The intrinsically stretchable triboelectric nanogenerators (TENGs) suffer from poor performance. To address the challenge, an international team of researchers (China, USA – the Pennsylvania State University) has developed a fully stretchable TENG consisting of an intrinsically stretchable MXene/silicone elastomer and silver nanowires (Ag NWs)-graphene foam nanocomposite. The TENG exhibited high output performance (voltage, current, and power), long-term reliability, and stable electrical output under various extreme deformation conditions. It harvested the intermittent mechanical energy from human bodies to charge various energy storage units such as commercial capacitors for driving wearable electronic devices. They demonstrated the systems in applications from home anti-theft to water resources early warning systems, which provided the proof-of-the-concept demonstrations for the next-generation standalone device platforms…read more.
