This paper presents the inkjet-printed flexible temperature and humidity sensor(F-TH sensor) using PEDOT:PSS. The series, meshand parallel type sensing element using PEDOT:PSS ink was printed on the overhead projector(OHP) film. The fabricated sensor ofeach structure has the temperature sensitivity of 140 Ω/oC, 29 Ω/oC and 1.4 Ω/oC with linearity, respectively. Also the fabricated sensorwas not only possible to measure a temperature, but also to detect humidity. The humidity sensitivity of 400 Ω/%RH, 3.4 Ω/%RH and3 Ω/%RH with linearity, respectively. The fabricated F-TH sensor is expected for the various applications such as electronic devices,bio-healthcare, industrial field.
