Electret is a dielectric, of which electric charge is permanently hold. Electrostatic induction power generation using electret has excellent characteristics especially in small scale, low frequency environmental vibration power generation. In this research, based on innovative electret materials and liquid crystals for power generation, which we have been studying so far, new manufacturing technology for mounting these materials on the high-output-power energy harvester will be developed for wearable devices. In addition, standard evaluation method will be developed for power generation prediction in order to facilitate social implementation of such energy harvester.

We develop a new technology to realize an autonomous microelectronics chip that drives itself by the electrical power ranging from 10 µW to 100 µW retrieved within a chip from the environmental vibrations of around 100 Hz and 0.1 G through the hybrid/monolithic integration of MEMS (microelectromechanical systems) vibrational energy harvesters with microelectronic circuits.

We investigate phonon engineering, which enables advanced thermal management in solid, and contribute to the development of thermal conduction control technology by nanostructures using ballisticity and wave nature of thermal phonons. We also develop thermoelectric material with low environmental load based on phonon engineering and contribute to build up smart community by realization of sensing systems powered by thermoelectric energy harvesters in an academia-industry framework.

This project aims to combine two striking mechanisms we discovered to enhance thermoelectric properties. Namely, utilizing magnetism (i.e. magnetic interaction and spin fluctuation) for enhancement effective at relatively high temperatures, and also enhancement via novel nanostructuring, thereby, developing high performance magnetic semiconductor thermoelectric materials and devices, which can serve as replacement to Bi2Te3-type materials and modules for cooling, and realise application of power generation.

A new scaling strategy has emerged for the thermoeletric energy harvester. The power density of the planar-type thermoelectric generator is found to be improved by miniaturization and integration, similar to Si-LSI techology. This project focused on the demonstration of the Si-based thermoelectric generator, and its development using a carbon nanotube sheet, aimed at applications in wareable devices and forthcoming IoT technlogies.
