Nanogenerators harvest body’s energy to power devices
No need to plug in wearable or implantable gadgets that can perform medical tasks
POWER SQUEEZE With a squeeze, swing or jiggle, body motion can flex a triboelectric nanogenerator (left) to create voltage (right), which can charge implantable and wearable medical devices. Textured surfaces within the generator can boost the power output.
