First Claim
Patent Images
1. A device with piezoresistive detection, comprising at least:
- a proof body on which an effort to be measured is exerted,means of detecting a strain exerted by the proof body under the action of the effort, comprising at least one suspended piezoresistive strain gauge,a strain amplifier cell comprising at least two rigid arms mechanically linked to each other by at least one link element at the level of a first of their ends, a second end of a first of the two rigid arms being mechanically linked to the proof body, a second end of a second of the two rigid arms being fixed to a substrate, the link element being mechanically linked to a first end of the suspended piezoresistive strain gauge.
