Magnetostrictive bioinspired whisker is a new kind of sensor that can realize tactile and flow sensing by utilizing magnetoelastic\neffect. The sensitivity is a key technical indicator of whisker sensor. The paper presented a new magnetostrictive whisker based on\nGalfenol cantilever beam, as well as its operation principle. Then, the static and dynamic sensitivity of the whisker sensor was\ninvestigated by using a self-made experimental system. The results illustrated that the proposed sensor has a high sensitivity. Its\nstatic sensitivity is 2.2 mV/mN. However, its dynamic sensitivity depends on the vibration frequency. When working at the natural\nfrequency of the cantilever beam, the dynamic sensitivity performs an obvious increaseââ?¬â?1.3mV/mN at 3.5 Hz (the first-order\nnatural frequency) and 2.1mV/mN at 40 Hz (the second-order natural frequency), respectively.
