The invention relates to a flexible capacitive sensor fabricated by employing a silver
nanowire flexible
electrode. The flexible capacitive sensor comprises an upper-layer flexible
electrode plate, alower-layer flexible
electrode plate and an intermediate flexible
dielectric layer, wherein each flexible electrode comprises a flexible substrate, a silver
nanowire electrode thin film layer, and thesilver
nanowire electrode thin film layer is arranged in the flexible substrate. A fabrication method of the electrode employs a
transfer printing method, the silver nanowire electrode thin film layer is fabricated in an electrode template, a flexible
polymer is injected for curing, so that the silver nanowire conductive thin film layer is transferred to the flexible substrate. The flexible
dielectric layer is divided into two types comprising a thin
film structure and a porous structure, the thin
film structure is fabricated by uniformly
coating a flexible
polymer prepolymer on a
silicon wafer to form a
thin layer, the porous structure is fabricated by a template method, the flexible
polymer prepolymer is uniformly mixed with salt, a film formation structure is fabricated and cured, andthe porous
dielectric layer structure is obtained after salt removal. The flexible capacitive sensor is simple in fabrication method and has favorable
signal response.
