Surface Acoustic Wave (SAW) Tags Structures and Models

Elektronika ir Elektrotechnika, 2005
Surface acoustic wave (SAW) tags have a perspective future. For better read range and technology improvement is reasonable to use single destination converters, working on the main frequency harmonics. In the paper provided single destination double section SAW tag model, which assessed charge distribution in electrodes type, secondary effects, loss ...

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Design and Testing of a Minimal Configuration Underwater Micro‐Glider: Automating Lake and Reservoir Monitoring

Journal of Field Robotics, EarlyView.
ABSTRACT Uncrewed underwater vehicles (UUVs) have transformed oceanographic research through autonomous data gathering. Similarly, lake and other aquatic research can potentially be automated and transformed. However, UUVs would need to be smaller, lighter, less complex, and cheaper than currently available to make them more practical and user‐friendly
