A Compensator Microelectromechanical Acceleration Transducer with a Piezoelectric Sensing Element and Optical Reading
Introduction. Modern mobile control objects require the use of highly sensitive transducers of motion parameters, e.g., acceleration, with a wide measurement range. Increased sensitivity to measured parameters can be achieved by using precision optics, e.g., based on the tunneling effect. However, o...
