Scientists Looking to Unlock Quantum Mechanics Tech to Offer Advanced Wireless Charging

June 16, 2017, By Sanjeev Ramachandran

Wireless charging is gearing up to become the new normal. Even the upcoming iPhone 8 is expected to ship out with the new standard of charging on board. Despite making the gadgets untied from wires, wireless charging hasn’t gone to the extent to which it can provide mobility.

That’s because it still requires your devices to be kept over charging pads to get it juiced up. The freedom of movement is quite denied in that instance, which is what researchers are now trying to scotch down. A team at Stanford University also now appears to have come up with a solution for this, and it’s the quantum mechanics which they believe would be the cracker.

The current range of wireless charging devices makes use of inductive charging measures which uses electromagnetic field to transmit energy. However, researchers at Stamford have instead switched to technology called parity-time symmetry that creates a self-adjusting power flow to charge external devices even with a distance of one meter in between them.

The quantum mechanics technology involves an amplifier that controls the transmission of power from a transmitter to the receiver. This controls the guided output of power, which automatically adjusts when the device is taken further away from the base station. This will guarantee an uninterrupted flow of current, though constrained to a threshold distance.

The technology is still a long way off before it becomes feasible to the current domain of devices. The tests were initially carried out using LED light bulbs, and it’s being taken forward so as to get it feasible on smartphones and similar devices. The developers also say that the technology could be amplified to work over greater distances.

Though being tested on smartphones, the team is looking forward to develop the technology initially for powering up solar panels above the Earth’s atmosphere to help achieve better efficiency with solar power generation.
