In this paper an array of frequency selective capacitive vibration sensors with electrically tuneable band selectivity is presented. The band selectivity is based on the resonance characteristics of the structures, the centre frequency of which is tuned by electrostatic forces directly applied to the seismic mass. The eight-cell array fabricated in surface near silicon bulk micro-technology (SCREAM) covers the frequency range from 1 to 10 kHz. Measurement results illustrate the tuning characteristics of the array and the linearity of the capacitive comb structures. Furthermore the functionality of the micro-system consisting of the sensor array, analogue signal detection circuitry and an eight-bit micro-controller for array control and signal evaluation tasks is described.
