Design of a New Piezoelectric Force Sensor

In this paper (Part 1), new utilization of piezoelectric materials for development of a force sensor is presented. Measurement of force in certain point is done by transferring it through incompressible fluid to the piezoelectric layer assembled in a designed structure. The new structure used changes the locally imposed force to equally distributed hydrostatic pressure on the piezoelectric layer. This produces unique stress in the layer and the result is a measurable proportional voltage to generated strain. The sensitivity, durability and measurement range of the new sensor has been investigated by numerical simulations, which shows promising space for industrial progress.
