Sensors are widely used for various applications for the sensation of physical, chemical, optical, thermal, and electrical signals. Although numerous inorganic and metallic sensors have been commercialized for practical applications, organic sensors based on organic electronics have not attracted much attention to date. Considering the features of organic electronics such as softness, flexibility, lightweight, ultra-tenuity etc, the targets of organic sensors should be wisely chosen. Recently our group attempted to develop ultrasensitive tactile sensory devices by employing organic field-effect transistors (OFETs) and liquid crystals (LCs). In this presentation we show recent results on the LC-on-OFET sensory devices and discuss the working mechanism for ultrasensitive sensing. |
