Patent ID: 7690272

Claim:
A micro-sensor, comprising: a fixed reference frame; an elastic pivot with at least two co-axial segments of pivot and coupled to the fixed reference frame and having a neutral axis that is a central line of the pivot, a moveable body coupled to the elastic pivot and the reference frame, the moveable body and the reference frame sharing a reference surface, the moveable body extending between the two co-axial segments to provide that for a rotation of the moveable body about the pivot the moveable body approaches the reference surface at a first side and recedes from the reference surface from an opposite side and provide an opening gap and a closing gap, the neutral axis being below the reference surface; at least a first gauge configured to detect tilt about the elastic pivot and measure separation of the moveable body and the reference frame at the reference surface, the gauge providing a measurement of the opening and closing of the opening and closing gaps; and wherein inputs to be measured cause the moveable body to rotate about the pivot and strain the gauge.
