Powering LEDs with movement

摘要

With the rise of IoT applications and devices, there's growing demand for portable energy sources to power them. Energy harvesting is a very popular method - from solar power, thermal energy and mechanical friction, among many other sources. Triboelectric nanogenerators (TENGs) harness mechanical motion, but they are prone to surface damage from friction. To avoid such damage, triboelectric materials and liquids are used.
