Non-contact transport system for particles based on acoustic levitation

Ultrasonic phased array is based on acoustic levitation technology for non-contact manipulation of particles and has a wide range of applications in the fields of biology, micro-assembly, and chemical engineering. However, most current ultrasonic phased arrays are limited by their structure, making it difficult to achieve non-contact transport of microparticles. Therefore, in order to achieve non-contact transport of microparticles, this study proposed an ultrasonic transport system. This system uses an ultrasonic phased array as the end effector and realizes the spatial transport of particles through a multi-degree-of-freedom robotic arm. The experimental results indicate that the ultrasonic transport system proposed in this study can achieve non-contact transport of microparticles. The ultrasonic transport system proposed in this study has a simple structure and small size and can be integrated as an independent non-contact operation module into experimental platforms in different fields, which is expected to promote the application of acoustic manipulation.
