104 characterized by a variety of shapes.



FIG. 5 illustrates a diagram of the example, non-limiting polymer layer 102 from a cross-sectional view point in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity. FIG. 5 depicts the biosensor package 100 prior to the inclusion of the one or more biosensor modules 104 during a manufacturing process.


As shown in FIG. 5, the polymer layer 102 can form one or more pockets 502 defined by the one or more wall portions. The one or more biosensor modules 104 can be inserted and/or fixed into the one or more pockets 502 to manufacture the biosensor package 100. Wherein the biosensor package 100 comprises an array of biosensor modules 104, the polymer layer 102 can comprise a plurality of pockets 502 positioned in the orientation and/or configuration of the array. Further, FIG. 5 illustrates that the polymer layer 102 can comprise one or more chemical delivery systems 106 adjacent to one or more of the pockets 502. For example, the one or more chemical delivery systems 106 can be located within the polymer layer 102 (e.g., defined by the polymer layer 102) and/or between adjacent pockets 502, and thereby between adjacent biosensor modules 104 in the biosensor package 100. As described herein, the number of chemical delivery systems 106 can vary and/or the architecture of the polymer layer 102 is not limited to four chemical delivery systems 106 between adjacent pockets 502, as shown in FIG. 5 (e.g., the biosensor package 100 can comprise fewer or additional chemical delivery systems 106 between adjacent biosensors modules 104 in an array). Further, while FIG. 5 depicts the one or more chemical delivery systems 106 having uniform dimensions, the architecture of the biosensor package 100 is not so limited. For example, respective chemical delivery systems 106 can be characterized by respective dimensions.



FIG. 6 illustrates a diagram of an example, non-limiting system 600 that can comprise one or more biosensor packages 100 in accordance with one or more embodiments described herein. Repetitive description of like elements employed in other embodiments described herein is omitted for sake of brevity. As shown in FIG. 6, one or more biosensor modules 104 can be operably coupled to one or more controllers 602 via one or more networks 604.


The one or more controllers 602 can comprise one or more computerized devices, which can facilitate a user of the system 600 to monitor and/or control the one or more biosensor modules 104. Example computerized devices that can comprise the one or more controllers 602 can include, but are not limited to: personal computers, desktop computers, laptop computers, cellular telephones (e.g., smart phones), computerized tablets (e.g., comprising a processor), smart watches, keyboards, touch screens, mice, a combination thereof, and/or the like. Additionally, the one or more controllers 602 can comprise one or more displays that can present one or more outputs generated by the system 600 (e.g., the one or more biosensor modules 104) to a user. For example, the one or more displays can include, but are not limited to: cathode tube display (“CRT”), light-emitting diode display (“LED”), electroluminescent display (“ELD”), plasma display panel (“PDP”), liquid crystal display (“LCD”), organic light-emitting diode display (“OLED”), a combination thereof, and/or the like. A user of the system 600 can send instructions (e.g., program instructions) to the one or more biosensor modules 104 and/or can view data (e.g., representing one or more conditions monitored and/or detected by the one or more biosensor modules 104) outputted by the one or more biosensor modules 104.


The one or more networks 604 can comprise wired and wireless networks, including, but not limited to, a cellular network, a wide area network (WAN) (e.g., the Internet) or a local area network (LAN). For example, the one or more controllers 602 can communicate with the one or more biosensor modules 104 (and vice versa) using virtually any desired wired or wireless technology including for example, but not limited to: cellular, WAN, wireless fidelity (Wi-Fi), Wi-Max, WLAN, Bluetooth technology, a combination thereof, and/or the like.


The one or more biosensor modules 104 can comprise one or more reception and/or transmission components, such as one or more antennas (e.g., factual antennas). The one or more reception and/or transmission components can be operably coupled to the one or more computer units 114 and/or the one or more power devices 116. Further, the one or more reception and/or transmission components can be protected by the polymer layer 102 from the biological environment surrounding the biosensor package 100. In one or more embodiments, the one or more reception and/or transmission component can be integrated into the one or more computer units 114. The one or more reception and/or transmission components can facilitate connection between the one or more biosensor modules 104 and/or the one or more networks 604, and thereby the one or more controllers 602. For example, the one or more biosensor modules 104 can, via the one or more networks 604, receive (e.g., from the one or more controllers 602) one or more instructions (e.g., program instructions) to be executed by the one or more computer units 114 and/or transmit (e.g., to the one or more controllers 602) data representing one or more operations of the biosensor module 104 and/or the biosensor package 100.


The one or more biosensor modules 104 can communicate with the one or more controllers 602 and/or with one or more other biosensor modules 104 (e.g., via the one or more networks 604). For example, the one or more biosensor modules 104 can communicate with other biosensor modules 104 comprising the same biosensor package 100. In another example, the one or more biosensor modules 104 of a first biosensor package 100 can communicate with one or more biosensor modules 104 of a second biosensor package 100.


The various embodiments of the biosensor package 100 described herein can facilitate treatment of various intractable health conditions such as chronic pain, depression, schizophrenia, epilepsy, diabetes, obesity, Parkinson's disease, and/or muscle tissue control. The biosensor package 100 can be implanted in one or more locations throughout a patient's body to manipulate, monitor, and/or modify desired segments of tissue. For example, the biosensor package 100 can be implanted into body regions that are typically difficult to reach, sensitive to intrusion, and/or subject to flexibility (e.g., due to motion). For instance, the biosensor package 100 can be implanted into brain regions, spinal regions, and/or nervous system regions.


In one or more embodiments, the biosensor package 100 can be utilized to facilitate one or more optogenetic methods of treatment. For example, the one or more biosensor modules 104 can act as optogenetic stimulation devices. One or more biosensor packages 100 can be fixed to a subject tissue segment via known medical techniques (e.g., stitches and/or medical adhesive). The one or more biosensor modules 104 can monitor one or more conditions of the surrounding tissue. Also, the one or more biosensor modules 104 can comprise one or more LEDs to stimulate the surrounding tissue using light. Moreover, the one or more chemical delivery systems 106 can be loaded with one or more chemical compounds that can facilitate manipulations of the surrounding tissue via light stimulation.


For example, the biosensor package 100 can be implanted into a brain section and/or the one or more chemical delivery systems 106 can be loaded with a hydrogel comprising: a virus carrying genetic material for the expression of opsin protein, and/or opsin protein itself. The biological environment surrounding the biosensor package 100 can dissolve and/or other degrade the hydrogel, thereby releasing the virus and/or opsin protein. The virus can infect one or more local neurons with the genetic material, thereby causing the neurons to produce opsin protein. The opsin protein (e.g., either released by the chemical delivery system 106 and/or produced by the neurons) can embed into the cellular membrane of the local neurons. The opsin protein can form an ion channel within the cellular membrane and be sensitive to light. For example, the opsin protein can open the ion channel in the presence of blue light and close the ion channel in the absence of light. The ion channel can facilitate a flow of ions and thereby control the electric potential of a subject neuron.


The one or more biosensor modules 104 can thereby control one or more functions of the local neurons by stimulating and/or not stimulating the opsin protein positioned within the local neurons. For example, by emitting blue light, the one or more biosensor modules 104 can affectively activate one or more local neurons. Conversely, by ceasing to emit blue light, the one or more biosensor modules 104 can affectively deactivate one or more local neurons. Said activation and/or deactivation can be controlled by the one or more controllers 602 (e.g., via the one or more networks 604) to achieve one or more treatment conditions. One of ordinary skill in the art will further recognize that the biosensor package 100 can be used for a variety of medical treatments in addition to optogenetic.

At 906, the method 900 can comprise releasing the polymer layer 102 from the mold (e.g., injection mold 800). Releasing the polymer layer 102 from the mold (e.g., injection mold 800) can facilitate further manufacturing of the biosensor package 100.


At 908, the method 900 can comprise loading a hydrogel matrix (e.g., comprising hyaluronic acid polymer) into one or chemical delivery systems 106, which can be defined by the polymer layer 102.
