Paul Mitcheson Discusses Electric Vehicle Charging at New Scientist Live 2016
Professor Paul Mitcheson joined Red Dwarf actor and technology presenter Robert Llewellyn in a panel discussion at New Scientist Live 2016 (22-25 September 2016) , a major four-day festival of science, technology and engineering at the ExCeL exhibition centre in London. The discussion centered around electric vehicles, during which questions such as how do electric vehicles work, how will we charge them and what will they cost were raised. The event was attended by 450 festival visitors and featured demonstrations of the principal technologies involved.

Circuit and System Solutions for Simultaneous Wireless Powering, Tracking and Sensing at Ultra-low Power
Wireless power transfer (WPT) is foreseen as a key enabling technology for energy-autonomous wireless sensors, Internet-of-Things and Device-to-Device communication. RF energy, either scavenged from the ambient or intentionally provided to a wireless device, can be successfully exploited for autonomously sustaining its operations. In this lecture, the end-to-end circuit level co-design of a WPT link was described as the procedure to effectively address the system optimum efficiency. Specific selection of antenna elements and active sub-circuits were analyzed, depending on the power levels involved and on the specific application environment. The base-band design of the power management, unit used to dynamically provide the receiver with optimum loading conditions, was also analyzed. Finally, representative results for both communication and energy harvesting activities, combining UWB and UHF technologies for next generation RFID-enabled sensor systems, were discussed.

Wireless Power Transfer and Harvesting
Wireless power transfer is known from the charging of an electric toothbrush and maybe from the wireless charging devices for smartphones, tablets, etc. Charging distances for these devices are limited to a few millimeters. Power transfer is also possible over larger distances, but with less power. Notwithstanding this it is feasible to realize autonomous, wireless sensors without using batteries. Power is being ‘radiated’ by a central transmitting station. In this presentation the specifics of such systems were discussed. This was done through going through the history of radio, the history of wireless power transfer and the current state of the art. The presentation concluded with future perspectives for radiative Wireless Power Transfer.
