摘要
通过水热法制备了MoS_2和TiO_2,采用层层自组装制作电容型薄膜湿敏传感器,在11%~97%RH湿度范围内的测试结果表明其灵敏度高达150 270%,而且具有快速响应及恢复特性。采用STM32、结合LabVIEW进行了硬件电路设计以及程序编写,实现了湿度测量和人体呼吸频率的监控,构建了人机界面友好的实验测试平台。
MoS2 and TiO2 are prepared by the hydrothermal method.By using the capacitive thin film humidity sensor fabricated by the layer self-assembly,the test results in the humidity range of 11%—97% RH show that the sensitivity is up to 150 270%,and it has the characteristics of the fast response and recovery.The related hardware circuit design and programming are carried out.By using STM32 and in combination with LabVIEW,the humidity measurement and the monitoring of human respiratory frequency are realized,and a friendly experimental testing platform with the human-computer interface is established.
