  • Patent number: 10555790
    Abstract: Methods of manufacturing a flexible force sensor include forming a first sensor part providing a plurality of spaced first electrode plates in an electrically non-conductive material. A second sensor part is also formed and includes a plurality of second electrode plates in an electrically non-conductive material. The second electrode plates are identical to the first electrode plates at least in terms of spacing. The first part is assembled to the second part such that each of the first electrode plates are aligned with and parallel to, yet spaced from, respective ones of the second electrode plates, establishing a plurality of capacitive sensing components. The first electrode plates are movable relative to the corresponding second electrode plates, establishing a variable gap therebetween. The sensor parts can be ring-shaped. The sensor parts can be formed via MEMS techniques, with the non-conductive material being a polymer.

  • Patent number: 7995777
    Abstract: A thin film acoustic transducer is formed with an electrically actuatable substantially transparent thin film. Substantially transparent conductive thin films are supported on both sides of the electrically actuatable substantially transparent thin film. The thin film transducer may be used to sense sound, or produce sound in various embodiments. In further embodiments, the film may be attached to a window, and operate as a speaker for an audio system, or may provide noise cancellation functions. In further embodiments, the film may be attached to a computer monitor, touch panel, poster, or other surface, and operate as a speaker. A method of forming carbon nanotube thin films uses a layer by layer assembly technique and a positively charged hydrophilic layer on a thin film substrate.
