This project concerns the modelling and experimental validation of new and improved acoustic radiation force devices. The main challenge is to understand what the optimal device would look like. By optimal we mean a device that is able to create an arbitrary force field. Furthermore it should do this as efficiently as possible, which could mean minimising the number of transducers and/or system complexity. These devices could be for mid-air ultrasonic haptics or microscale particle manipulation.

该项目涉及新的和改进的声辐射力装置的建模和实验验证。主要的挑战是了解最佳设备会是什么样子。所谓最佳，我们指的是能够产生任意力场的设备。此外，它应该尽可能高效地完成这项工作，这可能意味着将传感器的数量和/或系统复杂性降至最低。这些设备可以用于空中超声波触觉或微尺度粒子操纵。
