QTC Multi-force Matrix Sensors provide true pressure sensing feedback as well as position information. As force is applied to the individual sensels in the electrode array, the resistance output drops at each touch point.
A pressure map can then be plotted for the whole sensor. Multiple touch point positions and pressure can then be interpolated and palm rejection is also possible.
The rows/columns in the matrix are continuously scanned to sense multiple force touches simultaneously – providing true 3D next generation multi-force data.
