Abstract: In one aspect the invention provides an electromechanical device having a conductive component which is stretchable and having a conductive lead to connect the component to an electrical circuit. The conductive lead may be arranged as threaded through the component at multiple locations on the component layer to integrate the lead with the component. Aspects provide a laminated capacitor formed of elastic material with first and second elastic electrode layers. The conductive lead may comprises an inner conductor and an outer conductor arranged to cover the inner conductor. A length of exposed inner conductor is arranged threaded through the first component and an exposed length the outer conductor is arranged threaded through the second conductive component.

Abstract: In one aspect the invention provides an electrical sensor having an electrical capacitance which varies with mechanical deformation to allow instrumenting of deformation by a connected electric circuit, the sensor comprising conductive material separated by dielectric material and operable to deform and change in capacitance with deformation of the capacitor, the capacitor arranged to have a structure of a twisted plane wherein the capacitor is supported in that arrangement by support material.
