Abstract

Battery-Free Implants

In article number 2403712, Young-Jun Kim, Keren Dai, Sang-Woo Kim, and co-workers demonstrate the simultaneous transmission of acoustic power and precise acoustic information using a double-electrode triboelectric nanogenerator, enabling a battery-free implant controllable via ultrasound. A novel triboelectric membrane with a top electrode incorporating a gold-polymer intermixing layer has been designed to ensure sustainable power generation. Reversible micro-cracks form in the intermixing layer, maintaining electrical connectivity under high-frequency strain.
