Copper capacitive sensors can be implemented on standard fr4 pcbs as well as on flexible material ito allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens) size and spacing of the capacitive sensor are both very important to the sensor's performance. The first part is the theory of capacitive touch detection in section 21, some basic terms are defined and discussed to give a basis for the description of capacitive touch detection provided in the equivalent circuit the second portion of the overview in section 22 introduces figures of merit used in capacitive touch detection. Capacitive touch sensor capacitive touch sensors are widely used in most of the portable devices like mobile phones and mp3 players capacitive touch sensors can be found even in home appliances, automotive and industrial applications the reasons for this development are durability, robustness, attractive product design and cost.
This breakout board is the simplest way to create a project with mutiple capacitive touch sensors no microcontroller is required here - just power with 18 to 55vdc and connect up to 5 conductive pads to the 5 left-hand pins.

Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, position and displacement, force, humidity, fluid level, and acceleration human interface devices based on capacitive sensing, such as trackpads ,  can replace the computer mouse.
This is a very cheap and easy project it gives a good idea of how capacitive touch works and how one can implement in several other applications this simple project uses a capacitive touch sensor, that switches on and off an led, or even high voltage appliances, by touching a piece of aluminium foil.
