The effect of SU-8 patterned surfaces on the response of the quartz crystal microbalance [PDF]

open access: yes, 2005
In this work we present data showing the effect of patterning layers of SU-8 photoresist on a quartz crystal microbalance (QCM) and subsequent chemical treatment to increase their hydrophobicity. Patterns with 5 mu m diameter pillars spaced every 10 mu m

CMOS-Integrated Film Bulk Acoustic Resonators for Label-Free Biosensing

open access: yesSensors, 2010
The throughput is an important parameter for label-free biosensors. Acoustic resonators like the quartz crystal microbalance have a low throughput because the number of sensors which can be used at the same time is limited. Here we present an array of 64

Virtual Quartz Crystal Microbalance: Bioinspired Resonant Frequency Tracking

open access: yesBiomimetics, 2022
The reference acoustic properties of the quartz crystal used as a resonator are ensured by its high-quality factor (Q-factor). The microbalance of the quartz crystal (QCM) exploits the bulk acoustic properties of the quartz crystal.
