Fabric Converts Kinetic Energy into Electric Power

A fabric was developed that converts kinetic energy into electric power. The greater the load applied to the textile and the wetter it becomes, the more electricity it generates. The woven fabric generates electricity when it is stretched or exposed to pressure. The fabric can currently generate...
