Wood, ice and the disks in a human spine are all viscoelastic materials. Viscoelasticity is a quality involving both viscous and elastic properties at the same time. QCM-D is a surface sensitive technology that can characterize the viscoelastic properties of thin films.
Surface science affects and contributes to areas: IT, materials and interface science, biomaterials, biotechnology, medicine, nanotechnology and cleantech.
The QCM with an added D measures an additional parameter, the dissipation factor. The QCM-D provides more information about the system under study than traditional QCM.
How does QCM-D work? Perhaps you know that a QCM-D sensor is made out of quartz, which is a piezoelectric material. But what does that really mean?
