This work presents an experimental testbed for a wireless power transfer (WPT) and backscatter-based tracking system for future implantable devices utilizing ultrasound via off-the-shelf components. Results showed a one-way 0.34mm localization resolution and tracking of an object in two dimensions with 6.32mm accuracy on the x-axis and 4.27mm on the y-axis. Ultrasonic WPT was modeled using a linear rectangular array approximation via an open-source MATLAB Toolbox k-Wave. The model was experimentally validated at distances from 11mm to 310mm using a linear rectangular array approximation of commercially available transducers for transfer efficiencies through air of up to 81.9 percent.
