Abstract
Abstract
Magnetically controlled shape-memory alloys (MSMA) are smart materials with shape-memory function and such advantages, as large strain, high response speed and high energy conversion efficiency. This lucrative combination provides a theoretical basis for the design of MSMA sensor, which is also experimentally validated in this study. Based on the inverse effect of MSMA, the overall design of MSMA sensor is carried out. The structure of the sensor is optimized by finite element simulation. The input and output characteristics of the sensor are experimentally verified. Finally, the coil excitation power is reduced, and the output induction voltage of the sensor is increased. The correctness of sensor structure and rationality of optimization are verified.
