Underwater Communication Using Acoustic Parametric Arrays [PDF]
The 4th International Electronic Conference on Sensors and Applications, 2017 This paper presents a study of different types of parametric signals with application to submarine acoustic telecommunications. In all of them, the carrier frequency is 200 kHz, which corresponds to that resonation of the transducer under study, while they differ by the different modulations they present. In this sense, we study modulations with sweeps

Optoacoustic Neuromodulator by In Situ Photothermal Curing of Polydimethylsiloxane
Advanced Optical Materials, Volume 14, Issue 16, 24 April 2026.Photoacoustics provides a powerful tool for generating miniaturized and patterned ultrasound field. Here, we report a novel, highly versatile method for fabricating optoacoustic emitters via an in situ photothermal curing process of PDMS. This technique enables high‐precision deposition across diverse platforms, including programmed flat substrates and
