ABSTRACT: Practice makes perfect to some extent. Researchhas shown that musicians who practice the piano for long peri-ods of time can suffer a range of hand problems from loss ofcontrol to diminished speed. Now imagine a rubber keyboardthat is springy, soft, and elastic. This is the new type of inputdevice that dielectric elastomers (DE) can create. However theirusage in large sensing systems is limited by a scalability chal-lenge. Each DE sensor is married to a pair of connection cablesand electronics, adding to the complexity of the backgroundoverheads. A new efficient multi-frequency method is pre-sented that is capable of detecting internal pressure changesfrom a difference in the DE’s capacitance without the need forany additional wires or connections. This effectively segmentsthe DE into smaller sections, achieving information from a sin-gle sensor equivalent to multiple sensors. V C 2015 Wiley Period-icals, Inc. J. Polym. Sci., Part B: Polym.
