This technology has the potential to provide meaningful charging to batteries of smartwatches and smartglasses.
Among the latest breakthroughs in wearable technology has been one that has involved the use of WiFi in order to send electricity into mobile devices and wearables such as smartwatches, fitness bands, and even smartglasses.
The scientists were able to experiment with WiFi antennas to the point that they were able to power up small devices.
They used ambient signals to power the wearable technology. In order to keep a steadier flow, they combined the ambient signal with noise. This rather basic modulation concept has worked quite promisingly and has opened up a new world of possibilities when it comes to being able to charge various types of mobile and wearable devices. They have been able to power up several types of device using this PoWiFi and have been able to charge a fitness tracker from a distance as far as 23 feet by combining the antenna with a rechargeable battery.
This suggests that WiFi will be able to send data as well as power to wearable technology, which is highly promising.
From this point, it will be interesting to watch the development of this technology as it is worked into various kinds of mobile devices over time. This also appears to be only a jumping off point for the types of uses that a WiFi antenna could have. In this case, a special type of temperature sensor was also able to be powered up through the use of a normal WiFi signal simply by using certain specific techniques and changing the signal in order to meet to needs for transmitting.
Technology Quotes That Invite Thought -
As we start to depend increasingly on our mobile devices and as batteries are decreasingly able to keep up with the demand on the batteries that power those devices, it is interesting to see this particular addition to tech, which could help to allow batteries to be charged easily regardless of where a device user happens to be.
As long as there is a router around to which to connect, then electricity for recharging could be grabbed and wearable technology, smartphones, tablets, and other gadgets could stop continually running out of juice just when they are most needed.
