The tunneling transducer measures variations in a quantum mechanical tunneling currentbetween the moving membrane and a fixed conducting tip. The device is operated in a force rebalance mode, which maintains the electron tunneling distance and thus keeps the current constant, using simple feedback electronics. Once assembled and packaged, the detector is very robust and can withstand high levels of mechanical shock without degradation in its performance. Benefits Miniaturized detector allows compact instrumentation to be designed and fabricated. Detector does not require cooling or temperature stabilization.
Detector is mechanically obust, has low-power operation, and uses drive and readout circuitry.
