摘要：

In this paper we present the development of enhanced printed temperature sensors on large area flexible substrates. The process flow is a fully screen printed technology that uses exclusively solution-processed materials. These Screen printed temperature sensors are based on resistive pastes integrated in a Wheatstone bridge circuit. Substrate is a commercial Poly Ethylene Naphtalate (PEN) with a thickness of 125 mu m. Functional temperature sensors are demonstrated and characterized with good electrical properties, showing a good sensitivity of 0.06 V/degrees C at V-in = 4.8 V. This sensitivity is enhanced by the annealing and the O-2 plasma treatment. Based on this temperature sensor, we have developed a demonstrator for human body temperature detection.
