Capacitive keyboards. The dynamic development of the electronic technology is undoubtedly a sign of our times. It results in the increasing use of capacitive keyboards. Products of this type are characterized by an interesting and modern solutions: multi-touch function, round adjuster, capacitive knob or slider are same of the important one. An additional advantage of it is a wide range of possible materials to be used as the front of the keyboard (glass, thick and cured polycarbonates, PMMA and standard polyester films). In designing capacitive keyboards, processors such as Atmel and Microchip are used.
