The present disclosure generally relates to the field of medical and physiological equipment and technology, and more particularly to a physiological monitoring sensor strip and a method for manufacturing the same, a physiological monitoring mattress and a physiological monitoring system including the same.
Physical indicators, such as breath and heartbeat, are of great significance for monitoring human health and diagnosing and treating disease, particularly for patients. However, there are many problems exist in the existing instruments for monitoring physical indicators, such as breath and heartbeat.
Most existing respiratory monitoring equipment is expensive and complicated, and needs to be operated by a professional. In addition, individual is required to wear a nose-mouth type monitor when monitored, which is likely to cause discomfort and psychological pressure to individual being monitored.
Most existing heartbeat monitoring equipment is electrocardiograph (ECG) which commonly is very expensive and requests an operator to be professional trained. Moreover, individual is required to paste a plurality of lead electrodes when monitored, which leads an upper body of the individual to be covered with connected wires, which is likely to cause a great psychological pressure to individual, and thus interferes with diagnostic results. In addition, ECG signal also is susceptible to external electromagnetic interference. Further, when the individual is sleeping, the lead electrodes pasted on the body of the individual may fall off as the individual changes his sleeping position, which eventually lead to a failure of the whole monitoring, and thus unable to achieve the purpose of monitoring.
In addition, most existing instruments for monitoring physical indicators, such as breath and heartbeat, are used independently for monitoring a special item. For example, the existing electrocardiograph (ECG) does not take a function for monitoring breath into consideration, the existing respiratory monitoring equipment does not take a function for monitoring heartbeat into consideration, either, which makes it difficult to real-timely and comprehensively monitor the health condition of the individual being monitored.
In summary, the existing instruments for monitoring physical indicators, such as breath and heartbeat, prevalently have a plurality of drawbacks, such as single function, susceptible to external interference, poor reliability, complex structure and manufacturing process, complicated operation, and high cost.
An object of the present disclosure directs to drawbacks in the related art, providing in embodiments a physiological monitoring sensor strip and a method for manufacturing the same, a physiological monitoring mattress, and a physiological monitoring system, so as to solve the problems exiting in the related art, such as single function, susceptible to external interference, poor reliability, complex structure and manufacturing process, complicated operation, and high cost.

Take monitoring sleep as an example, when a person is in a quiet sleep, physiological electric signals (such as voltage signals) output by the physiological monitoring sensor strip may reflect the frequencies and/or waveforms of breath and heartbeat of the person in the quiet sleep; when the person turns over, leaves the bed, or snores in the sleep, the physiological monitoring sensor strip may output physiological electric signals significantly different from that output when the person is in the quiet sleep. All of those provide an accurate and reliable data base for analyzing a sleeping quality and health condition of human body.

Description will be made in detail with reference to the following specific embodiments in order to fully understand the purpose, characteristics and effects of the present disclosure, but the embodiments shall not be construed to limit the present disclosure.
A physiological monitoring sensor strip according to an embodiment of the present disclosure is manufactured based on the principle of triboelectric, and includes a first triboelectric layer, a second triboelectric layer, an insulation layer, an electric conduction shielding layer, and a first extraction electrode and a second extraction electrode acting as outputting electrodes of the physiological monitoring sensor strip. The first triboelectric layer and the second triboelectric layer are in a stacked arrangement, between which a triboelectric interface is formed. The insulation layer wraps the first triboelectric layer and the second triboelectric layer. The electric conduction shielding layer wraps the first triboelectric layer, the second triboelectric layer, and the insulation layer. The first extraction electrode and the second extraction electrode are connected to the first triboelectric layer and the second triboelectric layer, respectively; or the first extraction electrode is connected to the first triboelectric layer or the second triboelectric layer, and the second extraction electrode is connected to the electric conduction shielding layer.
The physiological monitoring sensor strip according to an embodiment of the present disclosure may be directly laid inside a mattress, on an upper surface of the mattress, on a lower surface of the mattress, or in an effective area within a certain distance from the mattress such that the physiological monitoring sensor strip may monitor human physical conditions normally and reflect human health status real-timely, without the need of being worn.
Alternatively, the physiological monitoring sensor strip according to an embodiment of the present disclosure may also include a protection layer wrapping an outer surface of the electric conduction shielding layer. The protection layer is disposed to not only protect an internal structure of the physiological monitoring sensor strip, thereby avoiding normal work of the internal structure from being affected by external environmental factors; but also to ensure the internal structure a clean environment; as well as to affix the physiological monitoring sensor strip to the mattress according to actual demands. The protection layer may be configured to be a detachable structure such that it is convenient for cleaning so as to ensure the physiological monitoring sensor strip the cleanness and sanitation.
The insulation layer may fully wrap both the first triboelectric layer and the second triboelectric layer to form a fully-wrapped structure, while the insulation layer may also fully wrap the first triboelectric layer but partially wrap the second triboelectric layer such that a partial region of the second triboelectric layer is in contact with the electric conduction shielding layer, forming a partially-wrapped structure. Structures of the physiological monitoring sensor strip will be described in detail with reference to several specific embodiments hereinafter.
The insulation layer 13 is a single-side adhesive or double-side adhesive insulation tape, such as a polyethylene terephthalate tape, i.e. a PET tape, the insulation tape fully wraps the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 1 2 to form a sealed-structure, i.e. a fully-wrapped structure. The insulation layer 13 wraps the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 12, so as on one hand to play functions of waterproof and moistureproof, and thus omit a process of moistureproof treatment on the outermost surface, on the other hand to achieve package of the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 12, and thus avoid the triboelectric electricity generation of the first macromolecule polymer insulation layer 11 and the second macromolecule polymer insulation layer 12 from being affected by the external environmental factors.
The electric conduction shielding layer 14 is a single-side adhesive or non-adhesive conductive tape, and fully wraps the outer surface of the insulation layer 13. In the case that the insulation layer 13 is the single-side adhesive insulation tape, then the electric conduction shielding layer 14 is the single-side adhesive conductive tape. In specific, an adhesive-side of the insulation layer 13 is attached to the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 12, an adhesive-side of the electric conduction shielding layer 14 is attached to the outer surface of the insulation layer 13. In the case that the insulation layer 13 is the double-side adhesive insulation tape, then the electric conduction shielding layer 14 is the non-adhesive conductive tape. In specific, a first adhesive-side of the insulation layer 13 (i.e. an inter surface of the insulation layer 13) is attached to the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 12, and the electric conduction shielding layer 14 is attached to a second adhesive-side of the insulation layer 13 (i.e. the outer surface of the insulation layer 13).
The protection layer 15 may be a fabric or plastic layer, or a plastic film. In the case that the protection layer 15 is the plastic layer, then the protection layer 15 is made of thin plastic. The protection layer 15 is configured to not only protect the internal structure (the first electrode 10, the first macromolecule polymer insulation layer 11, the second macromolecule polymer insulation layer 12, the insulation layer 13, and the electric conduction shielding layer 14) of the physiological monitoring sensor strip, thereby avoiding normal work of the internal structure from being affected by external environmental factors; but also to ensure the internal structure a clean environment; as well as to fix the physiological monitoring sensor strip to the mattress according to actual demands. Preferably, the protection layer 15 may be configured to be a detachable structure such that it is convenient for cleaning so as to ensure the physiological monitoring sensor strip the cleanness and sanitation. Certainly, the physiological monitoring sensor strip described above may be without the protection layer 15.
In this embodiment, the first electrode 10 is a single-side adhesive conductive tape, and is attached to the first macromolecule polymer insulation layer 11 with an adhesive-side thereof. In addition, an electrode material (such as indium tin oxide, graphene, silver nanowire film, metal or alloy) may also be directly disposed on the first macromolecule polymer insulation layer 11 to form the first electrode 10 by means of a coating or sputtering process, which will not be limited herein.
The first electrode 10 is connected to the first extraction electrode 16 by a riveting way which can be customized according to customer requirement without being limited herein. In specific, a first end of the first extraction electrode 16 is directly riveted on the conductive tape used as the first electrode 10. The electric conduction shielding layer 14 is connected to the second extraction electrode 17 also by the riveting way which is not limited herein. In specific, a first end of the second extraction electrode 17 is directly riveted on the conductive tape used as the electric conduction shielding layer 14.
In this embodiment, the second extraction electrode 17 is a grounding electrode, that is, the electric conduction shielding layer 14 is grounded. Varying degrees of triboelectric is generated between the first macromolecule polymer insulation layer 11 and the second macromolecule polymer insulation layer 12 when the physiological monitoring sensor strip is subjected to a pressure caused by, such as weak breath, heartbeat, turning over, leaving the bed, snoring and so on during sleeping, such that the first electrode 10 induces corresponding charges, and thus varying degrees of potential differences are present between the first electrode 10 and the electric conduction shielding layer 14, since the electric conduction shielding layer 14 is grounded to be zero potential. As a result, physiological electrical signals with different strength are output between the first extraction electrode 16 and the second extraction electrode 17. The second extraction electrode 17 is grounded (i.e. the electric conduction shielding layer 14 is grounded), by which the electric conduction shielding layer 14 is not only used as an output electrode of the physiological monitoring sensor strip described above, but also as a shielding layer with a better shielding effect after being grounded.
The electric conduction shielding layer 14 is a single-side adhesive conductive tape, fully wraps an outer surface of the insulation layer 18, and is in contact with the partial region of the second macromolecule polymer insulation layer 12. In the case that the insulation layer 18 is a single-side adhesive insulation tape, then its adhesive-side is attached to the first electrode 10, to the first macromolecule polymer insulation layer 11, and partially to the second macromolecule polymer insulation layer 12, an adhesive-side of the electric conduction shielding layer 14 is attached to the outer surface of the insulation layer 18 and a partial region of the second macromolecule polymer insulation layer 12 unwrapped by the insulation layer 18 so as to form a sealed-structure. In the case that the insulation layer 18 is a double-side adhesive insulation tape, is specific, a first adhesive-side of the insulation layer 18 (i.e. an inter surface of the insulation layer 18) is attached to the first electrode 10, to the first macromolecule polymer insulation layer 11, and partially to the second macromolecule polymer insulation layer 12, the adhesive-side of the electric conduction shielding layer 14 is attached to a second adhesive-side of the insulation layer 18 (i.e. the outer surface of the insulation layer 18) and the partial region of the second macromolecule polymer insulation layer 12 unwrapped by the insulation layer 18 so as to form the sealed-structure.
The sealed-structure formed by the second macromolecule polymer insulation layer 12, the insulation layer 18, and the electric conduction shielding layer 14, on the one hand, plays functions of waterproof and moistureproof, and thus omits a process of moistureproof treatment on outermost surface, on the other hand, achieves package of the first electrode 10, the first macromolecule polymer insulation layer 11, and the second macromolecule polymer insulation layer 12, and thus avoids the triboelectric electricity generation of the first macromolecule polymer insulation layer 11 and the second macromolecule polymer insulation layer 12 from being affected by the external environmental factors.
