| 发明名称 | Surface area-based pressure sensing | ||
| 摘要 | Various aspects of the instant disclosure relate to pressure sensing methods and apparatuses. As may be implemented in accordance with one or more embodiments, an apparatus includes a plurality of structures having respective surface areas that are implemented to contact at least one of an electrode and other ones of the structures. The structures operate with the electrode to provide an electrical indication of pressure by effecting a change in the respective surface areas in response to an elastic compression or expansion of the structures, and providing a change in electrical impedance between the structures and the electrode based on the change in the respective surface areas. | ||
