Abstract
A conductive structure is used in electric variable resistance devices to provide changes in electrical resistance with movement and changes in pressure, the variable resistance device comprising externally connectable electrodes (10) bridged by an element (14) containing polymer and particles of metal, alloy or reduced metal oxide, said element (14) having a first level of conductance when quiescent and being convertible to a second level of conductance by change of stress applied by stretching or compression or electric field, the device further comprising by means (18) to stress the element (14) over a cross-sectional area proportional to the level of conductance required.
