ABSTRACT:
A dynamic grip sensor is formed from a unitary block having upper and lower covers. The sensor, being of a size so that it can be gripped by a human hand, comprises two sets of parallel flexure beams connected between outer end blocks and a center block and are loaded by a base plate connected to the outer end block and extending between the end blocks. The flexure beams deflect to respond to hand grip strength. Strain sensors located on the flexure beams and connected in a wheatstone bridge provide indication of gripping strength. The grip sensor may operate apart from a supporting structure or be incorporated into a handle or similar structure.
