Force Sensor Design

Lowcost point contact force sensors (FSS1500NST? , Honeywell Inc.) are used to build the force plate. They are embedded in a cast urethane plate. To improve accuracy and make the fingertip force sensor less sensitive to the point of application of the contact force, the signals from three point-contact sensors are summed to obtain the resultant force on the plate.

From the above picture you can see that three sensors are held in the base plate. (sensors are not wired in this figure to show a clear layout)
