Triboelectric nanogenerators (TENGs) are promising energy conversion devices that transduces mechanical energy into electrical energy based on contact electrification and the electrostatic effect. For practical electronics sensor applications, the high output performance of the TENG's is required. The output performance of the TENG is dependent on the surface area and type of contact material. Therefore, development of the surface structure that has large surface area is an encouraging way to improve the output performance of TENG. In this work, we fabricated highly sensitive TENG based on microporous-micropatterned Poly(dimethylsiloxane) (PDMS). We fabricated TENG with various micro-pattern, micro-pore size, and the density of micro-pore using Si mold and polystyrene (PS) microsphere. The patterned PDMS morphology has been investigated through scanning electron microscopy (SEM). The electrical output performance of the TENGs was measured under various compressive force and frequency. |
