The following are some excerpt from the pap:

Proximity capacitive sensing is a technology that enables touch detection by measuring capacitance, exhibiting a change in capacitance in response to a change in surrounding materials. Certain sensors gauge the change by generating an electric field (e-field) and measuring the attenuations suffered by this field. Unlike inductive sensors, a proximity capacitive sensor can detect anything that is either conductive or has different dielectric properties than the sensor’s electrodes’ surroundings. They are excellent touchpad enablers because we, humans, being mostly water, have a high dielectric constant, and we contain ionic matter, which makes us good electric conductors.
