Surface Engineering for Enhanced Triboelectric Nanogenerator

Triboelectric nanogenerator (TENG) is the new technique that can convert low-frequency mechanical energy into effective electricity. As an collector, pursuit of high output characteristics understandable. Although charge density has been achieved by working in vacuum or pumping techniques, it remains challenging to obtain performance directly atmosphere. Herein, surface-engineering triboelectric layer for enhancing reviewed carefully. By constructing surface morphology developing modification, TENGs finally presented review.
