Abstract
A force sensor having a substrate for measuring forces is provided, on which substrate a first path and a second path for travel of acoustic surface waves are arranged. The two paths are arranged essentially parallel to one another and their lengths are different. An effect of a force on the substrate is detectable by measuring a time needed for an acoustic surface wave to travel at least one of the first and second paths.
