Facile fabrication of flexible and adhesive micro-supercapacitor tapes from conducting polymer solution for self-powered wearable sensing system

Flexible micro-supercapacitor (MSC) with in-plane electrodes has attracted significant attention as microscale energy storage device. Especially, flexible MSCs adhesion properties are of great interest for wearable electronics. Here, we demonstrate a facile and cost-effective mask-assisted drop-casting method to fabricate adhesive MSC on medical tape using dimethyl sulfoxide (DMSO) doped poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) aqueous solution. The fabricated (vinyl alcohol)/H 3 PO 4 gel electrolyte exhibits an areal specific capacitance 10.96 mF cm −2 at current density 0.1 mA excellent mechanical flexibility. can be attached various substrates due the stickiness tape. For practical application, coupled solar cell achieve stand-alone power supply system flex senor in monitoring finger movements. Therefore, believe that paves new way develop self-powered integrated
