Scientists have created an army of a million microrobots that can go through a medical needle

Computer chips morph into tiny robots with medical applications

Engineers describe the technology of creating a million robots less than 0.1 mm in size from a 10-centimeter silicon wafer.

The tiny machines are so small that they cannot be seen with the naked eye, but they have a new class of photosensitive drives, reminiscent of vestigial limbs, with which they can move. To control the movements of robots, scientists from Cornell University aimed a laser at different parts of a tiny chain on the back, which operate analogs of pairs of legs..

They can work in any environment, including conditions with extreme temperatures and acidity.

Micro robots can pass through the thinnest hypodermic needle, allowing them to be injected into the human body. Due to their dependence on an external energy source, current puppets are difficult to manipulate in tissues, so the researchers plan to significantly modernize them and program them to perform certain tasks, for example, attacking cancer cells..

However, according to the developers themselves, this can take years or even decades..

To enhance the functionality of tiny robots, scientists recently proposed a new design method that allows them to be reconfigured..
