Nanointerface-Engineered Triboelectric Nanocomposite for Self-Powered Intelligent Motion Decoding

Real-time motion intelligence from wearable systems requires efficient conversion of biomechanical energy into stable and information-rich electrical signals. However, conventional triboelectric sensors often suffer from limited interfacial polarization efficiency and unstable output under complex mechanical deformation. Here, we present a self-powered triboelectric wristband enabled by nanointerface engineering to enhance mechanoelectric energy conversion and signal fidelity. The device integra
