Triboelectric nanogenerators are devices that utilize the triboelectric effect combined with electrostatic induction to generate electricity. These devices are typically composed of two different materials that create a triboelectric charge upon contact. When these materials are periodically brought together and separated, an alternating current (AC) is produced. TENGs are especially useful for powering small-scale devices such as sensors and micro-electromechanical systems (MEMS).
