As manifold as the application fields for capacitive touch sensors, are the technical solutions.
It is possible to implement a touch sensor in software with a Microcontroller together with some external components. The other end of the range is defined by fully integrated hardware products. All methods detect the change of capacitance, if an electrode is touched by a human finger.
Though this principle is the same for all methods, every approach feature specific advantages and drawbacks.
The paper presents various capacitive sensing approaches and discusses the properties current consumption, response time, cost and reliability of these methods.
An important aspect of touch user interfaces is reliable and robust operation. Since environmental parameters like humidity and temperature can influence the sensor behavior, it might be necessary to compensate these factors. Otherwise the system might become instable and false touches are detected. Methods to overcome this problem in actual applications will be presented in the paper. Since more and more applications feature a display, touch sensors in combination with screens are discussed in a third part of the paper. If the sensing electrodes are transparent, they can be placed
onto a display and the user is able to control a device by pressing virtual buttons directly on the screen. Capacitive touch screens offer some advantages compared to resistive solutions which are very common in the industry and widely used already.
