| Summary: | An acetone liquid sensor has been successfully demonstrated by utilizing glass substrate coated with
Hydroxyethylcellulose/Polyvinylidene Fluoride (HEC/PVDF). The sensing mechanism is based on the change in refractive
index (RI) of the HEC/PVDF coating layer when exposed to acetone concentration variations. When the light progress
through the sensing material, the intensity decrease due to absorption and scattering. The proposed sensor's produces
exceptional results where output voltage has decreased linearly from 1.8 V to 1.3 V. It showed a good response with
sensitivity of 0.0331 V/% and a linearity of 99.1 % as compared to an uncoated glass substrate. |
