Abstract
A transducer includes a plurality of electrodes and a dielectric shuttle. The dielectric shuttle passes between a subset of the electrodes, modifying the capacitance between them. By measuring the capacitance of subsets of the electrodes, the position of the dielectric shuttle may be determined.
