The present disclosure provides electrical field ("E-field") sensor systems that sense displacement or change in displacement of one body relative to another. In general, the bodies 110, 112 are within an electrical field and displacement of a body causes a change in the E-field. A field sensor 290 detects this change and a processor 275 translates it to a change in position of the displaced body 110 . The E-fields are generated by electrodes (or an electrode and a ground member) that generate the E-field. The systems include detectors 240 that detect changes in the E-field, such as capacitance, and transmit these to the processor 275.
