Abstract :
In this contribution, we present novel multiplexed frequency spectrum analyzer instrumentation to extract operational parameters and completely characterize the frequency response of an array of quartz crystal microbalance sensors. The effectiveness of the proposed instrumentation is proven by experimental measurements over a range of frequencies.
