Mechanical apparatus includes a base, a moving element, and a hinge, having a first end attached to the moving element. A supporting structure is attached to the base and to the second end of the hinge and has at least a component perpendicular to the hinge so as to translate rotation of the moving element about the hinge into elongation of the component, whereby the moving element rotates about the hinge relative to the base while the supporting structure is deformed as a result of the rotation of the moving element about the hinge. A strain-based rotation sensor is associated with the supporting structure and is configured to provide a signal indicative of the rotation of the moving element responsively to a strain induced due to deformation of the supporting structure as the result of the rotation of the moving element. |
