The development of polymer thermistors is attracting attention because they have several advantages including flexibility, conformability and biocompatibility. However, most polymer thermistors containing a high concentration of opaque filler materials still have issues such as low sensitivity, optical transparency and operational durability due to low electrical conductivity and inefficient hopping transport. Here, a highly sensitive and transparent polymer thermistor using silver fractal dendrites (AgFDs) and a polyacrylate has been demonstrated. It exhibits a superior positive temperature coefficient intensity (~107) because of the high electrical conductivity of the AgFDs and the quantum tunneling effect resulting from their unique structures. Moreover, it exhibits excellent optical transparency, mechanical flexibility, and operational durability. Based on these characteristics, the thermistor was successfully demonstrated for real-time temperature monitoring of human body. |
