A fingertip-operated solid state capacitance switch detects a capacity change that is induced by the physical contact of an ungrounded fingertip to an external dielectric surface of the solid state switch. The input and output of a solid state signal-inverting amplifier are respectively connected to ...

Alan Henry Kramer: Two dimensional solid state capacitive sensor array. STMicroelectronics, Lisa K Jorgenson, Andre Szulwalski, January 4, 2005: US06839052 (27 worldwide citation)

An apparatus for providing an output signal for selectively controlling movement of a visual pointer on a display screen is disclosed. A plurality of solid state capacitive sensor switches are arranged in a two-dimensional array. Each of the switches is actuable in response to the positioning of a f ...
