Abstract
A micromechanical resonant vibration sensor (MRVS) is presented with a geometrical structure that is designed for the detection of vibration s in the low-frequency range. The MRVS is distinguished from conventio nal piezoelectric and micromechanical acceleration sensors by the util ization of the resonance effect. The signal-to-noise ratio increases s ignificantly when the sensor is excited with the designed frequencies. The vibrational properties of the MRVS have been investigated in the laboratory. Examples of the sensor response to different vibrational s ources are analysed under industrial conditions. The capability of the sensor principle for wear monitoring is discussed.
