Abstract: Yarn energy harvesters containing conducing nanomaterials (such as carbon nanotube (CNT) yarn harvesters) that electrochemically convert tensile or torsional mechanical energy into electrical energy. Stretched coiled yarns can generate 250 W/kg of peak electrical power when cycled up to 24 Hz, and can generate up to 41.2 J/kg of electrical energy per mechanical cycle. Unlike for other harvesters, torsional rotation produces both tensile and torsional energy harvesting and no bias voltage is required, even when electrochemically operating in salt water. Since homochiral and heterochiral coiled harvester yarns provide oppositely directed potential changes when stretched, both contribute to output power in a dual-electrode yarn.
