Flexible and wearable acoustic wave technologies

Flexible and wearable acoustic wave technology has recently attracted tremendous attention due to their wide-range applications in electronics, sensing, acoustofluidics, lab-on-a-chip, attributed its advantages such as low power consumption, small size, easy fabrication, passive/wireless capabilities. Great effort been made development, characterization of rationally designed structures for next-generation based flexible electronics. Herein, advances fundamental principles, design, devices are reviewed. Challenges material selections (including both substrate piezoelectric film) structural designs high-performance discussed. Recent fabrication strategies, mode theory, working mechanisms, bending behavior, performance/evaluation Key sensors well lab-on-a-chip systems, Finally, major challenges future perspectives this field highlighted.
