Patent ID: 7710371

Claim:
A cell comprising: part of a support structure that has a support surface; an adhesion structure that is on the support surface; a flexible structure that includes a polymer layer coated over the support surface; the adhesion structure attaching the polymer layer to the support surface in a first region and not attaching the polymer layer to the support surface in a second region surrounded by the first region; the flexible structure, when unstretched, lying in a flat position with its lower side directly on the support surface in the second region; in response to stretching force away from the support surface in the second region, the flexible structure moving out of the flat position to provide a variable volume between the flexible structure and the support surface in the second region; one or more electrodes; charge levels on the electrodes coupling with the variable volume and providing the stretching force; the electrodes including a lower electrode at the support surface; and signal circuitry that provides a signal path between at least one of the electrodes and external circuitry; the adhesion structure including at least one of: a patterned layer of adhesion promoter; the adhesion promoter being present in the first region and not present in the second region; a patterned layer of fluorocarbon material; the fluorocarbon material being present in the second region and not present in the first region; a patterned layer of inorganic material that adheres to the polymer layer; the inorganic material being present in the first region and not present in the second region; and a patterned layer of exposed ultraviolet light absorbing material and an adhesion promoter over the ultraviolet light absorbing material; the ultraviolet light absorbing material being present in the second region and not present in the first region; the support structure including: a substrate; an insulating layer that includes the support surface, the support surface being disposed away from the substrate; a device layer between the substrate and the insulating layer; and interconnecting material providing a conductive path from the lower electrode at the support surface through the insulating layer to the device layer; the signal circuitry providing the signal path through the interconnecting material and through the device layer.
