Outline of Research at the Start

本研究では、微小のエネルギーを環境発電により計測器に供給しつつ、計測対象の情報を取得するエネルギーハーベスティングセンサ構築を目的として、その基礎研究を実施する。提案するエネルギーハーベスティングセンサは以下の特徴を有する。

② 磁性体が形成する磁場の変化により誘導起電力が生じ、計測する
これらの特徴により、計測器が必要とする需要に即した電気を供給することができ、システム全体の効率的な運用が可能となると考える。これらの特徴を考察し、提案する新規エネルギーハーベスティングセンサ実現に向けてその有用性と、システム設計手法をまとめる。

Outline of Final Research Achievements

The possibility of integrating data acquisition sensors with a recently developed energy harvesting system that combines the magnetic phase transition and electromagnetic induction was investigated in this research.
Magnetothermal properties such as magnetic flux change throughout a magnetic phase transition were experimentally measured to examine characteristics that have strong implications for the proposed temperature sensor. The potential of changing the magnetic moment in a temperature sensor was evaluated. In addition, an appropriate magnetic material was searched and implemented to the proposed sensors.
These investigations demonstrate that the proposed system has great potential for application as an energy harvesting sensor.

Academic Significance and Societal Importance of the Research Achievements
