Abstract

The tunnel effect acceleration sensor has a mass part (4) movable at springs (5) fashioned in a sensor layer (1), particularly a monocrystalline silicon layer of an SOI substrate. A tunnel electrode (6) and a cooperating electrode (7) are arranged lying opposite one another in the plane of this sensor layer (1). One of these electrodes (6,7) is attached to the mass part (4) and one is firmly connected to the substrate. Compensation electrodes (8,9) are present for the electrostatic positioning of the mass part (4).
