PROBLEM TO BE SOLVED: To provide an MHD sensor/actuator for generating torque and sensing the angular displacement around a sense/torque axis. SOLUTION: A column of conductive liquid, which rotates within a circumferential channel, having an inner circumferential surface and outer circumferential surface, provides an inertial proof mass, and the relative motion of the inertial proof mass within the channel generates a torque around the common axis of the circumferential channel. The actuator/sensor 100 is provided with an insulating inner cylinder 102, having a cylindrical axis 110 arranged along the sense/force-generating axis of the actuator/sensor 100. In this way, magnetic field is generated in the direction of the common axis. COPYRIGHT: (C)2007,JPO&INPIT
