چکیده

 Abstract
 Capacitive humidity sensor based on Polyvinyl-alcohol (PVA) electrospun nanofibers was fabricated. PVA were synthesized through versatile electrospinning technique. The heat treated and characterized via Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM) thermogravimetric Analyzer (TGA) for structural, morphological thermal properties. fibers of admirable structure selected deposited over interdigitated alumina electrodes the investigation Relative Humidity (RH) sensing characteristics. variation in capacitance with RH measured 48pf at 32-92% RH. dynamic response study confirmed durability stability sensor. material exhibited quick recovery time takes 13.27 seconds to measure maximum value. Thus, proposed has potential possible application devices.

متن کاملFabrication and Evaluation of a Graphene Oxide-Based Capacitive Humidity Sensor
In this study, a CMOS compatible capacitive humidity sensor structure was designed and fabricated on a 200 mm CMOS BEOL Line. A top Al interconnect layer was used as an electrode with a comb/serpent structure, and graphene oxide (GO) was used as sensing material. XRD analysis was done which shows that GO sensing material has a strong and sharp (002) peak at about 10.278°, whereas graphite has (...
متن کاملA High Temperature Capacitive Humidity Sensor Based on Mesoporous Silica
Capacitive sensors are the most commonly used devices for the detection of humidity because they are inexpensive and the detection mechanism is very specific for humidity. However, especially for industrial processes, there is a lack of dielectrics that are stable at high temperature (>200 °C) and under harsh conditions. We present a capacitive sensor based on mesoporous silica as the dielectri...
