Smart Materials for Vibration

Professor, Faculty of Engineering

MURASAWA Go

There are materials that not only deform when force is applied but also change the surrounding magnetic field, generate electricity, or return to their original shape when heated after deformation. Such materials, which express special functions in addition to deforming when force is applied, are called Smart Materials. Murasawa Laboratory is dedicated to the creation and evaluation of smart materials specialized for vibrational phenomena, as described.

(1) Development of mechanical materials that not only absorb vibrations like rubber but also are as heat-resistant and strong as metals (bell structure materials).

(2) Development of mechanical parts that generate electricity through vibration (magnetostrictive composite materials).

(3) Development of next-generation energy harvesting technology that can convert all surrounding vibrations into electricity (printed piezoelectric polymer materials).
