a Schematic image of the textile-based BFC module composed of eight BOx-based cathodes and two LOx-based anodes connected by printed flexible interconnections. b A zoomed-in photo image of the fabricated BFC module. Scale bar, 5 mm. c The charge generation mechanism of the BFC from lactate and oxygen in sweats. d The output power of the BFC module at different discharge potentials with 15 mM lactate concentration. e The equivalent polarization curve derived from (d). f The output power of the BFC module discharged at 0.5 V under various lactate concentrations. g Image of the BFC module under 180° outward bending. Scale bar, 1 cm. h The power of the BFC module before and after the 1000 bending cycles. i The output power of the BFC module with 10 mM lactate concentration everyday within a week.
