A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

Wearable Battery‐Free Electrotherapy of Smartsensors for Wound Healthcare

Advanced Science, EarlyView.
Herein, we propose a simple strategy for integrating battery‐free electrotherapy wound dressings with wound sensors. Solid‐state supercapacitors constructed by PMAB with cross‐linked interpenetrating network provide energy for electrotherapy. Meanwhile, excellent mechanical sensing performance of wound dressing was used for wound assessment.
