Mass-sensitive electro-acoustic devices such as surface acoustic wave (SAW)micro-balances, capable to operate with aqueous media are particularly favorable for thedevelopment of biosensors. Their dimensions and physical properties offer a large poten

In this study, we used surface acoustic wave (SAW) sensors based on a delay line configuration for measuring particulates matter (PM10 and PM2.5) mass concentration. These sensors exploit the gravimetric sensitivity of Love waves and operate at 125 M

The performance of single-port surface acoustic wave resonators based on 150 nm thick Z-axis oriented LiNbO 3 films on C-sapphire was studied by means of simulations. The resonance frequencies close to 3.7 GHz were targeted. The dependence of wave ve

The effect of LiNbO3 substrate polarization on a charge density at the interface with epitaxial ZnO and MgxZn1−x O films was studied in comparison with ZnO films on dielectric sapphire substrates. An excitonic emission and optical properties such a

Interface acoustic waves (IAWs) propagate along the boundary between two perfectly bonded solids. For a leakage- free IAW, all displacement fields must be evanescent along the normal to the boundary inside both solids, but leaky IAWs may also exist d

The possibility to manufacture single devices allowing the 10 GHz threshold to be largely overcome has been demonstrated using Electron-beam lithography. In this paper, we propose an original alternative to lithographic techniques based on the Focuse

Bulk acoustic waves excited in thin piezoelectric films have revealed their capabilities for addressing the problem of high frequency RF filters (above 1 GHz). In this paper, we propose an alternative to thin film deposition consisting in single crys

SAW devices are widely used for radio-frequency (RF) telecommunication filtering and the number of SAW filters, resonators or duplexers is still increasing in RF stage of cellular phones. Therefore, a strong effort is still dedicated to reduce as muc
