Decoupled temperature and moisture sensor made of CNT-based nanomaterials on flexible plastic substrates
In this paper, we report a successfully invented, prototyped, and characterized decoupled temperature and moisture sensor made of CNT-based nanomaterials on flexible plastic substrates. The detailed design of sensing elements, electronics hardware, and software are presented here. We tested the humidity sensor in constant temperature and in increasing temperature modes in a Espec BTL-433 humidity chamber. The measured results were compared to those collected by an Omega RHT HX71 series sensor. We discovered that our sensor can measure humidity independently of temperature, and it can also detect moisture from human breath. Preliminary results of temperature sensing are also presented.
