Ultrasound Research Group

The main research areas of the URG include:

• Ultrasonic particle manipulation. Ultrasonic particle manipulation is a non-contact manipulation method that uses ultrasonic waves to trap, orient and transport small objects. URG is developing a 3D printing/assembling technology based on ultrasonic particle manipulation.
• Ultrasonic electrostatic transducers. Ultrasonic electrostatic transducers have a wide bandwidth and are ideally suited for parametric sound systems or high-accuracy distance measurements. URG has developed novel electrostatic transducers and their manufacturing method based on a PCB manufacturing processes.
• Parametric sound. Parametric sound systems use ultrasonic waves modulated with audio signal to reproduce sound in localized regions. URG is developing algorithms for improving sound quality of parametric sound systems.

URG also develops specialized ultrasound hardware and electronics solutions for scientific and commercial uses. Currently two products are offered:

• Ultrasonic Array Controller UAC128 – a multi-channel continuous wave array controller developed by URG. It was designed to be primarily used in ultrasonic particle manipulation systems.
• Levitator Model D – a demonstration unit for ultrasonic levitation/manipulation of particles such as EPS and even water droplets.
