Wherein, the friction electrode sequence difference exists between the materials of the contact surfaces of the friction part and the conductive part.
According to the respiration monitoring device, the friction charge can be generated in the respiration process of a human body through the arrangement of the conductive part and the friction part, the electric signal representing the respiration condition can be determined according to the friction charge, an external power supply is not needed, the respiration condition of the human body can be monitored in real time, and the monitoring is timely and accurate.
Wherein, in order to improve the detection accuracy, the fixing part is arranged on the human body or clothes, in particular tight-fitting clothes, so that the conductive part and the friction part are relatively displaced along with the respiration of the human body. In addition, in order to further improve the strength of the friction electric signal, the contact surface of the friction component and/or the conductive component is provided with a nano-structure layer or a micro-structure layer.
As shown in fig. 1 to 4, the conductive member includes a first electrode layer 1 for generating triboelectric charges on the first electrode layer 1 during contact and separation with the frictional member.
Further, the conductive member further includes a first friction layer (not shown) disposed on the surface of the first electrode layer 1, and configured to generate friction charges when contacting and separating with the friction member, and to electrostatically induce charges on the first electrode layer 1.
As shown in fig. 4, the friction member includes a second friction layer 2, and when the second friction layer 2 and the conductive member are contacted and separated, friction charges are respectively generated on the second friction layer 2 and the conductive member, so that a friction potential difference representing a breathing condition is formed between the first electrode layer 1 and the ground. As shown in fig. 4, by arranging the first electrode layer 1 and the second friction layer 2, a single-electrode generator is formed, and the breathing condition of the human body can be determined according to the difference of the friction potential between the first electrode layer 1 and the ground. In the present embodiment, the first electrode layer 1 is made of a thin metal foil, and the second friction layer 2 is a polymer, but not limited thereto.
The material of the first friction layer and/or the second friction layer 2 may be at least one of polyimide, polytetrafluoroethylene, polyvinyl chloride, polychlorotrifluoroethylene, poly (propylene carbonate), polypropylene, polyethylene, polystyrene, polyvinylidene chloride, polyethylene terephthalate, polyvinyl alcohol, polymethyl methacrylate, polyurethane elastomer, polydiallyl phthalate, polyoxymethylene, etc. Wherein the width of the second friction layer 2 is 1-4cm, the length is 3-10cm, and the thickness can be in the order of several to tens of micrometers (mum).
Further, the friction component further includes a second electrode layer 3 (as shown in fig. 1 and fig. 3), disposed on a surface of the second friction layer 2, and configured to generate friction charges on the second friction layer 2 and generate induced charges on the second electrode layer 3, so that a friction potential difference representing a breathing condition is formed between the first electrode layer 1 and the second electrode layer 3. Through the arrangement of the first electrode layer 1 and the second electrode layer 3, different-sign friction charges are generated on the first electrode layer 1 and the second electrode layer 3, and further, electric signals between the first electrode layer 1 and the second electrode layer 3 are led out through wires 6 arranged on the first electrode layer 1 and the second electrode layer 3, so that the breathing condition of a human body is determined.
Wherein the thickness of the second electrode layer 3 is 50-200 nm. The material of the first electrode layer 1 and/or the second electrode layer 3 is a conductive metal alloy or a conductive metal oxide. The metal alloy may be at least one of gold, silver, platinum, aluminum, nickel, copper, iron, chromium, etc., and the metal oxide may be indium tin metal oxide, but not limited thereto.
Furthermore, the respiration monitoring device according to the invention comprises a substrate layer 5, which is applied to the skin or clothing, in particular tight-fitting clothing, of a person for supporting the friction or conductive means. Wherein the substrate layer 5 is made of a soft material. The spacing between the friction member and the conductive member may be on the order of tens to hundreds of microns when the friction member and the conductive member are separated.
Wherein, the base layer 5 is provided with a through hole 51 for passing any one of the fixing component, the friction component and the conductive component on the base layer 5, and in the process of breathing of a human body, the friction component and the conductive component have relative displacement so as to enable the friction component and the conductive component to be contacted or separated. The fixing member includes two binding bands 4 fixed to both ends of the friction member or the conductive member, respectively. Wherein the length of each binding band 4 is 5-55 cm.
As shown in fig. 1, when both the second friction layer 2 and the second electrode layer 3 of the friction member pass through the through hole 51 (only the second friction layer 2 or the second electrode layer 3 may pass through the through hole 51), the upper surface of the base layer 5 corresponds to the first electrode layer 1 on which the conductive member is disposed, but not limited thereto, and as shown in fig. 4, when the first electrode layer 1 of the conductive member passes through the through hole 51, the upper surface of the base layer 5 corresponds to the second friction layer 2 on which the friction member is disposed. When a human body breathes, the binding band 4 and the basal layer 5 respectively move, so that the friction part and the conductive part have relative displacement, and the friction part and the conductive part are continuously contacted and separated.
The operation of the respiration monitoring device of the present invention will now be described with reference to fig. 3.
In a normal state, the second friction layer 2 is separated from the first electrode layer 1, and then the charges on the second friction layer 2 and the first electrode layer 1 are in a balanced state; when a human body inhales air, the chest cavity and the abdominal cavity are expanded, the bandage 4 and the substrate layer 5 move respectively, so that the second friction layer 2 and the first electrode layer 1 generate relative displacement, the second friction layer 2 is in contact with the first electrode layer 1 and generates friction charges respectively, the charges on the second friction layer 2 enable the second electrode layer 3 to generate induction charges, the first electrode layer 1 and the second electrode layer 3 form a current loop through the lead 6, and an electric signal is output; when the inspiration of the human body reaches the limit, the contact area of the second friction layer 2 and the first electrode layer 1 is the largest, and the electric charge amount generated by friction is also the largest; when a human body exhales, the chest cavity and the abdominal cavity contract, the second friction layer 2 is gradually separated from the first electrode layer 1, and as the second friction layer 2 is a non-conductive organic thin film layer, equal amount of different-sign charges can be induced on the second electrode layer 3 in order to keep the electrical neutrality, so that electrons directionally move in an external circuit under the driving of potential difference and output an electrical signal; when expiration reaches the limit, the second friction layer 2 and the first electrode layer 1 are completely separated, and the generator is completely restored to the initial state.
