A flexible bracelet harvests electricity through body heat.
Now, a Swedish-based startup has developed flexible, customisable solar cells that convert indoor and outdoor light into electricity. Enabling e-book readers, headphones and keyboards to run without batteries.
The solar cells comprise a titanium dioxide layer coated with light-absorbing dye and the maximum intake under different lighting conditions is defined by the dye colour.
An innovative electrode material contained in the layers below leads to a one-thousand fold increase in conductivity compared with previous flexible cells.
The new cells are non-poisonous, contain neither rare earths nor conflict minerals and can be recycled.
Meanwhile, Switzerland is banking on solar followers, while Turkey is following a hemispherical design.
