💡Could wireless charging highways for autonomous electric vehicles be the future? 🚗 Stanford scientists have developed a system that wirelessly delivers electricity to moving objects without compromising transfer efficiency. Their system worked on a small scale with an LED bulb, and they look to significantly increase the scale of electricity transfer so that it can be used for roads to support electric cars, body implants and other devices.

🔹What's New?

Scientists at Stanford University have developed a system that wirelessly delivers electricity to moving objects. It paves way for electric vehicles to be charged without stopping on the road and personal devices like medical implants and cell phones that are moving without compromising transfer efficiency. It could also lower costs and untether robotics in manufacturing.

Wireless technology is feasible through magnetic resonance coupling. Tuning coils to the same magnetic resonance frequency and correct angle positioning improves transfer efficiency. When an object moves, however, the flow of electricity can only be maintained if some aspects of the circuits, including frequency, are manually and continuously tuned- a complex process.

The team overcomes this challenge by eliminating the radio-frequency source in the transmitter, replacing it with a commercially available voltage amplifier and feedback resistor. This new system would automatically figure out the right frequency for varied distances without the need for active tuning or human interference.
They test this approach with an LED bulb and showed that its brightness remained constant as the receiver moved away from the source by up to about 3ft.
