Incentive Optimization Design of GMI Sensors

Abstract

.With the advantages of high sensitivity, good reliability, small size and being good at resisting bad environment, GMI sensors are potential in applications of engineering. Generally speaking, incentive scheme of GMI sensors determines whether the GMI effect can be generated sufficiently, which may have an important effect on the sensors sensitivity and measurement range. The paper analyses current GMI sensors incentive scheme, then proposes two incentive optimization designs. The schemes can fully generate non-magnetic materials GMI effect. Meanwhile, performance of the sensor can be greatly improved.
