Actuator device for electro-hydraulic system of e.g. airplane, has piezoresistive transducers that detect force received or delivered by actuator and transmit output signal to control unit that controls actuator based on output signal

摘要

The device has a control unit (11) connected with an actuator, for supplying a control signal and controlling the output range of force and/or path of the actuator. The piezoresistive transducers (9) connected with control unit, detect the force received or delivered by the actuator and transmit output signal to the control unit. The control unit controls the actuator based on the output signal. The piezoresistive transducer layer is formed with undoped hydrocarbon or pure carbon. An independent claim is included for method for controlling actuator device.
