A stretchable and transparent triboelectric nanogenerator based on prestretching PDMS with silver nanowires as electrode

Abstract

Compared with other mechanical energy collectors, triboelectric nanogenerators have the advantages of large output, high efficiency and good stability. However, they can produce stretching, twisting, bending in the process of collecting mechanical energy generated by human motion. Maintaining good stability under deformation becomes one of the great challenges of triboelectric nanogenerators. This work offers effective and simple method to fabricate a triboelectric nanogenerator that can work well under deformation. By spin-coating AgNWs on the pre-stretched PDMS surface to make a flexible electrode. Due to the materials used are silicone and silver nanowires, the device also has good transparency.
