Scientists have created the world’s smallest electric generator at just one atom thick

A team of scientists at the Georgia Institute of Technology have developed the world’s smallest electric generator. At just one atom thick, the device is made from molybdenum disulphide (MoS2), which is a clear, flexible material that opens up huge possibilities for the future of electricity generation.

The new electrical generator is an example of piezoelectricity, or electricity that’s generated from pressure. Piezoelectric materials have had almost an infinite amount of potential uses, especially in the nanotechnology field, but until now, scientists have struggled to make them flexible and thin enough to be practical.

In order to test whether or not MoS2 would be piezoelectric on the atomic scale, the team behind the technology flaked off thin layers of the MoS2 onto a flexible substrate with electrical contact. Read More
