The system uses a self-voltage-regulated wearable microgrid based on enzymatic biofuel cells and AgCl-Zn batteries to harvest and store bioenergy from sweat, respectively. It relies on osmosis to continuously supply sweat to the sensor array for on-demand multi-metabolite sensing and is combined with low-power electronics for signal acquisition

In both applications with different modes of operation, the wearable microgrid system—with its complementary and synergistic BFC-TEG harvesting and commensurate SC pairing—was able to deliver both fast-booting and extended-harvesting to ensure the autonomous and sustainable operation of the wearable platforms.
Inspired by this notion, we herein propose and demonstrate the concept of a wearable e-textile microgrid system: a multi-module, textile-base system with applications powered by complementary and synergistic energy harvesters and commensurate energy storage modules.
In summary, we have demonstrated the concept of wearable bioenergy microgrid via a textile-based multi-module system for sequentially harvesting biomechanical and biochemical energy via the TEG and BFC modules.
For wearable microgrid testing, data were sampled by the fPCB and transmitted to a laptop or smartphone wirelessly via Bluetooth at a sampling interval of 30 s and a transmit interval of 5 min. Further information on research design is available in the Nature Portfolio Reporting Summary linked to this article.
Viewing the scattered wearable energy technologies through the concept of independent microgrids allows us to reassess the goal of establishing a reliable, practical, and energy-economical wearable system.
The fingertip-wearable microgrid system consists of four BFCs, two AgCl-Zn batteries, a flexible printed circuit board (fPCB), four potentiometric electrochemical sensors and a hydrogel-based osmotic sweat pumping system with a laser-engraved paper microfluidic channel (Fig. 1a).
