AlN is a piezoelectric material used in telecommunication applications due to its high surface acoustic wave (SAW) velocity, stability, and mechanical strength. Its performance is linked to film quality, and one method to achieve high-quality films g

The competition between various carbohydrates in the binding to Concanavalin A (Con A) can be exploited in gravimetric microsensors that detect changes in mass or viscoelasticity as a function of glucose concentration. Such sensors are based on the i

The mass and viscoelastic properties associated with the binding of the Concanavalin A (Con A) – dextran ( ${M}_{w} = 80$ kDa) affinity assay as a function of glucose concentration, was investigated using a quartz crystal microbalance (QCM). The Co

This paper presents a new approach for the design of film bulk acoustic resonators (FBARs) with high-quality factor ${Q}_{a}$ at antiresonant frequency ${f}_{a}$ . Lamb waves are among the main contributors to the loss of energy at ${f}_{a}$ and the

This paper investigates and compares three methods for the analysis of the thin film bulk acoustic resonator (FBAR) in order to study the propagation of plate waves in the device. The finite element method (FEM) is compared to the Transfer Matrix (TM
