Researchers at the University of Chicago levitated particles using sound to study how clusters are formed. They found that at a minimum six particles are needed to change between different shapes. By changing the ultrasound frequency, they could make the particle clusters move about and rearrange. This opens new possibilities for manipulating objects to form complex structures, develop new products and tools in the fields of wearable technology and soft robotics…read more.
