This is the world’s smallest microelectronic robot
An international team of researchers led by Chemnitz University of Technology (Germany) has developed the world’s smallest microelectronic robot. We tell you what it looks like and what the characteristics of this tiny automaton are.
Microelectronics robots, micro robots or microbots are small mobile robots governed by a microcontroller and designed to carry out certain tasks. In the last decade, scientists have shown great interest in the development of this type of device, especially because of its potential applications in the medical field.
Although chemical propulsion micromotors are currently being tested to cure diseases in various medical studies, these are simple systems that have no electrical power or microelectronic units on board, so it is not possible to control their direction. Unlike these devices, the new micro robot does have electrical power and offers remote control.
The microbot designed by these scientists is made of a flexible material and measures 0.8 mm long x 0.8 mm wide x 0.14 mm high. To give you an idea of its approximate size, a penny has a diameter of about 16 mm.
This device is equipped with a complete microelectronic system, and has a microcontroller, actuators and full manoeuvrability. To obtain the electrical energy it needs to operate, it has a wireless induction power transmission system that delivers the electricity it needs on the spot.
It has a propulsion unit that allows it to move thanks to the pressurized expulsion of oxygen bubbles through two microtubes. The equipment controls this process thermally in one of the two microtubes, which allows the device to be directed in several directions, as you can see a little further up in the video.
Moreover, in case the task to be performed requires it, it is possible to control several microbots simultaneously in a swarm.
Among the potential applications of this micro robot are the targeted administration of drugs or the diagnosis of diseases from inside the body.
