Most of the human bodys touch sensors react when applying pressure to the skin. TheCapacitive touch sensor, however, has few drawbacks such as there could be a false trigger since all it needs is to be in a contact with a conducting material and does not require a pressure to operate. c) A microcontroller picks up the change in capacitance and converts it into an input signal. When the switch pad is left untouched, then the potential difference between the emitter and the collector will be 12V and the potential difference between the emitter and the base will be zero (this I admit is debatable), since the base is not connected anywhere, which means the difference of potential between the base and the collector is 12V in a direction that reverse biases the collector-base junction. Commonly used in kiosks or gaming applications, infrared touch sensors are long-lasting and insensitive to pressure (similar to capacitive touch sensor). Capacitive screens can detect multiple fingers at once, making them better suited for large tablets or touchscreen devices that need to support multi-touch gestures like zooming and scrolling.
