    Abstract: An active micro-force sensor is provided for use on a micromanipulation device. The active micro-force sensor includes a cantilever structure having an actuator layer of piezoelectric material and a sensing layer of piezoelectric material bonded together. When an external force is exerted on the sensor, the sensor deforms and an applied force signal is recorded by the sensing layer. The applied force signal is then fed back to the actuating layer of the sensor via a servoed transfer function or servo controller, so that a counteracting deformation can be generated by the bending moment from the servoed actuating layer to quickly balance the deformation caused by the external micro-force. Once balanced, the sensor beam comes back to straight status and the tip will remain in its equilibrium position, thus the sensor stiffness seems to be virtually improved so that the accurate motion control of the sensor tip can be reached, especially, at the same time, the micro-force can also be obtained by solving the counteracting balance voltage applied to the actuating layer.

    Abstract: A piezoelectric sensor system according to the invention employs a piezoelectric actuator relay (20) having a piezoelectric element displaceable in response to an actuation voltage and contacts (23, 24) which open or close in accordance with the displacement of the element, wherein the actuator relay (20) is adapted to receive a force (L) to be measured against the displacement. This piezoelectric actuator relay (20) is supplied, by a driver circuit (60), with a varying voltage as the actuation voltage. The relation between the forces (L) and the activation voltages necessary for opening or closing the contacts (23, 24) has been stored in a memory (70). A processor (50) obtains a value of the force (L) based on a value of the actuation voltage at the instant of the opening or closure of the contacts (23, 24) and the relation stored in the memory (70).

    Abstract: An instrumentation system for use in measuring and processing industrial process variables, such as flow, pressure, or temperature, includes a resonant element sensor whose resonant frequency varies in accordance with changes in the desired process variable communicating through an optical fiber link to a distant control room. The sensor is activated into resonant physical motion by light energy from a source in the control room, while the motion of the wire is sensed optically and retransmitted to the control room to produce an output signal whose frequency is equal to that of the resonating element. A feedback network maintains the sensor in resonance by synchronizing the delivery of light energy to the motion of the resonant element. The powering and sensing aspect may be performed by individual fiber optic cables or alternatively this function may be combined by utilizing a single fiber optic strand.
