Patent ID: 7381223

Claim:
A prosthesis comprising: a unitary body, comprising: a first plate; a second plate spaced apart from a side of the first plate to form a gap therebetween such that forces placed upon the second plate are isolated from the first plate; a lower plate having a first flexure and a second flexure positioned therein, the lower plate being spaced apart from a bottom of the first plate and a bottom of the second plate; a first support post aligned with the first flexure and connecting the bottom of the first plate with a top of the lower plate such that forces placed upon the first plate are transmitted to the first flexure; a second support post aligned with the second flexure and connecting the bottom of the second plate with the top of the lower plate such that forces placed upon the second plate are transmitted to the second flexure; and a plurality of force sensors provided in the first and second flexures to sense strain therein.
