A8.3 - A Novel Magneto–Elastic Force Sensor Design Based On Terfenol–D

Klaus Oppermann & Bernhard G. Zagar
In this paper the magneto–elastic–effect is taken under further investigation, to determine the utility of the novel material Terfenol–D in force sensor applications. By the reason that Terfenol–D has one of the largest magnetostrictive constant known we anticipated to get a higher sensitivity of the force sensor as compared to other materials e. g. steel. A simple and robust single coil sensor set-up is introduced. The dependency on the characteristic parameter of this set-up the...
