Triboelectric nanogenerator (TENG) is a clean energy, and has been spotlighted as the next generation energy using energy harvesting. Studies on polymer insulators having dielectric properties in TENG have been actively conducted, and based on charge series. However, recent studies have revealed phenomena that cannot be explained in series, such as charges generated even when the same materials are in contact with each other. Among the theory of contact electrification, the mass transfer theory recently shows the explanation of the charge between polymer insulators. So, people started making series based on specific parameters like modulus. Here, the PDMS was physically optimized for the charge density, and then, an empty space was provided in the structure to increase elongation and charge density.
