Temperature sensors have attracted great attention for personal health care and disease diagnosis in recent years. However, it is still a great challenge to fabricate reliable and highly sensitive temperature sensors that can convert physiological signals into easily readable signals in a convenient way. Herein, an integrated smart temperature sensor system based on a traditional temperature sensor and electrochromic display is proposed for real-time visual detection of temperature. Significantly, a voltage-regulated electrochromic device (ECD) based on tungsten oxide (WO) and polyaniline (PANI) as the real-time visualization window was integrated into the platform to provide feedback on the temperature change. The ECD would change its color from green to blue based on the electrical signal of the temperature sensor, resulting in a visualized readout that can be monitored through our naked eye. Additionally, the smart temperature sensor system possesses an extremely durable property and cycle stability, remaining around 90% of the initial value even after 15,000 s continuous cycle. Thus, the novel design and low power consumption advantages make it a good candidate to pave the way for developing interactive wearable electronics and intelligent robots as real-time temperature feedback systems.
近年来，温度传感器在个人医疗保健和疾病诊断方面备受关注。然而，制造出可靠且高灵敏度的温度传感器，能够以便捷的方式将生理信号转换为易于读取的信号，仍然是一项巨大的挑战。在此，提出了一种基于传统温度传感器和电致变色显示器的集成智能温度传感器系统，用于实时可视化温度检测。值得注意的是，基于氧化钨（WO）和聚苯胺（PANI）的电压调节电致变色器件（ECD）作为实时可视化窗口被集成到该平台中，以提供温度变化的反馈。ECD会根据温度传感器的电信号从绿色变为蓝色，从而产生一个可通过肉眼监测的可视化读数。此外，该智能温度传感器系统具有极其耐用的特性和循环稳定性，即使在连续循环15000秒后仍保持初始值的约90%。因此，这种新颖的设计和低功耗优势使其成为开发交互式可穿戴电子设备和智能机器人作为实时温度反馈系统的理想候选者。
