    摘要： A system-integrated motion sensor is provided for monitoring and adjusting EVF system. The motion sensor is based on the concept that, with the aid of electrodes (4,5) that are already present and which are used for the viscosity control of the EVF in a hydraulic system, an electric current signal is simultaneously produced which is directly related to the rate of flow of the EVF between the electrodes. The electrodes are either stationary or can be displaced with respect to each other. Thus the motion sensor consists of the electrodes with the intermediate EVF layer and a circuit connected to the electrodes for measuring the electric signal produced by the motion. The measured signal thus obtained can advantageously be used for adjusting or controlling the viscosity of the EVF layer. For this purpose the measured signal is compared with a preadjusted value and the difference is used for controlling a high-voltage device which provides an output voltage dependent on the control voltage. This output voltage is fed back to the electrodes of the EVF layer and in turn influences the viscosity. Thus the measuring sensor for the motion, that is the EVF layer together with the associated electrodes, simultaneously forms the regulating unit for controlling the motion.
