Title:
NOVEL LIGHT-ASSISTED QUARTZ CRYSTAL MICROBALANCE AND MEASUREMENT METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/109368
Kind Code:
A1
Abstract:
A novel light-assisted quartz crystal microbalance (2) and a measurement method thereof. The microbalance comprises a QCM/QCM-D chip (20), an oscillation circuit, a frequency counter (22), a computer (4), a reaction chamber (14), and a light source (6). Light emitted from the light source (6) is able to irradiate a surface of the QCM/QCM-D chip (20). By additionally configuring a light source with the ability to irradiate a chip surface, when irradiated the surface of the QCM/QCM-D chip (20) changes properties thereof, and irradiation of the surface of the QCM/QCM-D chip (20) greatly increases the resonance frequency. Correspondingly, irradiation of the surface of the chip (20) also changes mechanical properties and piezoelectric characteristics of quartz crystal, thereby effectively improving measurement sensitivity of a quartz crystal microbalance apparatus system.
