A Quantum Principle Could Change Wireless Charging Technology Forever – Futurism

In Brief Scientists have found a way to introduce a quantum principle into wireless charging systems. This innovation could expedite charging time and functionality while doing away with the previous limitations of wireless charging tech. A Better Range

While wireless chargingis an improvement over amess of entangled wires, the technology does not solve the issue of mobility your phone still needs to remain in one place to charge. This could change with the development of a new type ofcharging.

Current wireless charging devices operate using an electromagnetic field. For the power transfer between the charger and the device to remain optimal, the distance between the two must remain fixed. However, ateam out of Stanford has created a charger that cantransfer power to moving devices up to a meter away. Their research has been published in Nature.

The system uses a quantum mechanical principle called parity-time symmetry. Essentially, this means their charger can automatically adjust its power flow depending on the situation. The researchers demonstrated their device using an LED bulb. When the bulb moved further away, the distance was mitigated by the charger. This allowed the bulb to retain its brightness despite the motion.

Though this study only demonstrates the technology at a minor level, if scalable, it could essentially enable us to charge devices at the optimum rate despite a varying distance. This has exciting applications in a number of fields beyond just allowing you to comfortably use your phone while charging it.

Theoretically, it could revolutionize our ability towirelessly charge electric vehiclesas charging devices could be built into roads to charge the EVsas they drive past.The study also cites the potential to charge medical implants more efficiently. These devices are all implantedat slightly different depths, which can make charging them using existing technology complicated. This new technology would give patients the ability to move around while charging, as well.

While the teams technology is still in its nascent stages and has only charged a single moving LED so far, the concept has the potential to radically change how we power our lives in the future. Now, its just a matter of scaling it up.
