Uncorded Tech: The Present and Future of Wireless Charging


While companies are making close range charging more convenient than it was, we can look forward to chargers, even in the near future, that make keeping our devices operational a breeze. Nowadays wireless charging is becoming more common and more in demand.

Nikola Tesla was experimenting with wireless charging well over a century ago—long before anyone was looking for it. But with the variety of battery-powered devices that we have today, wireless charging is becoming more common and more in demand. Although it's been in use among consumers for several years now, there is still room for growth.

Close Range Charging

Current devices rely on inductive technology to acquire a charge. It's easy and flexible for engineers to design appealing products around. Companies like TYLT have come up with chargers that let you freely position a device anywhere on the pad, and even tilt it an angle or place it in a stand so you can continue using it as it charges. This is a very convenient approach for today's users.

Mid-Range Charging

This method uses resonance between magnetic coils to charge at a greater distance. Placing a multiple resonance charger on a desk will let you charge a device without restrictions on physical use. While this is a technology without industry standards or much of a choice in products, companies are due to begin marketing these products in the near future.

Long Range Charging

A charging system can work at considerable distance, such as within a business or university lecture hall. There are several possible methods for directing the energy of infrared lasers, radio waves, ultrasound, and more. Researchers haven't quite worked out the details, such as signal loss over distance. Working long range chargers have been developed experimentally, but that's a long way from affordable consumer devices.

In the Future

Well before inductive chargers become ubiquitous, we're likely to see them replaced by the first generation of resonance chargers. It will probably be two or three years before mid-range chargers make an impact. Long range charging is even further off.

If one of these laboratory models becomes viable as a commercial product, there will still have to be safety testing, industry cooperation, and due to their nature, the approval of the FCC. But when the time comes that long range charging is perfected, and in a way that's scalable, we might see long range systems charging tools, appliances, and even vehicles—so charging personal devices is hardly even a concern.
