One embodiment of a surface force distribution sensor includes an elastic dielectric (108) sandwiched by a first plurality of compliant, conductive carrier elements (110) and a second plurality of conductive pickup elements (106), as well as a system for frequency-domain demultiplexing including at least a microprocessor (209). A plurality of signals is generated, each of which has a different fundamental frequency and is connected to a different carrier element. The pickup and carrier elements are arranged so that each pickup element overlaps one or more carrier elements. When forces are applied to a nonconductive compliant layer (112), the distance between one or more carrier elements and one or more pickup elements decreases at their points of overlap, increasing the amplitude of carrier signals capacitively transmitted to the pickup elements. The microprocessor demultiplexes the signals received from the pickup elements to determine the amplitude of each carrier signal received, and thereby the applied force, at each point of overlap on the surface of the compliant layer. Other embodiments are described and shown.
