▎ 摘　　要

Transient power sources with excellent biocompat-ibility and bioresorablility have attracted significant attention.Here, we report high-performance, transient glucose enzymaticbiofuel cells (TEBFCs) based on the laser-induced graphene(LIG)/gold nanoparticles (Au NPs) composite electrodes. SuchLIG electrodes can be easily fabricated from polyimide (PI) withan infrared CO2laser and exhibit a low impedance (16 Omega). Theresulted TEBFC yields a high open circuit potential (OCP) of 0.77V and a maximum power density of 483.1 mu W/cm2. The TEBFCnot only exhibits a quick response time that enables reaching themaximum OCP within 1 min but also owns a long lifetime over 28days in vitro. The excellent biocompatibility and transientperformance fromin vitroandin vivotests allow long-termimplantation of TEBFCs in rats for energy harvesting. The TEBFCs with advanced processing methods provide a promising powersolution for transient electronics.
