Indeed, novel metamaterial structures can develop the efficiency of mechanical and physical features of ultrasound energy receivers (US-ETs), including ultrasound-driven piezoelectric and triboelectric nanogenerators (US-PENGs and US-TENGs) for advantageous applications. This review article first summarizes the fundamentals, classification, and design engineering of UMMs after introducing ultrasound energy for WET technology. In addition to addressing using UMMs, the topical progress of innovative UMMs in US-ETs is conceptually presented. Moreover, the advanced approaches of metamaterials are reported in the categorized applications of US-PENGs and US-TENGs. Finally, some current perspectives and encounters of UMMs in US-ETs are offered. With this objective in mind, this review explores the potential revolution of reliable integrated energy transfer systems through the transformation of metamaterials into ultrasound-driven active mediums for generators. With the quick growth of ultrasound energy transfer technology based on triboelectric and piezoelectric nanogenerators (TENGs and PENGs), the recent progress in achieving efficient energy harvesting is presented, with a review of design strategies through understanding the influence and significance of ultrasonic metamaterials concept in ultrasound-driven TENG and PENG devices for current applications. image English Wiley-VCH Verlag Advanced Ultrasound Energy Transfer Technologies using Metamaterial Structures Article 10.1002/advs.202401494 1 Advanced Science, v.11, no.31 Advanced Science 11 31 Y scie scopus 2-s2.0-85196184118 Chemistry, Multidisciplinary Nanoscience & Nanotechnology Materials Science, Multidisciplinary Chemistry Science & Technology - Other Topics Materials Science Review; Early Access POWER TRANSFER MEDICAL DEVICES ACOUSTIC METAMATERIALS HARVESTER DESIGN SYSTEM DRIVEN WAVE NANOGENERATORS OPTIMIZATION metamaterials nanogenerators piezoelectric triboelectric ultrasound wireless energy transfers
