  • Patent number: 9927311
    Abstract: A high-sensitivity sensor containing cracks is provided. The high-sensitivity sensor is obtained by forming microcracks on a conductive thin film, which is formed on top of a support, wherein the microcracks form a micro joining structure in which the microcracks are electrically changed, short-circuited or open, thereby converting external stimuli into electric signals by generating a change in a resistance value. The high-sensitivity sensor can be useful in a displacement sensor, a pressure sensor, a vibration sensor, artificial skin, a voice recognition system, and the like.

  • Patent number: 9893367
    Abstract: Provided is an interlayer for a thin electrolyte solid oxide cell, a thin electrolyte solid oxide cell including the same, and a method of forming the same. In various embodiments, functional elements (a fuel electrode, an electrolyte and a cathode) of the solid oxide cell are formed by means of a thin film process, and thus a nanostructure of the catalyst is not seriously lost due to agglomeration, different from a powder process. Thus, it is possible to accomplish catalyst activation according to a high specific surface area.
