Liquid metal electrode makes superstretchy nanogenerator

Wearable electronics such as activity trackers and biometric sensors demand power sources that can bend and flex as the body moves. Researchers have developed a triboelectric nanogenerator—which scavenges energy from static electricity produced during motion—using an electrode made from a liquid gallium, indium, and tin alloy. The device retains its function even when bent in half or stretched to three times its length.
