supercapacitor–biofuel cell (SC–BFC) system. The hybrid device, screen-printed on both
sides of the fabric, is designed to scavenge biochemical energy from the wearer's sweat
using the BFC module and to store it in the SC module for subsequent use. The BFC relies
on lactate, which is oxidized enzymatically to generate electricity. The generated bioenergy
is stored directly and rapidly in the printed in-plane SCs. The SC energy-storage module …
