摘要：
The idea of the resonant-antiresonant method is used to design new touch sensors based on amorphous wires. Ultrasonic resonant vibrations of the wire which is fixed at one end or in the middle of its length are excited by ac magnetic field due to magnetoelastic properties of the wire. Changes of impedance or permeability resulting from applied stresses are detected. The main advantages of the sensor are: low cost, security, high sensitivity, small cross-section, fast frequency response and a large temperature range of operation.
