ThruMode Matrix Array

This array of 160 force sensing cells, 10 rows and 16 columns, allows the user to simultaneously measure force of every cell at once. With an active area of 2"x3" this pad can be used as a multi-touch user input device, a musical controller, or even to measure the force distribution of objects.

ThruMode construction allows measurement of low force values.
