  • Surface area-based pressure sensing
    Patent number: 9453774
    Abstract: 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.

  • STRETCHABLE DEVICE, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC APPARATUS INCLUDING STRETCHABLE DEVICE
    Publication number: 20150280129
    Abstract: Provided are stretchable devices, methods of manufacturing the same, and electronic apparatuses including the stretchable devices. A stretchable device may include first and second material layers, each including an elastomeric polymer, and an organic layer that is disposed between the first and second material layers. The organic layer may include an organic semiconductor. As least one electrode element may be embedded in at least one of the first and second material layers. The at least one electrode element may be electrically connected to the organic layer. The stretchable device may be stretchable in a direction parallel to the organic layer. The stretchable device may be a transistor, and may further include a gate electrode.
