Rolling microswarms along acoustic virtual walls

HIGHLIGHTS

• who: Zhiyuan Zhang from the (UNIVERSITY) have published the article: Rolling microswarms along acoustic virtual walls, in the Journal: (JOURNAL) of 30/03/2022
• what: In the absence of real boundaries, the authors show that microswarms can execute rolling along virtual walls in liquids, impelled by a combination of magnetic and acoustic fields. The authors report a strategy for manipulating chain-shaped microswarms into rolling without reliance on physical boundaries. The authors compare the rolling velocities of the microswarms to those obtained in other microroller demonstrations. The approach provides a viable alternative to conventional propulsion . . .
