Abstract: Described herein is a ruggedized microelectromechanical (“MEMS”) force sensor. The sensor employs piezoresistive or piezoelectric sensing elements for force sensing where the force is converted to strain and converted to electrical signal. In one aspect, both the piezoresistive and the piezoelectric sensing elements are formed on one substrate and later bonded to another substrate on which the integrated circuitry is formed. In another aspet, the piezoelectric sensing element is formed on one substrate and later bonded to another substrate on which both the piezoresistive sensing element and the integrated circuitry are formed.
