Abstract
An apparatus comprising an array of electrical conductors connected to circuitry that determines data indicative of objects at particular locations based on capacitance at junctions of conductors in the array. The apparatus comprises a first set of conductors arranged on a first substrate and a second set of conductors arranged on a second substrate to form an array. The first and second substrates are separated by an air gap within which the electrical conductors are positioned. Each conductor may be independently addressable, having a proximal end connected to readout electronics and a distal end that is not. The apparatus may be cut, at the ends distal to where the conductors connect to the circuitry, to fit a desired location, such as on a store shelf, while remaining operational.
