Be all set to witness an army of microscopic robots patrolling a human body! With technology progressing by leaps and bounds, invisible to the naked eye, these microbots are so small that a 10 cm silicon wafer can be installed with a million of these robots. They are small enough to be injected into the body and eventually they could be designed to hunt down and destroy cancer cells.
The legs of these little ‘creatures’ are inspired by Origami- the Japanese art of Paper folding. Somewhat mimicking the way our knees bend when we swim or walk! It has been stated that it would take less than a week to produce a million robots of this kind.
How do they work?
Every small bot consists of a simple circuit made up of silicon photovoltaics (which convert light into electricity and essentially functions as the torso and brain) and four electrochemical ‘actuators’; components that work as legs. The researchers control these bots by flashing laser pulses at different photovoltaics, each of which charges a separate set of legs. By flashing the laser back and forth between the front and back photovoltaics, the robot walks.
These robots are expected to serve as micro surgery devices. A swarm of such bots could be injected to locate bacteria or a tumour cell and then gradually destroy it.
