Introduction to QCM Sensors

Quartz Crystal Microbalance (QCM) sensors are highly sensitive devices that measure mass changes at nanogram levels, making them invaluable in various scientific and industrial applications. The technology relies on the piezoelectric effect of quartz crystals to detect minuscule variations in mass. As the mass on the crystal's surface changes, the oscillation frequency of the crystal shifts, allowing for precise monitoring of changes in mass and composition within a sample. This remarkable capability positions QCM sensors as essential tools in fields like material science, biological detection, and environmental monitoring.

Types of QCM Sensors

QCM sensors come in several types, each designed to cater to specific applications. Understanding these variations can aid in selecting the most suitable sensor for your needs.
