The first multifunctional elastic (>650％) fiber that can scavenge biomechanical energy and electromagnetic energy from surrounding electrical appliances is developed as a wearable power provider and various self-powered sensors. These findings optimally unify mechanical freedom and the capability of harvesting biomechanical energy and electromagnetic energy from surrounding electrical appliances as well as self-powered sensing in a single fiber.
This is the first energy-harvesting fiber that simultaneously possesses inherent elasticity (> 650％ strain) and the ability to harvest biomechanical energy and electromagnetic energy from surrounding electrical appliances for wearable electronics and active sensing uses. Particularly, this is the first report that a fiber can convert dielectric-loss energy from surrounding electric/electronic appliances to available energy of wearable gadgets. The achieving stretchability also sets a new record high in energy-harvesting fibers.
Wearable and stretchable electronics are attracting immense interest. This is the first energy-harvesting and self-powered sensing fiber that simultaneously possesses inherent elasticity (> 650％ strain) and the ability to harvest biomechanical energy and electromagnetic energy from surrounding electrical appliances. The new advancements in stretchable/wearable energy and sensing technologies can advance a wide range of emerging wearable technologies, personal electronics, smart clothing, and sensing technologies
