PolyTC
Touch keys are electronic switching devices with no moving parts, which are operated by finger touch. The switching process is triggered while touching a surface, for example, by a change in capacitance.
Under the brand name PolyTC, PolyIC produces transparent conductive films with which you can achieve flat touch keys as controls.
This capacitive sensor buttons as controls, based on PolyTC films, have the following advantages:
■transparent / invisible
■backlit
■thin and flexible
■high conductivity
■ready for integration
■individually structurable - custom layout possible
■available on roll
■large quantities available
■flat capacitive touch buttons possible to achieve controls
■sensor with wiring can be produced in one process
■modern design / extravagant button design feasible
