WHAT IS WIRELESS POWER CHARGING?
The word “wireless” is often associated with wifi – but in this case, it’s simply not the same. Wireless power is simply the transfer of energy without the use of connecting cords or cables. In other words, wireless power enables charging smart devices without the need to plug them in.
In reference to this blog about charging, wireless charging accomplishes the same goal through a different method. Broken down into simpler terms, wireless charging is created by the transferring of an electrical current.
A few common examples of wireless charging include pads on desk surfaces for charging phones, phone cases that charge, and electric toothbrush stands. In order to use wireless power properly, one’s device must be compatible. As you can see from the aforementioned examples, wireless charging can take different forms and is utilized differently in various spaces.
According to Power By Proxi, “by eliminating the use of physical connectors and cables, wireless charging provides a number of efficiency, cost and safety advantages over the traditional charging cable.” This form of charging is safer by eliminating trip hazards and potential fire hazards of using frayed cables. It is also cost-effective in the long run by accommodating more people with fewer products and only requiring one purchase (see examples).
Inductive Coupling
Inductive coupling might be the most commonly considered and used form of wireless power. This technology has been around a bit longer than other popular forms of wireless charging. In fact, it’s probably how you charge your electric toothbrush. A coil in the charging stand actually creates a magnetic field which ultimately charges the brush.
Resonant Wireless Charging
Resonant charging is slightly less common. Resonant coupling was discovered by studies conducted at MIT when searching for a better solution than inductive coupling. Unsettled that inductive coupling had to be in very near proximity in order to charge, the studies set out to find a form of wireless charging that didn’t require proximity.
The studies at MIT summarized that inductive coupling encourages efficiency whereas resonant coupling is all about convenience. Both have different applications, and you can discover more about them in this article. Both are entirely safe to be used in buildings (including schools and hospitals) as a means of providing power and charging without the cords and cables usually envisioned when planning the design of buildings requiring power.
HOW DOES WIRELESS CHARGING CHANGE POWER IN THE WORKPLACE?
Imagine an office setting that is no longer tethered to a 6ft cable. Now imagine a workplace scenario where smartphones can be left sitting out on pads and in troughs to charge. The future is here – and keeping up with this technology as it advances will be critical in not only improving the way people interact with your designs but also with how people interact with their devices and (by proxy) their passions.
With such a demand for charging in order to stay connected, workspace design has been confined to specific layouts. And while technology and design have both evolved into beautiful, efficient, and creative solutions, limiting the need for cords even a small amount opens up the possibilities that much more. Wireless power has set designers free – so start speccing with this incredible technology today.
