Ultrasonic transducers are devices that can convert ultrasonic waves to electrical signals and vice versa. We're going to use this property to design a wireless power system that can power equipment that operates remotely.
This idea has been implemented in many forms, and the paper, Ultrasound Sensor-Based Wireless Power Transfer for Low-Power Medical Devices, is what I used as a starting point. The researchers test the efficacy of power transfer between an ultrasonic transmitter driven by a function generator and a receiver that has its signal rectified and amplified to power an Arduino.
This repository consists of the series of experiments I'm conducting, each building on the last.
