Applied acoustic devices using ultrasound radiation force

抄録

Objects can be levitated, transported, and deformed by the radiation force of ultrasound. In this paper, we introduce non-contact transportation techniques and optical lenses using acoustic radiation force. Small objects and liquid droplets can be transported without contact by controlling acoustic fields, which is expected to be applied to cell manipulation techniques. Additionally, optical lenses with a focal length that can be controlled by changing their shape via acoustic radiation force can help downsize camera modules.
