Embodiments disclosed herein relate to a garment sleeve. Certain embodiments disclosed herein relate to a garment sleeve for monitoring biometric information associated with a limb wearing the sleeve and associated methods.
Wearable technology has become an increasingly more common resource for users to track and monitor their biometric data during physical activity and/or day-to-day activity. Devices such as wristbands, glasses, and watches have been developed that function to gather biometric data from an individual's body such as heart rate, force on a body, acceleration of a body, etc. These devices, however, may not be capable of tracking or generating a complex profile of a user's biometric data in combination with movement and body position of the user. Thus, there is still are needs for systems (e.g., a garments) that are capable of generating biometric data for real-time analysis and/or historical tracking of an individual's condition. Based on the foregoing currently existing technologies and processes for monitoring and analyzing biometric data may be enhanced and improved upon so as to provide increased functionality and quality of data for users. Such enhancements may facilitate a better understanding of biometric data, more accurate data, enhanced monitoring of biometric data, enhanced biometric data capture techniques, improved outputs generated based on the biometric data, among other benefits.
In certain embodiments, a system includes a fabric for being worn by a wearer. The fabric may include one or more layers. At least one layer of fabric may have a geometric pattern of conductive elastic material interspersed with non-conductive elastic material. A plurality of sensor units may be integrated in the fabric. At least a portion of the conductive elastic material may be coupled between at least two sensor units. The at least two sensor units may assess a resistance of the portion of the conductive elastic material between the at least two sensor units. A positioning component may be integrated in the fabric. The positioning component may be positioned at a joint of the limb when the fabric is worn on the limb. A first inertial measurement unit may be integrated in the fabric and positioned on a first side of the positioning component. A second inertial measurement unit may be integrated in the fabric and positioned on a second side of the positioning component. A processor may be integrated in the fabric. The processor may receive data from the sensor units and the first and second inertial measurement units. The processor may assess shape, position, and movement of the limb using the received data.
In certain embodiments, a method includes assessing a resistance of a portion of a conductive elastic material interspersed with non-conductive elastic material in a geometric pattern in a fabric. The resistance may be assessed using at least two sensor units coupled to the portion of the conductive elastic material. The fabric may be worn on a limb of a user. Motion of an upper portion of the limb may be assessed using a first inertial measurement unit integrated in a portion of the fabric worn on the upper portion of the limb. Motion of a lower portion of the limb may be assessed using a second inertial measurement unit integrated in a portion of the fabric worn on the lower portion of the limb. A processor integrated in the fabric may receive resistance data from the at least two sensor units and motion data from the first inertial measurement unit and the second inertial measurement unit. Shape, position, and movement of the limb of the wearer may be assessed using the received data.
In an embodiment, a system for monitoring biometric data by utilizing a garment sleeve is disclosed. The system may include a fabric for being worn on a limb of a wearer. In certain embodiments, the fabric comprises one or more layers. In certain embodiments, at least one layer of the one or more layers of the fabric may comprise a geometric pattern of conductive elastic material interspersed with non-conductive elastic material. The system may also include a plurality of nodes integrated in the fabric. A first portion of the conductive elastic material may be coupled between at least two nodes. The system may include a positioning component integrated in the fabric, a first inertial measurement unit integrated in the fabric and positioned on a first side of the positioning component, and a second inertial measurement unit integrated in the fabric and positioned on a second side of the positioning component. The system may further include a processor integrated in the fabric, which may be configured to assess a resistance of the first portion of the conductive elastic material between the at least two nodes and receive data from the first and second inertial measurement units.

In certain embodiments, sleeve 100 includes fabric 102. Sleeve 100 may, for example, be made up of fabric 102. In certain embodiments, fabric 102 may be included as part of sleeve 100 along with other components (e.g., other materials or structural components). In some embodiments, fabric 102 includes one or more fabric layers with elastic fibers similar to spandex. In some embodiments, fabric 102 includes a plurality of fabrics or yarns arranged in a woven and/or a knit pattern. For example, fabric 102 may include a plurality of materials interspersed together (e.g., interlaced or interwoven together). In some embodiments, fabric 102 includes fabric enhancements such as, but not limited to, improved moisture wicking, improved thermal management, and/or muscle group support.
Sleeve 100 may be made available in a number of sizes. For example, sleeve 100 may be available in in a range of sizes to accommodate different limb or body part diameters (e.g., different limb girths). Sleeve 100 may be available in different sizes to ensure the sleeve is form fitting and snug on the limb to accurately measure physiological responses. In some embodiments, sleeve 100 is designed to be worn for prolonged periods of time and/or under other equipment (e.g., under shirt sleeves or equipment pads).
In certain embodiments, sleeve 100 includes positioning component 104. In some embodiments, positioning component 104 may include a shaped component that conforms to a joint of the user's limb (e.g., the elbow or knee joint). The shaped component may be designed such that sleeve 100 is positioned at or near the same location in each instance that the sleeve is worn by the user. In some embodiments, positioning component 104 includes a marker or indicator. The marker or indicator may be used to mark or indicate proper position of sleeve 100. In some embodiments, positioning component 104 includes a combination of the shaped component and the marker or indicator. Using positioning component 104 to ensure sleeve 100 is properly positioned in repeated uses of the sleeve may provide more reliable and accurate results about shape, movement, and position of the limb using the sleeve, measured as described herein.
As shown in
In some embodiments, inertial measurement units 106 provide accelerometer-based measurements. For example, inertial measurement units 106 may provide the position or orientation of sleeve 100 relative to perpendicular and/or relative to the ground. The position or orientation of sleeve 100 may provide the position or orientation of the limb relative to perpendicular and/or relative to the ground. Providing position and/or orientation of the limb (or portions of the limb) may allow an evaluator to determine the activity of the limb (e.g., throwing, running, swimming, etc.). In some embodiments, inertial measurement units 106 may provide position and/or orientation information relative to each other.
In certain embodiments, sleeve 100 includes inertial measurement unit 106A above the joint location of the sleeve (e.g., above positioning component 104) and inertial measurement unit 106B below the joint location. Inertial measurement units 106A, 106B may be capable of measuring motion with multiple degrees-of-freedom. For example, inertial measurement units 106A, 106B may measure motion with nine (9) degrees-of-freedom. Thus, sleeve 100 may be capable of measuring motion of the limb with nine degrees-of-freedom both above and below the joint location of the sleeve along with relative motion between portions of the limb above and below the joint location. Inertial measurement units 106 may provide data that may be used in combination with other data described herein (e.g., muscle motion/shape data, heart rate data, etc.) to provide a three-dimensional image of position and movement of the limb in space.
In some embodiments, material 108 is interspersed into material 110 (e.g., material 108 is laced into or woven into material 110). For example, material 108 may be fibers or wiring engrained or partially engrained within seams of sleeve 100 (e.g., within seams of material 110). In some embodiments, material 108 and material 110 are formed as “panels” of fabric 102. For example, material 108 (e.g., the conductive material) may be used as borders for panels of material 110 (e.g., the non-conductive material). The panels may then be interspersed (e.g., interlaced or interwoven) together to form the geometric pattern shown in
In some embodiments, the panels are made of multi-layers of fabric.
In certain embodiments, bottom layer 118 includes material 108 (e.g., the conductive material) as borders for material 110 (e.g., the non-conductive material). Material 108 may be, for example, conductive polymer, conductive flexible fibers, or another conductive flexible (elastic) material. In some embodiments, material 108 includes a rubberized conducive material, such as, but not limited to a metal rubber. Metal rubber may provide an ideal set of properties including elasticity and conductivity. When an individual is wearing sleeve 100, bottom layer 118 may be adjacent the individual's skin Material 108 in bottom layer 118 may receive a natural current from the individual's skin that may be transmitted throughout the bottom layer. In certain embodiments, as described herein, this natural current may be measured by one or more sensor units, which may output data that is assessed to show the shape of the limb.
Midsection 116 may be an insulative fabric such as, but not limited to, a woven textile including insulative fibers. In some embodiments, midsection 116 may include crosslinked material. It should be noted that the insulative fibers of the woven textile may be adjacent bottom layer 118 so that the bottom layer may carry a charge from one point to another without midsection 116 interfering with the current passed through the bottom layer. Top layer 114 may include an elastic fabric such as, but not limited to spandex and Lycra. In certain embodiments, midsection 116 is adhered to the top and bottom layers 114, 118 via an adhesive polymer. In some embodiments, the woven textile of midsection 116 is woven to at least one of the top and bottom layers 114, 118.
In certain embodiments, as shown in
In certain embodiments, sensor units 120 detect the changes in the resistance of material 108 that results from the expansion and contraction of the muscles in the limb. Material 108 may have a defined length and width (e.g., area) between two sensor units 120. With the defined (known) area of material 108 between two sensor units 120, the sensor units may assess changes in shape and/or motion of the limb (e.g., expansion and/or contraction of muscles in the limb) based on assessed changes in the resistance of the material.
In some embodiments, sensor units 120 assess resistance (and changes in resistance) of material 108 between sensor units by assessing (e.g., measuring) electrical currents passing through the sensor units. For example, sensor units 120 may assess currents passing through the sensor units along portions of material 108 connected to the sensor units. Resistance may then be determined from the assessed (measured current).
In some embodiments, transmission time between sensor units 120 may be used to assess resistance changes in material 108 between sensor units. For example, while wearing sleeve 100, changes in shape and/or motion of muscles in the user's limb may cause material 108 to elongate and conductive fibers in the material to become uniformly thinner. As the conductive fibers become thinner, the resistance along the conductive fibers increases. Because of the increased resistance, the transmission time of the electrical signal across material 108 increases. These transmission times may be recorded in sensor units 120 placed within sleeve 100. The recordation of transmission times may be included in information/data packets sent to processor 130 as described herein.
In some embodiments, sensor units 120 assess change in resistance of material 108 using strain detection.
As the material in panel 122 includes conductive material (e.g., conductive polymer or conductive fiber), the resistance of the conductive material changes. When the area of the conductive material decreases, its resistance increases. Deflection (e.g., expansion and contraction) of the conductive material results in a decrease in the cross-sectional area and a corresponding change in the resistance of the conductive material.
Strain detection units 124A and 124B may detect the changes in the resistance of the conductive material in panel 122 that results from the stretching or relaxing of the material that accompanies expansion and contraction of muscles in the limb. Latch 126 may capture the results of the detection performed by strain detection units 124A, 124B. Data captured by latch 126 may be provided to, for example, processor 130, as described herein.
Thus, when the resistance of the material, illustrated here as RCE, changes, the output voltage provided to amplifier 136 reflects that change as a change in voltage which is then conditioned and amplified by amplifier 136. The amplified signal is then converted to a digital output by ADC 132′. As before, ADC 132′ may be a simple 1-bit ADC, a more complex 24-bit ADC, or something in between, depending upon the application and the needs of the system.
In certain embodiments, sensor units 120 generate one or more data packets with the assessed resistance data associated with material 108 in sleeve 100. The assessed resistance data may include, for example, resistance measurements themselves as assessed by sensor units 120. In some embodiments, the resistance data in the data packets may include data that can be used to determine the resistance data of material 108. For example, the resistance data may include current measurements, transmission time measurements, or digital voltage outputs, as described above. In certain embodiments, the data packets may include time stamps for the measurements and/or identification information for sensor units 120 (e.g., a unique ID associated with the sensor unit sending the data packet). Sensor units 120 may send the data packet(s) to either a processor integrated in sleeve 100 (e.g., processor 130, as shown in
In certain embodiments, sleeve 100 includes processor 130, as described herein and shown in
In certain embodiments, wireless transmitter 140 is coupled to processor 130 and memory 138. Wireless transmitter 140 may be capable of wireless transmission/receiving using a wireless transmission protocol. Wireless transmission protocols utilized by wireless transmitter 140 may include, but not be limited to, cellular transmission, satellite transmission, Bluetooth (including different variations of Bluetooth transmission protocols), ANT+, Zigbee, Wi-Fi, LiFi, and SATCOM. Transmitted information may include either processed information and/or raw data information. In some embodiments, wireless transmitter 140 provides burst transmission of information (e.g., transmits bundles of information at a specified time).
As shown in
In some embodiments, wireless transmitter 140 provides for the addition of third-party hardware for extended biofeedback response capabilities. Some possible hardware concepts include, but are not limited to, glasses to track movement and pupil dilation, wristbands to monitor skin conductivity and temperature, ambient temperature sensors, and DTR (deep tendon reflex) monitoring. In some embodiments, wireless transmitter 140 includes small transmitters and receivers capable of moving large quantities of data and smaller package sizes over greater distances. Wireless transmitter 140 may utilize protocols to include a wide variety of third-party hardware. In some embodiments, submersible technology may be incorporated in wireless transmitter 140.
As described above, processor 130 may receive data (e.g., information) from inertial measurement units 106 and/or sensor units 120. In certain embodiments, processor 130 receives the data from inertial measurement units 106 and/or sensor units 120 via wireless transmission (e.g., through wireless transmitter 140). In some embodiments, processor 130 receives the data via wired transmission. For example, inertial measurement units 106, sensor units 120, and processor 130 may be coupled to material 108 (e.g., the conductive material). Material 108 (e.g., wiring in sleeve 100) may then be used to transmit/receive data between inertial measurement units 106, sensor units 120, and processor 130. In some embodiments, separate wiring in sleeve 100 may be used to transmit receive data between inertial measurement units 106, sensor units 120, and processor 130.
Data received by processor 130 may be used to determine biometric properties of the user's limb associated with sleeve 100.
As described above, assessing resistance between sensor units in 202 may include assessing the resistance (or changes in resistance) of material 108 between sensor units 120, shown in
As described above, assessing motion of the upper portion of the limb in 204 may include measuring motion of the upper portion of the limb with inertial measurement unit 106A, which is above positioning component 104, as shown in
As shown in
In certain embodiments, limb biometric data 218 includes multi-dimensional images of the shape, position, and/or movement of the limb in sleeve 100. For example, the combination of measurements from portion 108A and portion 108B of material 108, shown in
As described above, sleeve 100 may be capable of measuring motion of the limb with nine degrees-of-freedom both above and below the joint location of the sleeve along with relative motion between portions of the limb above and below the joint location using inertial measurement units 106A and 106B. Data from inertial measurement units 106A and 106B may be combined with data from sensor units 120 to provide a three-dimensional image of the motion of the limb including shape, position, and movement of the limb in space. In some embodiments, the three-dimensional motion image may be combined with other measurements possible with sleeve 100 described herein (e.g., heart rate data 220, skin response data 222, 02 saturation data 224) to provide a biometric assessment of the wearer of sleeve 100 in limb biometric data, as shown in
In certain embodiments, as shown in
Heart rate monitor 140 may be, for example, a standard heart rate monitor that circumnavigates either a portion of the user's limb or torso. Heart rate monitor 140 may function utilizing decoding algorithms and EKG equivalent monitoring techniques. In some embodiments, heart rate monitor 140 may integrate a three lead EKG equivalent monitor (e.g., a lead measured between three electrode sites (+, −, and ground). Heart rate monitor 140 may, however, integrate any number of leads. Heart rate monitor 140 may track pulse rate (and/or other heart related information) in near real-time. Heart rate monitor 140 may stream pulse rate or other data to processor 130 (e.g., via wires as described above) as heart rate data 220, shown in
In certain embodiments, as shown in
In certain embodiments, as shown in
In some embodiments, sleeve 100 includes a GPS component. The GPS component may be included as part of processor 130 or another component in sleeve 100. The GPS component may include, for example, a GPS monitor and/or a WWAN monitor. The GPS monitor may be stacked or swapped with the WWAN monitor for indoor movement tracking in a 3D space. The GPS component may be utilized to track the physical location of the limb (and the wearer's body) in a real-time environment. For certain purposes (e.g., military purposes), the GPS component may be capable of utilizing WWAN to track a wearer through an interior environment. WWAN integration may afford observers utilizing a dashboard application (as described herein) to track the sleeve's wearer in near real time on a map overlay. In some embodiments, the GPS component includes one or more small units that provide good satellite tracking, fast locking, and good transmission through dense cover.
In certain embodiments, as shown in
Dashboard application 230 may be associated with sleeve 100 to provide simultaneous review of all biometric information assessed by the sleeve as well as complementary information generated by the processing of acquired data (e.g., algorithmic manipulation of acquired data). Dashboard application 230 may allow for the management, utilization, and near real-time review of gathered data regardless of the physical location of device 300 relevant to sleeve 100. In some embodiments, dashboard application 230 is a native iOS or Android application as well as a web platform. In some embodiments, dashboard application 230 may provide additional processing of data received from sleeve 100.
Dashboard application 230 may be capable of accessing a remote server associated with sleeve (e.g., through a secure Internet connection). Dashboard application 230 may provide capability for the passing of information and system management tools between sleeve 100 and the remote server. This setup may allow for wireless firmware updates and remote diagnostic capabilities of sleeve 100. Live “over-the-wire” firmware updates may occur as enhancements are made and process 130 may be updated as improvements occur. Initially, dashboard application 230 may allow for the measurement and viewing of all biometric processes being monitored and GPS location.
In some embodiments, communication between processor 130 and dashboard application 230 is substantially continuous (e.g., limb biometric data 218 is continuously transmitted to the dashboard application by the processor). In some embodiments, processor 130 may provide burst transmission of data to dashboard application 230. For example, processor 130 may store data in memory 138 in the event of communication loss between the wireless transmitter 140 and device 100. Upon reestablishment of the communication link, burst transmission of the data may be provided to update dashboard application 230 with data as quickly as possible.
In certain embodiments, dashboard application 230 may display data received from processor 130 and/or information generated from the data received from the processor on a display of device 300. Dashboard application 230 may display data such as, but not limited to, limb biometric data 218, information generated from the limb biometric data, and other data obtainable from sleeve 100 (e.g., GPS data). Dashboard application 230 may also store data received on device 300 so that data history for sleeve 100 (and the wearer of the sleeve) can be accessed at later times. In some embodiments, dashboard application 230 may transmit data for storage on a remote server (e.g., a cloud-based server).
As described herein, sleeve 100 may provide an effective system for tracking movement of a limb along with an array of biometric properties associated with the limb. Sleeve 100 may, for example, provide tracking of gait mechanics of the limb, limb movement, heart rate, and autonomic tone. Tracking of these properties may be substantially simultaneous using sleeve 100. Tracking of these properties may also be provided in real-time as the limb is being used.
Sleeve 100, as described herein, may be used in a range of applications including medical applications. Medical applications may include, but not be limited to, fall predication and early diagnosis of Parkinson's disease. Sleeve 100 may also provide capability for three-dimensional computer modeling of the limb, sports performance tracking, and/or biofeedback training.
The following non-limiting examples provide different embodiments of use of sleeve 100.
Sleeve 100 may be used to detect signs associated with neuromuscular diseases such as, but not limited to, amyotrophic lateral sclerosis, multiple sclerosis, myasthenia gravis, neuromuscular junction disease, spinal muscular atrophy, and Parkinson' disease. In an example, a 60-year old male may be doing an annual physical with a physician. The male subject may put on sleeve 100 during his exam and wear the sleeve while walking around the room. Data obtained by sleeve 100 may show a decrease in arm swing and axial rotation amplitude, with less smoothness than the previous year. The trend shown by sleeve 100 may indicate a potential path towards Parkinson's disease in later years.
By identifying the indicators from sleeve 100 early on, the physician may propose that further testing is necessary as there may be a high probability of Parkinson's disease in the future. The physician may also start early treatment to slow onset and progression of Parkinson's disease. Typically, the earliest features of Parkinson' disease develop slowly and begin to manifest years before a formal diagnosis is possible. Early identification and treatment may be a critical factor in managing the disease, easing its progression, and providing the patient with a more satisfying quality of life.
Reduced arm swing during gait has long been a classical marker of Parkinson's disease. Recent research has focused on using gait analysis to identify variations in arm swing and axial rotation that preclude the onset of Parkinson's disease while the disease is still in the prodromal stage, prior to when a formal diagnosis can be made. For example, the disease susceptibility may be assessed in otherwise healthy people via gait analysis using sleeve 100. This may allow for more rapid identification of high-risk individuals. Earlier identification of Parkinson's disease susceptibility may allow for earlier intervention, which can mitigate and slow progression of the disease.
During gait analysis, the two primary indicators of prodromal motor features (the earliest signs of future Parkinson's disease) are decrease arm swing amplitude and axial rotation. Arm swing amplitude is the total distance that each arm reaches forward and back while the subject is waling. Axial rotation is the amount of rotation occurring at the thoracic spine combined with protraction and retraction (reaching forward and pulling back) of the shoulder blade across the ribcage. Side to side asymmetry of these movements may be another indicator of prodromal status.
Sleeve 100 may enable detailed measurement of both arm swing amplitude and axial rotation (as well as other limb-based factors). For example, inertial measurement units 106 may assess transverse, frontal, and sagittal plane arm swing amplitude as well as elbow flexion/extension and wrist rotation during gait. At the same time, sensor units 120 may assess axial rotation by tracking the reciprocal amplitude of rotation at the shoulder of each arm.
Sleeve 100 may provide this limb biometric data, including heart rate variability, for analysis by the physician or another research. The analysis may be used to observe variations in gait mechanics that preclude Parkinson's disease as well as other potential indicators such as aberrant heart rate variability and changes in SPO2 saturation. Sleeve 100 may allow a more complete picture of the inner and outer workings of the subject's body and provides a better picture into the body's physiological interactions. Thus, sleeve 100 may provide enhanced ability for early detection of Parkinson's disease and allow for earlier treatment to provide a more positive impact on the lifespan and quality of life of the subject.
A software designer may be attempting to use digital 3D (three-dimensional) modeling to create images of a person's body in motion. Sleeve 100 may be used to track detailed three-dimensional motion of motion of the person's limbs in an easy and accurate manner. For example, a model may wear one or more sleeves 100 and go through motions needed by the software designer. The data stream (e.g., stream of biometric data) from sleeves 100 may show shoulder, elbow, and wrist motion of the arms while also displaying changes in the shapes of muscles in the arm as the arms move.
A rugby player may be training in a weight room. The player may be concerned with shorter-term physical performance along with building resilience to reduce the risk of injury. Years of conventional gym training may have created lots of strength and tension in the sagittal plane extension—i.e., the player is good at squatting, deadlifting, and pressing. This tension bias into a single plane of motion may, however, have created some pattern rigidity. For example, the player may have tight extensors, such as muscles in the lower back, and the player's ability to dynamically change direction and move laterally and rotationally on the field may have decreased. Thus, while the player may be better at picking up a barbell, the player may be falling behind competitively in many aspects of the sport due to deterioration of movement availability on the field. The player may be more achy, prone to small injuries, and not recovering as well because the player cannot turn off the tension that the body has been training towards for years.
To overcome these issues, the player may use sleeve 100 to track training movements and adjust the player's training to incorporate more lateral and transverse plane movement. Such movement may have a particular focus on alternating reciprocal motion at the arms and thorax during movements like lunges, step-ups, and single-arm presses or rows. Using sleeve 100 in training at the gym to focus on these movements, the player may now incorporate natural thoracic rotation and scapulae/arm reach found in running and jumping. Sleeve 100 may be used to monitor and assess these movements. Sleeve 100 may track how well the player is moving rotationally during strength movements and, potentially, provide haptic feedback to correct the movement if the player falls into old training patterns. Additionally, sleeve 100 may be tracking other biometric properties such as heart rate to help monitor exertion and recovery during the workouts.
A 70-year old female may potentially be having issues with balance and is worried about falling. The female may utilize sleeves 100 to monitor her gait and warn of impending falls. Sleeves 100 may, for example, monitor for sudden changes in gait mechanics including stability, variability, smoothness, and symmetry as well as arm swing amplitude and axial rotation. Sleeves 100 may simultaneously monitor autonomic tone via changes in heart rate variability that could indicate a shift towards a threatened or highly stressed state. Each of these properties may be positively correlated with falls in the elderly and be used to predict a fall.
The female may wear sleeves 100 during normal daily life patterns. She may not normally notice sleeves 100 until she is alerted that a shift in her movement indicates a probability of a fall. The alert triggered by sleeves 100 may focus her attention to her movement and make her realize that she is feeling more unstable than normal. She may then immediately seek to rest (e.g., sit down) for a moment to regain her normal stability. Heart rate and heart rate viability tracking in sleeves 100 may provide her an indication (e.g., after a few minutes of rest) that she has stabilized and that she may safely continue with her activity.
A 27-year old climber had his left biceps muscles removed following a traumatic fall that was untreated for several hours. His humerus, though fractured, was intact. A surgical team performed a latissimus dorsi transposition for a biceps reconstruction. There were no complications during or after the surgery. The goal of medical treatment and rehabilitation after the surgery is to restore as much function as possible to his left arm. Major upper arm amputations require functional restoration of elbow flexion.
