Magnetic Force Enhanced Sustainability and Power of Cam-Based Triboelectric Nanogenerator

Since the first invention of triboelectric nanogenerators (TENGs) in 2012, many mechanical systems have been applied to operate TENGs, but mechanical contact losses such as friction and noise are still big obstacles for improving their output performance and sustainability. Here, we report on a magn...
