Abstract (en)

[origin: EP1516595A1] Device for measuring the pressure between two bodies pressed against each other has at least an oscillator (1) with at least an induction coil (2), a sensor (11) made from at least partially conducting material that is arranged around the coil and an evaluation circuit (14) for determining the frequency change resulting from changes in the inductance of the induction coil caused by changes in the pressure applied to the sensor. The invention also relates to a corresponding use of the inventive device for determining the dental contact pressure or occlusion pressure between teeth.
