Abstract
We report a near-field communication (NFC)-enabled quartz crystal microbalance (QCM)-tag instrumentation suitable for wireless mass loading sensing applications. The proposed instrumentation utilizes a low-power microcontroller-based Pierce oscillator frequency counter system to measure series resonance frequency $(f_{0})$ of the QCM over a time period. The system was able to record the change in $f_{0}\,(\Delta f)$ caused by mass loading to the NFC's electrically erasable programmable read-only memory. The $f_{0}$ measured using the proposed system was then validated against impedance analyzer measurement, and the maximum error was measured to be 0.0004%. An Android application was then developed to read log $f_{0}$ using a smartphone. Further, we demonstrated wireless measurement of the mass loading rate of a dc sputtering system, a well-known vacuum deposition technique adopted in semiconductor process industries. Accordingly, the proposed system is an inexpensive plug-and-play solution for real-time wireless in-situ measurement of mass loading changes in sealed chambers or hazardous environments where manual measurement or wired measurement is difficult.
