Tiny medical helper
Only the use of gallium makes a medical mini-robot possible. Just half a millimeter in size, without a motor, and capable of removing deposits in human arteries – this is the profile of a recently developed crab-shaped mini-robot.
It is able to move thanks to a so-called “memory foam” made of a nickel-manganese-gallium alloy. At 0.25 millimeters per second, the tiny device even manages a quite respectable sprint while performing its tasks. It was the technology metal gallium used here that made the mini-robot’s functionality possible. Demand for gallium is rising rapidly, not only in medical applications but also, for example, in solar energy and the production of “green” hydrogen. The resulting price jump in recent weeks and the expected further price increases now present a good opportunity for additional purchases or a new investment.
