Wireless Power for Autonomous Sensor Systems
Main challenges for tomorrow's WPT technologies
Description of the magnetodynamic WPT technology.
The characteristics of low-frequency WPT makes the magnetodynamic WPT technology relevant for some specific applications. The through-metal and subsea WPT capabilities make it interesting for industrial, scientific and military interests. The fact that the technology is safe around human makes it attractive for biomedical applications and for the wearable market. Besides, the magnetodynamic WPT is also interesting for mid-range charging of distributed systems using high-Q resonant receivers.
Envisioned applications of through-metal and subsea WPT are for charging autonomous systems (pipe inspection robots, autonomous underwater vehicles (AUV), rescue robots…) or for charging isolated/confined systems (sensor systems in industrial process tanks, silos…).
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
