Abstract

This paper presents the design, simulation and characterization of magnetostrictive sensors manufactured in several geometric shapes aiming at the high sensitivity with less amount of material. The experimental results showed that the smaller sensor with only 0.1 g of Terfenol-D achieved the highest sensitivity.
