Educational project
Ultrasonic levitator
SUPSI Image Focus
An ultrasonic levitator based on a phased array controlled by an FPGA was developed, capable of suspending and manipulating small objects. The transducer phases, computed using open-source software, are processed by the firmware. The prototype successfully levitated and stably controlled a small polystyrene sphere.
The project involved the design and realization of an ultrasonic levitator capable of suspending and manipulating small objects in real time through the acoustic pressure generated by sound waves.
The system is built around a phased array of ultrasonic transducers, driven by an FPGA and configurable via a UART interface using open-source software running on a PC.
Preliminary simulations were carried out to optimize the transducer arrangement and overall system performance, followed by PCB design, assembly, commissioning, and firmware development.
The final prototype was successfully validated, demonstrating stable levitation of a polystyrene sphere and its controlled movement within the acoustic field.
