PCB and circuit design for piezoelectric-NEMS characterization

Nanoelectromechanical resonators (NEMS) are being developed from more than two decades from now. The fabrication techniques as well as metrology ones are constantly improving, allowing a possible democratization of their uses in the consumer and industrial market in few decades. Their application fields for sensing are wide : from the detection of mass, temperature, radiation, spins to their use for bio-sensing analysis, for example. NEMS are also facing their own set of challenges : they are highly sensitive to any internal and external noises. This report is a condensed overview of a semester project done at the Advanced NEMS group (EPFL) on the signal characterization improvement of a suspended microchannel resonators with integrated piezoelectric transduction, developed in-house.
