Characteristics analysis and Fabrication of Integrated Piezoresistive Temperature & Humidity Sensors
A self-sustained multi-sensor platform for indoor environmental monitoring is proposed in this paper. To reduce the cost and power consumption of the sensing platform, in the developed platform, organic materials of PEDOT:PSS and PEDOT:PSS/EB-PANI are used as the sensing films for humidity and CO₂ detection, respectively. Different from traditional gas sensors, these organic sensing films can o...
This paper shows a correlation between surface effective porosity due to various sintering regimes and humidity sensitive electrical properties of the perovskite-based bulk type sensors, at room temperature. Furthermore, temperature transduction mechanism thick film sensors was studied in detail through electrochemical impedance spectroscopy (EIS) major transmissive components were detected by ...
Humidity is one of important environmental parameters, which refers to the water vapor content in the air. As one of the fundamental abiotic factors, humidity determines an environment where animals and plants can thrive, also influences the human life. There are three items commonly used to describe humidity, which are absolute humidity (AH), relative humidity (RH) and specific humidity (SH) [...
A hygrometer is an apparatus that measure humidity. Modern electronic devices use temperature of condensation or change in electrical capacitance to measure humidity difference. Humidity sensors are employed to provide an indication of moisture levels in the environment. To measure moisture level, various technologies are used. A capacitive type moisture sensor consisting of nanoporous thin fil...
Humidity indicators based on composite polyamide 66/cobalt chloride (PA66/CoCl2) nanofibrous membranes (NFMs) were successfully fabricated by electrospinning. A series of NFMs with various weight percentage of CoCl2 to PA66 were prepared, and their humidity sensitivity based on color changing and quartz crystal microbalance (QCM) were studied. Due to the color change property of cobalt chloride...
