  • Patent number: 10139338
    Abstract: Provided is an electromechanical transducer having a reduced unnecessary signal and improved acoustic characteristics. The electromechanical transducer includes an element. The element includes a plurality of cells that are two-dimensionally arranged and electrically connected. Each of the cells includes: a first electrode; and a vibrating film including a second electrode, the second electrode being opposed to the first electrode with a gap interposed therebetween. The cells are arranged so that, when center portions of the plurality of cells are connected by straight lines in all combinations, one of outermost straight lines and another of the outermost straight lines are non-parallel with each other or different in length of parallel portions.
    Type: Grant

  • Patent number: 8334497
    Abstract: An image sensor includes a pixel array with a plurality of pixels, wherein each of the plurality of pixels includes: a photoelectric conversion unit; and a waveguide structure in which a side face of a substance that has a higher refractive index than a refractive index of a plurality of insulation films is surrounded by the plurality of insulation films so that light is guided to the photoelectric conversion unit, and wherein an insulation film that surrounds a region where the light is concentrated of the side face of the substance has the lowest refractive index among the plurality of insulation films.
