Touch Electronics


The sophistication of any touch system is its electronics and 3M Touch Systems has been developing electronics solutions since the mid-1980’s.

Surface capacitive sensing electronics are a core competency of 3M Touch Systems.

Product implementations:

Digital signal processing (DSP) algorithms are a core competency of 3M Touch Systems and 3M Dispersive Signal Technology (DST) uses these real-time DSP calculations to determine touch locations. The DST controller uses these advanced, proprietary algorithms to analyze the digital input provided by the piezo sensors.

Product implementations:
