Title:
COMPOSITE FILM, SENSOR ELEMENT COMPRISING SAID COMPOSITE FILM, BODY FAT PERCENTAGE MEASURING DEVICE, AND ELECTROCHEMICAL CELL DEVICE, AND WEARABLE MEASURING DEVICE COMPRISING SAID SENSOR ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/034857
Kind Code:
A1
Abstract:
Provided are: a composite film which has stable electrical conductivity, mechanical strength, and flexibility not readily affected by moisture, and in which position aberration or peeling can be prevented when the composite film is used in close contact with a body to be contacted; a sensor element comprising the composite film, a body fat percentage measuring device, and an electrochemical cell device; and a wearable measuring device comprising the sensor element. A composite film including electroconductive nanoparticles and nanofibers, the nanofibers having a plurality of gaps therebetween that are communicated with the outside, the electroconductive nanoparticles adhering to the surface of the nanofibers and being present in the plurality of gaps, the nanofibers being hydrophilic and biocompatible, and the composite film being electroconductive and being used in close contact with a body to be contacted that is hydrophilic-treated or that contains moisture.
