Development on a measuring system of driving force of wheelchair using a giant magnetostrictive material

Abstract

A prototype of driving force measurement system for wheelchair was developed and tested, using the giant magnetostrictive material. In the preceding research, such measurement system using a magnetostrictive torque sensor had been developed, but its excessive width and weight may affect the measurement results. To solve this problem, the measurement system using the giant magnetostrictive material was developed. The width was same as the original wheel and the weight became a half of it, and measurement of driving force and velocity was confirmed.
