Outline of Final Research Achievements

Transparent pyroelectric organic infrared sensors were fabricated and characterized the device structure for high voltage sensitivity. Transparent device ; ITO/P(VDF/TrFE)/ITO could be operated as pyroelectric infrared sensor. By using Free-standing P(VDF/TrFE) thin films as pyroelectric layer, the voltage sensitivity increased, because of the lower heat capacity. In addition, with increasing ITO film thickness, the voltage sensitivity increased owing to improvement of absorption of infrared radiation.
