Abstract

In this paper authors examine the design and implementation of a cantilever beam-style probe for non-contacting electrostatic voltmeter. The beam is driven by a piezoelectric actuator with a feedback loop controlling amplitude of the electrostatic sensor displacement. Choice of the vibration mode and placement of the actuator and sensor are discussed. A simple model for the first three natural frequencies of the beam is constructed and compared with the experimental results.
