| Outline of Final Research Achievements |
Triboelectric charge has been known as electrostatic phenomena. But now, it is getting to be used as an electrical power source for a variety of applications. In this project, our group have challenged to evaluate the triboelectric charges as a power source, from dielectric physics viewpoint. Results showed that two microscopic origins, i.e., charge displacement and dipole rotation, are active in power generation process. Optical second-harmonic generation (SHG) microscope has been introduced as a new way to visualize these two origins selectively. The microscope is available to image a series of triboelectric charge generation processes in dielectric and insulating materials. In other words, dielectric and insulating materials are actively working as a power generation material.
