More Power To Wearable Technology

Wearable tech is indeed everywhere. It is taking on multiple forms and it is also performing multiple roles. Fitness, health, navigation, information, social networking – almost everywhere you go you can find some wearable tech device or the other. But, you know one thing that gives sceptics of wearable tech legitimate fuel? Well, it is the technology that will power these wearable devices.

And this is indeed a genuine concern because in almost every observation about wearable technology, you are likely to find some mention about the batteries that power wearable devices. The way I see it, there are a few concerns associated with the batteries that are powering wearable technology.

These concerns can be broadly categorized into:

  • Size
  • Charging time
  • Safety and
  • Output.

battery life


Very few wearable devices will do well with bulky batteries. This is especially true when you’re talking about wearable devices which are extremely small by themselves. For instance, wearable devices which come in the form of jewelry, ear pieces or even devices which can be implanted in one’s body – none of them can afford to have bulky batteries!

Wearable technology is likely to be high on power consumption. After all, devices are capable of monitoring your body and its vital signs through the day. Or maybe you rely on your device to help you find your way while you are travelling or even in seeking more information on the world around you. That means a lot of processing power, ergo a lot of power consumption.

Batteries also need to be completely safe. They cannot combust, overheat or damage the wearable device in any manner. Batteries also need to be comfortable with all the physical challenges that the wearable device itself faces. For instance, a fitness bracelet will see a lot of physical activity of different kinds! The battery should be able to take all the different kinds of stresses as well.


Wearable tech batteries should also be capable of being charged in a decent amount of time. And that decent amount of charging time should result in enough power to keep the wearable device going for, well, a decent amount of time.

It is indeed great to see the kind of technology that is coming into play when one talks about batteries for wearable technology itself. Just a few days ago, Panasonic announced their pin-shaped lithium ion battery. Ambient power sources can be game changers in wearable battery life. As Tom Emrich of Wearable App Review says, “energy harvesting… will be a major value proposition for why we wear our devices.”

Graphene is another popular material of choice in this domain. If Samsung is talking about it in the wearables space then researchers in MIT are talking about it in the supercapacitor space! Another company that is worth watching is Imprint Energy. This company has created flexible batteries that can even be printed in a 3D printer.

Sure, a lot of work being done in the charging platform is still work in progress. but when the perfect solution is found, then its inventor surely will be the most powerful person in this world! Simply because Wearable Technology is likely to be everywhere on Earth isn’t it?
