    Abstract: A spacer layer (7) with a cavity (8) etched out therein and a diaphragm (2) arranged thereabove on the spacer layer are located on a silicon substrate (1) with a doped region (5) formed therein, whereby the doped region and the diaphragm are electrically connected via terminal contacts (4, 6) to electronic components (13) that are likewise integrated in the substrate (1). The electronic component are a component part of the operating circuit that can also be used for the drive of the diaphragm and for evaluating the diaphragm oscillations. The integration makes it possible to arrange the micromachined transducer components as array that can be electronically driven as phased array.

    Abstract: A grid-shaped array of conductor areas is used for capacitive image acquisition. Shielding conductors are disposed in each case between the conductors that are provided for measurement. During a plurality of charging and discharging cycles, the potential is always carried along on the conductors belonging to a respective pixel in order to prevent displacement currents between the shielding capacitors. By way of example, a compensation line with a feedback operational amplifier can be used for identically altering the electrical potentials on the conductors.
