An e-textile walking step counting full system (smart T-shirt) is presented. Harvesting from co-designed low-voltage triboelectric nanogenerator (TENG) pushes over-voltage protection/rectification on chip. Conformability and minimal
off-chip components are achieved via dual-function harvester/sensor reuse and battery/passive elimination.
Always-on power reduction to pWs enables uninterrupted operation while solely powered by breathing harvesting.
