From June 2017 to March 2018, I was a research assistant in Professor Arbabian's lab.
Ultrasound Phased Array for Wirelessly Powering Implanatable Devices
My first project was building an phased array ultrasound controller. This project involved circuit design, FPGA programming, embedded C (on a Xilinx Zynq SoC), and a python interface for computer control. The system was designed for focusing ultrasonic power on millimeter-sized implantable devices. A system description and measurement results are available in the paper below.
