Continuous touch positioning and trajectory tracking are essential for immersive human-machine interaction, yet conventional interfaces are fundamentally limited by rigid power supplies and tethered data transmission. Here, we present a completely self-powered, finger-worn interface that wirelessly transmits spatial tr...

The human body continuously generates weak, broadband acoustic–mechanical signals that encode rich cardiopulmonary information, yet their reliable capture in real-world settings remains constrained by motion artifacts, limited bandwidth, and suboptimal mechanical coupling. Here, we present a wearable, wireless stethosc...
