Wearable and flexible electrodes in nanogenerators for energy harvesting, tactile sensors, and electronic textiles: novel materials, recent advances, and future perspectives

There are numerous drivers in the context of sustainable energy production from ambient mechanical energy sources, such as body motions, due to the increasing world demand for alternative energy. Recent progress has been made in the energy harvesting technologies based on piezoelectric nanogenerators (PENGs) and triboelectric nanogenerators (TENGs) to convert such ambient biomechanical energy into electricity. The PENGs and TENGs technologies …
