Abstract:
1. A micromechanical component, comprising: a holder; an adjustable element connected to the holder via at least a spring; a first sensor device having at least one first piezo-resistive sensor element, the first sensor device being configured to provide a first sensor signal relating to a first mechanical stress acting on the at least one first piezo-resistive sensor element, and the first piezo-resistive sensor element being disposed at least one of (i) on or in a first anchoring region of the spring, which first anchoring region is adjacent to the holder, and (ii) on or in a second anchoring region of the spring, which second anchoring region is adjacent to the adjustable element; and a second sensor device having at least one second piezo-resistive sensor element, the second sensor device being configured to provide a second sensor signal relating to a second mechanical stress acting on the at least one second piezo-resistive sensor element, and the second piezo-resistive sensor element being disposed at least one of (i) on or in the first anchoring region of the spring, and (ii) on or in the second anchoring region of the spring; wherein the spring is patterned out of a monocrystalline silicon material, and wherein the longitudinal direction of the spring is one of oriented along the 110 crystal direction or oriented along the 100 crystal direction of the monocrystalline silicon material.
