DOI: 10.1109/ted.2024.3409509

Abstract: We have developed a technique of on-chip multisite acoustofluidic manipulation using aluminum nitride on silicon (AlN-on-Si) piezoelectric micromachined ultrasonic transducers (PMUTs). We demonstrate nine-channel acoustically driven particle enrichment on a $3\times 3$ PMUT array fabricated… read more here.
