Dr. Yoshiyuki Kawazoe is a Professor and Professor Emeritus in New Industry Creation Hatchery Center, Tohoku University, Sendai, Japan. On 11 October 2017, Prof. Kawazoe gave a talk on Magnetostriction Power Generation – Energy Harvesting Material for IoT System without Battery.  He proposed magnetostriction material for electric energy conversion. The first magnetostriction material was proposed by the US Naval Research Laboratory; GaFe, galfenol, which is a multi-crystal and less efficient than the existing piezoelectric material. Prof. Kawazoe presented ways to make it better by (1) single crystal growth, (2) theoretical prediction and realization of ternary materials, and (3) new efficient systems. He also introduced such history of energy harvesting materials and its present status. There were about 20 Students and 5 faculty members attended the seminar.
