Imagine being able to use commonplace objects like sea salt and a piece of cloth to capture moisture in the air to generate electricity or even power everyday gadgets with a non-toxic battery that is as thin as paper.
A novel moisture-driven electricity generation (MEG) device has been created by a team of scientists from the College of Design and Engineering (CDE) at the National University of Singapore (NUS). It is made of a thin fabric layer that is about 0.3 mm thick, sea salt, carbon ink, and a unique water-absorbing gel.
