Wearable devices are amazing pieces of tech but they have their own issue; this wearable device battery is looking to solve that issue. The battery will allow wearable devices to essentially last forever by using the user's body heat to power the battery, which in turn powers the device itself.
It's only a matter of time before smart watches become the norm. With that on the horizon, users will be looking for a sustainable source of energy to power the devices, and this is where the KAIST “wearable thermo-element" comes into play.
The strip battery is made of fiberglass, which can be easily embedded into clothing and other devices. The strip is only 10cm, so it can be concealed and it powers the devices perpetually. This strip will make buying wearable devices much more accessible.
