NUS researchers invent ‘humidity digester’ to keep rooms feeling cool at zero energy cost

Asst Prof Tan Swee Ching and his team of researchers from the Dept of Materials Science and Engineering at NUS Faculty of Engineering have invented a novel way to lower the humidity in a room without using energy. They developed a hydrogel which, when combined with some chemicals and a thin carbon mesh, can absorb water vapour from the air and break it down to hydrogen and oxygen molecules, lowering the humidity in a room.
