In order to develop smart sensor network, the electronic sensors must be low-cost and flexible to enable widespread distribution. To meet those criteria, we have demonstrated a temperature sensing tag fabricated by all-additive solution processes. The sensor tag is consisted of a printed thermistor bridge, a threshold control circuit, and non-volatile memories. The threshold control circuit is based on organic complementary thin-film transistors operating at supply voltage of 20V, and the non-volatile memories are capacitors with ferroelectric polymer dielectric. When the thermistor temperature exceeds a pre-set threshold, the control circuit is triggered to generate a pulse to write into the memory. This temperature sensor tag is self-contained and will be applicable to packaging or environmental monitoring applications. In addition to demonstrating the tag performance, we will discuss our approach to tackle the challenges of device variations and stability in printed devices.
