Fast charging self-powered wearable and flexible asymmetric supercapacitor power cell with fish swim bladder as an efficient natural bio-piezoelectric separator

A fast and self-charging all-solid-state asymmetric supercapacitor power cell (SCASC) is fabricated employing the dual functionality of fish swim bladder as natural separator and bio-piezoelectric nanogenerator. The flexible SCASC can be efficaciously charged either electrically or by applying mechanical deformations. Eight serially connected SCASC can power-up several portable electronic gadgets and LEDs upon repeated finger imparting.487
