Claim Text:
1. A micromechanical structure having a first axis of symmetry, the micromechanical structure comprising: a semiconductor substrate; a stator structure that is fixed with respect to said substrate and includes fixed sensing electrodes; a rotor structure including a suspended mass elastically coupled to a suspension body, the suspended mass being mobile with respect to said substrate and to said stator structure in response to an external acceleration, the suspension body fixed to said substrate, said fixed sensing electrodes being capacitively coupled to said rotor structure; and a compensation structure configured to compensate for thermo-mechanical strains that occur within said mircomechanical structure, said compensation structure including stator compensation electrodes that are fixed with respect to said substrate and are capacitively coupled to said rotor structure, the stator compensation electrodes being distinct from the fixed sensing electrodes, the stator compensation electrodes being symmetrically arranged relative to said fixed sensing electrodes with respect to the first axis of symmetry, the first axis of symmetry extending along a longitudinal axis of the suspension body.
