| 研究実績の概要 |
This research aims to create a novel field that converts the indoor ambient thermal variations into electrical energy. The core technology (thermoelectric generator (TEG)) and basic technology (phase change material (PCM)) are combined to convert the indoor ambient temperature fluctuations into usable electricity as a power source for wireless IoT sensing system. The temperature difference of 0.1oC to 1.0oC is always available (anytime and everywhere) due to temperature changes (between day and night) or air convections (wind, humidity,…), biological heat (people walk near the system) across the TEG by employing PCM which is converted into electricity as an electrical power source for wireless IoT systems. The success of the proposal would open a new scenario of “free from energy” for IoT sensing systems. It means that the energy can be harvested at anytime and anywhere from the ambient temperature fluctuations which can accumulate and store for sensing system.

理由
I'm currently focused on improving thermoelectric materials and refining the fabrication process of thermoelectric generators. I have successfully developed high-performance n-type thermoelectric materials using Bi2Te3 as a base. Our efforts are now directed towards optimizing the p-type thermoelectric material.

| 今後の研究の推進方策 |
I plan to develop high-performance p-type thermoelectric materials using an electrodeposition method. Through doping ions or embedding nanoparticles into the composite, we anticipate enhancing performance by leveraging the phonon-scattering effect. Additionally, I will utilize micro-fabrication technologies to fabricate micro-thermoelectric generators.
