Measuring sensor for simultaneously measuring forces that can be dynamic or static

摘要

The present invention relates to a measuring sensor (1) for simultaneously measuring a force (F) which can be dynamic or static, comprising at least one piezoelectric sensing element (10, 10 ′), The force (F) of the sensing element (10, 10 ′) against the element surface generates a polarization charge, and the magnitude of the generated polarization charge is at least one piezoelectric sensing element ( 10, 10 ') and a resonating element (20) which can be excited at at least one resonance frequency (f), wherein the force (F) is such that the piezoelectric sensing element (10, 10') and the resonance A resonant element (20) acting on the element (20), wherein the force (F) causes a lateral extension (Q) of the resonant element (20) and the lateral extension (Q) ) Occurs laterally, and the lateral direction differs from zero with respect to the direction of force The magnitude of the lateral extension (Q) is proportional to the magnitude of the force (F), and the lateral extension causes a frequency change (Δf) of the resonance frequency (f), and the frequency change is It concerns a measuring sensor (1) which is a function of the force (F).
