Wearable Rehabilitation Devices Using Textile‐Integrated Triboelectric and Piezoelectric Nanogenerators

Wearable rehabilitation technologies increasingly integrate triboelectric (TENG) and piezoelectric (PENG) nanogenerators into textile architectures to create self‐powered, flexible, body‐conformal devices with improved mechanical compliance, biocompatibility, and clinical usability. Here, we critically examine TENG, PENG, and hybrid TENG–PENG technologies from a rehabilitation‐focused, textile‐integrated perspective. Specifically, we compare material systems, fiber‐, yarn‐, and fabric‐level fabrication strategies, and device architectures, and discuss their integration into wearable platforms for self‐powered motion sensing and energy harvesting to support therapeutic feedback. These advances suggest a promising pathway toward next‐generation wearable rehabilitation platforms that combine energy harvesting, real‐time sensing, and therapeutic feedback within everyday garments, potentially improving patient outcomes through continuous, autonomous monitoring and intervention.
