Quartz Crystal Microbalance Sensor for Simultaneously Measuring Electrical Characteristics and Mass Changes

QCM Sensor Technology for Simultaneous Measurement of Electrical Characteristics and Mass

This technology relates to a quartz crystal microbalance (QCM)-based sensor capable of simultaneously measuring electrical characteristics and mass changes in real time.

Conventional sensors have required separate devices to measure resistance changes and mass changes, reducing analysis accuracy and operational efficiency. This technology forms electrodes on a single quartz crystal structure so that the two properties can be measured simultaneously.

As a result, it can simultaneously acquire multiple types of information in gas sensing or surface-reaction analysis, thereby improving both sensing accuracy and analytical efficiency.

Key Features:

• It simultaneously measures mass changes and electrical property changes in a single quartz-crystal-based device.
• It enables real-time multi-parameter measurement through an electrode-structure design.
• It is advantageous for improving the accuracy of gas sensing and surface-reaction monitoring.
