A microchip who abuses thesolar energy gave the possibility to have a digital control integrated in microrobot with a width slightly greater than that of a human hair. The study, published in the journal Science Robotics and conducted a number of researchers from the Cornell Universitycoordinated by Michael Reynoldsfaced a major challenge to develop autonomous robots with dimensions of less than 250 micrometers.
These microbots may be applicable in medicine, science environment and other industries but have a problem related to theirs autonomy. Thanks to the new solar chips, the system has a integrated control in microscopic robotsguiding the walking movements for three different types of microrobots by using pre-programmed electrical signals.
The shape memory actuators machines, ranging from robots to medical implants, to maintain their shape without being driven continuously, a fundamental feature for situations where they are unattached and a limited power. The actuators developed by the researchers have the potential to build adaptive structures on a micro scale.
We have developed a technique to combine the ‘brain’ of silicon electronics and the ‘legs’ of microactuators to build robots that are smaller than the naked eye can see. We are excited about medical and environmental remediation applications for microrobots with embedded electronics, such as the selective detection and degradation of pollutants or transporting cells throughout the body or performing microscale operations.
