Device for measuring force exerted on a measuring body
摘要
<p>The device has a surface wave sensor (1) provided with a piezoelectric substrate (2), where acousto-electric transducers (3) i.e. interdigital electrodes, are arranged on a surface of the substrate. The substrate of the surface wave sensor is pressurized with a uniaxial bias force in a main propagation direction (H) of surface waves by a biasing device. The biasing device is arranged in or at a measuring body such that force is transferred to the substrate along the biasing force of the biasing device. Clamping bodies are supported at the measuring body at surfaces of a cavity.</p>
