技術說明

目前光學接近感測器大部分由無機分子為材料，其製程困難，且不容易製作於可撓式基板上，若要應用於大面積感測時(如機器人的皮膚)，要一顆一顆嵌入，成本相當高。相對於此，有機分子具有可撓性，可製作於大面積軟性基板而應用於任合表面，其製程簡單並有低成本的潛力。但有機分子因材料特性，發光及吸光範圍大多為可見光波段，此波段進行接近感測時可偵測距離相當短。以紅外光製作光學接近感測器較不易被散射，偵測距離也較遠，而紅外有機發光二極體非常少見，固本創作研發紅外光之光學接近感測器可同時具有偵測距離較長即可製作於大面積可撓式基板之優點。 Most commercial proximity sensors are made of inorganic materials with complicate fabrication process and not easy to be used on flexible substrate. It will cost very much when applied in large-area substrate (like the skin of robots). On the contrary, it is easy for organic materials to be applied in large-area and flexible substrate due to their mechanic property. The organic materials have potential for easy fabrication process and low cost. However the emission and absorption range of organic materials are about the visible range. In the visible range the sensing distance is very short (1cm). For proximity sensor the infrared light is commonly used due to the longer sensing distance. It is difficult for organic materials to emit or absorb infrared light. Our invention is to make a infrared organic proximity sensor through a color-conversion film. It has the advantages for both long sensing distance and large-area as well as flexible application.
