PCT No. PCT/DE95/01048 Sec. 371 Date Feb. 11, 1997 Sec. 102(e) Date Feb. 11, 1997 PCT Filed Aug. 9, 1995 PCT Pub. No. WO96/05491 PCT Pub. Date Feb. 22, 1996The force or extension sensor has a measuring capacitor (Mk) whose comb-like, interlocking electrode structures (Es1, Es2) can be adjusted in parallel with one another by two attachment points (Bp1, Bp2) as a function of the force (F) or the extension (E) to be measured. The total capacitance of the measuring capacitor (Mk) is determined by a parallel circuit having individual electrode pairs. A change in the total capacitance of the measuring capacitor (Mk) which is brought about by a change in the distances (d1) between the electrodes provides information on the force (F) or the extension ( epsilon ) to be measured. A change in the distances between the electrodes as a result of temperature-related extension is at least largely avoided by virtue of the fact that the attachment points (Bp1, Bp2) lie on a junction line (V1) which runs parallel to the direction of the electrodes (E1, E2) and is oriented at an angle ( alpha ) of 40 DEG to 50 DEG , preferably 45 DEG , with respect to the direction of the force (F) or the extension ( epsilon ) to be measured.
