Capacitive Touch Sensor Design
The process for designing products that use touch controls is a complex process with many decisions to
be made, such as what materials will be used in their construction and how the mechanical and electrical
requirements will be met. The key to this process is the design of the actual sensors (specifically buttons,
sliders, wheels and touch screens) that form the interface with the user. This application note covers self-capacitance sensors, touch cover effect, shielding, mutual capacitance sensors, sensor design, and touch cover effects.
