Wearable thermoelectric devices, capable of converting body heat into electrical energy, provide the potential driving power for Internet Things, artificial intelligence, and soft robotics. However, critical parameters have long been overlooked these practical applications. Here, we report a three-dimensional flexible device with structure featuring an inner rigid outer woven design. Such includes numerous small static air pockets that create stable out-of-plane temperature difference, enabling precise signal detection (accuracy up to 0.02 K). Particularly, this exhibits excellent multi-signal decoupling capability, elasticity (>10,000 compression cycles), ultra-fast response (20 ms), output under 50% compressive strain, high breathability (1300 mm s−1), washability. All metrics achieve highest values currently reported, fully meeting requirements moisture exchange, as demonstrated in our designed integrated smart mask glove systems based on vector machine learning technology.
