Mass sensitivity evaluation of a Love wave sensor using the 3D Finite Element Method

ZnO nanorod‐based Love wave delay line for high mass sensitivity: a finite element analysis

“…The phase mass sensitivity S ϕ is calculated from the slope of the graph between net phase shift and incremental mass loading. The phase mass sensitivity is related to the frequency mass sensitivity S f as per the relation [53] where k = 2π/λ is the wavenumber.…”

FEM Modeling Strategies: Application to Mechanical and Dielectric Sensitivities of Love Wave Devices in Liquid Medium

“…Ippolito's model used both the frequency and the time domain simulation with only a pair of fingers per IDT and the results obtained were quite different from the actual measurement. An FEM approach was also employed by Rocha-Gaso et al [6] for the evaluation of the sensitivity of a Love Wave device to mass effect. More recently, Achour et al [17] chose the FEM approach in a frequency domain simulation for the design of an SH-SAW device and also proposed a 2D model reducing calculation needs in resources.…”

“…However, the general FEM strategy applied to electroacoustic sensors, as presented in the literature, often uses even more simplified models, such as reducing the size of the transducers or of the device, achieving either similar or less accurate results compared to common methods. For example, Kovacs et al [5] calculated the optimum sensitivity of a Love Wave (LW) sensor with an analytical model in 1992, while Rocha-Gaso et al [6] were the first to reproduce this application using FEM in 2010, with an extremely simplified model and a time-consuming method.…”

Love Wave Biosensors: A Review

“…Thus, further efforts are required in order to achieve simulations able to reproduce real cases, which do not consume excessive computational resources. Nevertheless, some authors have simulated scaled LW sensors using this method [62][63][64][65].…”
