Abstract:
A method of making acceleration sensors with integrated measurement of internal pressure includes connecting multiple plates to each other, thereby defining internal cavities. The tightness of these connections or bonds is checked and controlled during the manufacturing process. The plates define membrane portions adjacent each cavity, the membranes deforming in accordance with the internal pressure in the adjacent cavity. Preferably, the internal pressure of the sensor is measurable by detecting deformation of a sensor wall which defines a membrane.
