Fig. 1: Design and characteristics of a µ-QCM.
From: Microfluidic QCM enables ultrahigh Q-factor: a new paradigm for in-liquid gravimetric sensing
a Schematic showing the microfluidic channel system (with ~100 channels) placed over the working area (dashed circle) of a QCM sensor. Liquid is driven into the channels from left to right through capillary action. The SEM micrograph shows the cross-section of an individual channel. Normalized frequency and dissipation shift of the conventional and µ-QCM plotted as a function of mode number for b experiments and c FEA simulations
