摘要：Bending actuators are key elements in many application fields. This paper presents an InkJet Printed actuator embedding an electromagnetic driving mechanism and a resistive sensing strategy. The lateral actuation range of the device is in the order of few millimeters, while it can exert forces in the order up to 375 µN. A deep characterization of the device is presented which reveals good performance of the lab-scale prototype developed both in the static and dynamic regime. In particular, the responsivity is found to be a function of the magnetic field used to actuate the beam. Specifically, responsivities of 43.5 × 10−3 m/A, 28.3 × 10−3 m/A and 19.5 × 10−3 m/A have been estimated in the static condition in the case of magnetic fields of 98.8 mT, 70.6 mT and 37.1 mT, respectively, while at the resonance frequency of 4.1 Hz the responsivity is 51 × 10−3 m/A in case of a magnetic field of 37.1 mT.
