▎ 摘　　要

NOVELTY - Porous three-dimensional electrode comprises a conductive layer, a solid contact conductive layer combined on any surface of the conductive layer, and an ion selective film layer combined on the surface of a solid conductive sheets away from the conductivity layer, where the solid contact conductor layer has a 3D porous structure and a hydrophobic nature. USE - Porous three-dimensional electrode for use in wearable real-time sweat detecting sensor (claimed). Uses include but are not limited to watch, wristband, patch, textile, glass, glove, optical lens and tooth protecting sleeve. ADVANTAGE - The electrode material of the wearable real-time sweat detecting sensor can effectively reduce the formation of the water layer and promote the ion to the electron transduction process, so that the sweat sensor has high sensitivity and long-term stability. The ion-electron transduction layer of the porous three-dimensional electrode formed by combining the ion selective film layer is completely based on double-layer capacitance effect, and is good for improving the contact area of the interface and the chemical adsorption of the carrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of the porous three-dimensional electrode.
