Detection of alcohol concentration level in sanitizer using PMMA/PVA coated glass substrate
PRZEGLAD ELEKTROTECHNICZNY(2023)
摘要
A proposed sensor detecting alcohol concentrations level in sanitizer is fabricated by employing Polymethyl Methacrylate (PMMA) and Polyvinyl alcohol (PVA) coated glass substrate as a sensing platform. The platform is integrated with Arduino Nano as a data acquisation in order to realise the biosensor. The sensor module was aligned with a green light-emitting diode and photodetector via 3D printing based setup. Light leakage through the glass substrate affects forward and backward scattering when exposed to variation of alcohol content in sanitizer. The proposed biosensor is capable to detect alcohol in sanitizers with 60%-80% concentrations. It produced exceptional sensing performances results in term of sensitivity, linearity and stability. In terms of sensitivity and linearity, PMMA-coated glass substrate outperforms PVA by 6% and 2% improvement respectively. Henceworth, the proposed sensor features low production costs, ease of use, and stability which show a good potential as alcohol sensor.
