摘要： Provided is a high-sensitivity sensor having a conductive thin film containing linearly induced cracks. The high-sensitivity sensor relates to a sensor, obtained by forming linearly induced microcracks on a conductive thin film formed on a support, for measuring external tensile and pressure by measuring a change in the electrical resistance due to modification, short-circuiting, or openings in micro-joining structures formed by the microcracks. The high-sensitivity conductive crack sensor may be applied to high-precision measurements or artificial skins, and may be utilized as a positioning detection sensor by pixelating the sensor. Thus, the high-sensitivity sensor may be effectively used in the fields of precise measurements, bio-measurement devices through human skin, human motion measuring sensors, display panel sensors, etc.

摘要： 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.

摘要： An organic photovoltaic cell is provided. The organic photovoltaic cell includes a first electrode layer formed on a substrate, metal nanoparticles bound to the surface of the first electrode layer, a hole transport layer formed on the metal nanoparticles to form a nano-bump structure together with the metal nanoparticles, a photoactive layer formed on the hole transport layer, and a second electrode layer formed on the photoactive layer. The nano-bump structure enhances plasmonic effects, leading to an increase in photocurrent. The photoactive layer has an uneven structure. This uneven structure allows the photoactive layer to absorb larger amount of light than an even structure does, leading to an improvement in the photovoltaic efficiency of the organic photovoltaic cell. In addition, the nano-bump structure can be formed by simple dry aerosol deposition without involving a complicated exposure or transfer process, contributing to a marked improvement in economic efficiency.
