The ultra-small machine lifts objects 165 times the mass

US scientists have successfully built a nanoscale machine capable of lifting 165 times its weight.

Scientists at Rutgers University in the United States have successfully built a machine that weighs 1.6 milligrams, but can lift objects 165 times its mass, according to UPI. The results are published in the journal Nature on August 30.

A machine that mimics the functioning of a muscle, by converting chemical energy into mechanical energy. Its power comes from the process of loading and removing ions between ultra-thin molybdenum disulfide (MoS 2 ) sheets, only three micrometers thick.

MoS 2 is an inorganic mineral with a molecular structure similar to graphene. While the atoms of the same layer are tightly bound together, the bonds between the layers are weak, allowing them to be easily separated.

"We found that the device could lift a much heavier load than itself by impacting the MoS 2 plates with a small voltage," said Manish Chhowalla, a professor of materials science at Rutgers University. , to speak.

Chhowalla says future MoS 2 plates will be used to make high-pressure, high-voltage electrolytic actuators. "The next step is to scale up and try to make gearboxes that can move larger objects , " Chhowalla said.
