A flat, flexible foil makes the difference

The new sensor developed by Tech21 replaces the traditional key contacts of mobile electronic devices. Ordinary keys recognize only two states, on and off - whereas the Tech21 sensor measures the position and the applied force of a key activation steplessly.

With the Tech21 sensor keypads, joysticks, dials and sliders can be implemented even when very little space is available. During the integration process, Tech21 usability experts work closely with customers for best results.
