With the flexibilization tendency of traditional electronics, developing sensing devices for the low-temperature field is demanding. Here, we fabricated a flexible copper-based thermistor by a laser direct writing process with Cu ion precursors. The copper-based thermistor performs with excellent temperature sensing ability and high stability under different environments. We discussed the effect of laser power on the temperature sensitivity of the copper-based thermistor, explained the sensing mechanism of the as-written copper-based films, and fabricated a temperature sensor array for realizing temperature management in a specific zone. All of the investigations have demonstrated that such copper-based thermistors can be used as candidate devices for low-temperature sensing fields.
随着传统电子产品的柔性化趋势，开发用于低温领域的传感设备变得很有必要。在此，我们通过使用铜离子前驱体的激光直写工艺制备了一种柔性铜基热敏电阻。该铜基热敏电阻在不同环境下具有出色的温度传感能力和高稳定性。我们讨论了激光功率对铜基热敏电阻温度灵敏度的影响，解释了所制备的铜基薄膜的传感机制，并制作了一个温度传感器阵列以实现特定区域的温度管理。所有这些研究都表明，这种铜基热敏电阻可作为低温传感领域的候选器件。
