Abstract:
The Internet of Underwater Things (IoUT) will enable naval military, scientific, and commercial applications. Since these systems use traditional batteries, powering them in deep water remains a challenge.
This project describes the first batteryless underwater sensor node that can be wirelessly recharged by ultrasonic waves from longer distances than current technologies. First, the architecture of an underwater platform that extracts electrical energy from ultrasonic waves is presented.
This system is then interfaced with an underwater digital communication unit. We design a supercapacitor-based prototype storage unit. Experiments show that harvested energy can power the sensor node’s sensing operation and ultrasonic communications modem.
The article evaluates system power transfer efficiency. We demonstrate that our approach can cover longer distances with less transmission power than alternatives due to ultrasonic wave attenuation in water. Finally, we measure system efficiency experimentally.
