Bio-Inspired Ultra-Compact Acoustic Transmitter - Bubbles as a Means of Weak-Source Amplification

申请人已正式获得EPSRC未来超声工程博士培训中心(FUSE)的全额资助，FUSE是格拉斯哥大学医学和工业超声中心(CMIU)和斯特拉斯克莱德大学超声工程中心(CUE)的合作伙伴关系。一个博士项目已经被接受。项目总结如下。与其产生的波长相比，对尺寸较小的水声设备的需求越来越大。目前在较低频率下进行高功率传输的方法依赖于使用大位移或大辐射面积，这对于真正紧凑的设备是不可行的。超声波工程中心的Strathclyde电子和电气工程系已经与泰利斯海事任务系统一起研究了较小的水船雄性昆虫(Micronecta Studtzi)，这种昆虫通过有效地产生水下声音进行通信，尽管它的输出波长比它的输出波长小得多。这是通过动物使用它的供气作为辅助放大器来实现的。该项目旨在复制这种现象。

The applicant has a formal offer for a fully-funded studentship in the EPSRC Centre for Doctoral Training in Future Ultrasonic Engineering (FUSE) is a partnership between the Centre for Medical and Industrial Ultrasonics (CMIU), University of Glasgow and the Centre for Ultrasonic Engineering (CUE), University of Strathclyde. A PhD project has been accepted. The project summary is as follows. There is a growing need for underwater acoustic devices that are small in size compared to the wavelength that they produce. Current methods for high-power transmissions at lower frequencies rely on the use of large displacements or a large radiating area which is not feasible for a truly compact device.Work has already been done at the Strathclyde Department of Electronic and Electrical Engineering in the Centre for Ultrasonic Engineering in conjunction with Thales Maritime Mission Systems studying the lesser water-boatman male insect (Micronecta scholtzi ) which communicates through efficient generation of underwater sound despite being much smaller than the wavelength of its output. This is achieved by the animal using its air-supply as a secondary amplifier. The project is to replicate this phenomena.
