Liquid metal pump a breakthrough for micro-fluidics
RMIT University researchers in Melbourne, Australia, have developed the world’s first liquid metal enabled pump, a revolutionary new micro-scale device with no mechanical parts.

The unique design will enable micro-fluidics and lab-on-a-chip technology to finally realise their potential, with applications ranging from biomedicine to biofuels.

The research has been published this week in Proceedings of the National Academy of Sciences (PNAS).

Lead investigator Dr Khashayar Khoshmanesh, a Research Fellow in the Centre for Advanced Electronics and Sensors at RMIT, said currently there was no easy way to drive liquid around a fluidic chip in micro-fabricated systems.

“Lab-on-a-chip systems hold great promise for applications such as biosensing and blood analysis but they currently rely on cumbersome, large-scale external pumps, which significantly limit design possibilities,” he said.

“Our unique pump enabled by a single droplet of liquid metal can be easily integrated into a micro device, has no mechanical parts and is both energy efficient and easy to produce or replace.
