A touch sensor is provided. The touch sensor includes at least two capacitive sensing electrodes, each of the at least two capacitive sensing electrodes having a surface area that is smaller than an area of a touch from a user. The at least two capacitive sensing electrodes each include a substrate, a single conductive element formed on the substrate, and electronic circuitry coupled to the at least two capacitive sensing electrodes for measuring a self-capacitance of the at least two capacitive sensing electrodes. A position corresponding to the touch of a user is determined by the electronic circuitry based on a difference of the measured self-capacitance between the at least two capacitive sensing electrodes.
