Stretchy enough to be worn as a ring, bracelet or any other accessory that touches the skin, this new low-cost wearable device transforms the human body into a biological battery.
Has been developed by researchers at the University of Colorado at Boulder, and can generate about 1 volt of energy for every square centimeter of skin space.
Polyimine: an elastic material
The secret of its elasticity and ease of repair is in its base material: an elastic material called polyimine. If it breaks, for example, you can put the broken ends together and they will seal again in just a few minutes.
This also allows it to be completely recyclable, making it a cleaner alternative to traditional electronic devices: in a special solution that will separate the electronic components and dissolve the polyimine base; Each and every one of those ingredients can be reused.
Although the voltage it provides is very low, it could be enough to power electronic devices such as watches or activity bracelets.
It also takes advantage of a person's natural heat, using thermoelectric generators. to convert internal body temperature into electricity.
