A novel low-temperature printing method has been developed for creating wearable negative-temperature-coefficient thermistors on thermally sensitive fabrics. The method utilizes stable and printable ink to achieve a processing temperature of 120 degrees C.
A novel low-temperature route is developed for inkjet printing of the perovskite Cs2SnI6, to create wearable negative-temperature-coefficient thermistors with unprecedented performance on thermally sensitive fabrics. A low processing temperature of 120 degrees C is achieved by creating a stable and printable ink using binary metal iodide salts, which is thermally transformed into dense Cs(2)SnI(6)crystals after printing. The optimally printed Cs(2)SnI(6)shows a temperature measurement range up to 120 degrees C, high sensitivity (4400 K), and temperature coefficient of resistivity (0.05 degrees C-1), and stability under ambient environmental conditions and bending. The approach breaks a critical tradeoff that has hindered wearable fabric-based thermistors by enabling damage-free fabrication of devices with commercially comparable performance, evincing significant applications in multifunctional textiles and beyond.
