Quartz Crystal for Thin Film Thickness Measurement using Embedded Software (PSoC)
Abstract: Programmable System on Chip (PSoC) based embedded read-out design for Quartz crystal which measures thickness of a thin film during deposition has been describe in this paper. Excited quartz sensor to its resonance frequency of 5 MHz, kept nearby the substrate measures the deposited film thickness by monitoring change in quartz resonance frequency. The change in the quartz crystal resonance frequency due to deposition decreases linearly with thickness. The change …

The Future is Smelling: Exploring the Potential of e-Nose
Abstract: The human sense of smell, a complex and often underestimated faculty, allows us to perceive the world through volatile organic compounds (VOCs). This ability to detect and differentiate between aromas, flavors, and even potential hazards has inspired the development of the electronic nose, or e-nose. More than just a novelty, e-noses are rapidly becoming sophisticated analytical tools with applications that span across numerous industries. By mimicking the biological processes of …
