我们提出了一个全油漆过程，生产的呼吸传感器制成的湿敏纳米粒子（NP）薄膜和石墨痕迹。该传感器是在环境空气中制造的，采用简单的无真空工艺，适用于绿色电子产品：仅在醋酸纤维素薄膜上手工喷漆。在微量石墨电极上刷涂一层硅纳米粒子湿敏膜。使用该膜的全涂漆湿度传感器在10-93%的湿度变化内显示10（6）%的灵敏度。薄膜是柔性的，并且湿度传感器在弯曲测试后作为呼吸传感器操作。利用湿度传感器和涂敷电阻设计了一种全涂敷式呼吸传感器。最后，我们将全涂漆呼吸传感器、灵活的温度传感器和便携式数据记录器集成为便携式双功能医疗设备。该装置可以同时监测人的呼吸频率和呼出的空气温度。
We propose an all-painting process to produce a respiration sensor made from a humidity-sensitive nanoparticle (NP) film and a graphite trace. The sensor is fabricated under ambient air with a simple vacuum-free process for green electronics: solely hand-painting on a cellulose acetate film. A humidity-sensitive silica NP film is painted by brush on pencil-trace graphite electrodes. An all-painted humidity sensor using this film shows 10(6)% sensitivity within a 10-93% humidity change. The film is flexible and the humidity sensor operates as a respiration sensor after bending test. We design an all-painted respiration sensor using the humidity sensor and a painted resistor. Finally, we integrate the all-painted respiration sensor, a flexible temperature sensor, and a portable data logger as a portable bifunctional health-care device. The device on a mask can monitor human respiration rate and exhaled air temperature simultaneously.
