'I Dream a Dream'........Nah, I ain't gonna bust out any Susan Boyle songs for this post.... But I do dream. We all do. Especially us 'tech geeks' at Techmanity. Often I dream of a world where battery technology isn't an issue. Where we would have instant super fast charging that would charge our smart devices in seconds. A world where we can charge our phones without plugging it in....... 'HOLD UP!!!.......don't we already have that...I think you'll find it's Wireless charging?'Source: phandroid
hmmmmmmmm......Nope! I'm thinking of something much sweeter than that!
TRUE WIRELESS CHARGING.
Nowadays, when we think or talk about wireless charging, we often mention about this flat surface that you place your phone on that will then charge it.
That's all well and dandy. However, I still do not like the idea of having a cable connected and having to place my phone down in a certain spot and position. So for that sake, I do not believe that this is true wireless charging as it still requires a cable and little bit of user hostility. Thank you, uBeam
Finally, a company demo's true wireless charging. And soon, it will be available to us.
uBeam, uses a transmitter that emits high frequency sound rather than audible sound. However, this would be inaudible to you and your pets, uBeam say's. This is done through ultrasonic sound. The frequencies are so high that we cannot hear it. This is becuase, us humans only being capable of hearing sonic frequencies between 20kz and 20hkz and so uBeam goes above that.
The frequency then emits a target to other recievers that actively requests power.
When that receiver gains those ultrasonic frequencies. uBeam says it's, "Like a microphone, the receiver picks up the sound and converts it into usable electrical energy using our proprietary energy-harvesting technology."
Ultrasound has been studied to be safe for nearly 100 years.
Customers using the technology will be able to stand directly in front of the beam while being completely safe.
This is what wireless charging should be.
I dream of a future that we can walk into a local cafe (Starbucks...) and our devices will automatically charge themselves. Do you know how cool that would be?!?! No more cables. No more having to find a cable, replace one, untangle one, plug and unplug. Just simply. Plug in device once.......and charge forever!
