MULTI-AXIAL FORCE SENSOR, METHOD OF MANUFACTURING THE MULTI-AXIAL FORCE SENSOR, AND METHOD FOR OPERATING THE MULTI-AXIAL FORCE SENSOR

A microelectromechanical transducer (1), comprising: a semiconductor body (2), having a first surface (2a) and a second surface (2b) opposite to one another; a plurality of trenches (4) extending in the semiconductor body (2) from the first surface (2a) towards the second surface (2b), including a first pair of trenches (4a) having a respective main direction of extension along a first axis (x), and a second pair of trenches (4b) having a respective main direction of extension along a second axis (y) orthogonal to the first axis; a first piezoresistive sensor (6a) and a second piezoresistive sensor (6b) extending at the first surface (2a) of the semiconductor body (2), respectively arranged between said first and second pair of trenches (4a, 4b), wherein the first piezoresistive sensor (6a), the second piezoresistive sensor (6b) and the plurality of trenches (4) form an active region (7a, 7b); and a first structural body (8), mechanically coupled to the first surface (2a) of the semiconductor body (2) in such a way to form a first sealed cavity (10) which encloses the active region.
