ABSTRACT:
A capacitive position sensor employs conventional printed circuit board (PCB) technology to detect capacitive changes caused by the movement of a ball along conductive tracks. A recessed region (or through hole) is stamped on the PCB with well controlled dimensions. Electrically conductive tracks are laid around the region and connect to a capacitance detection circuit on the PCB. As the PCB experiences inclination or acceleration the ball moves along the axis of the recessed region causing variations in the measured capacitance.
