Unlike eaten pills or injected liquids, which have a time delay, the tiny robot could withhold a dose of medicine and then administer it as soon as it reaches its target. Scientists have now developed gelatinous robots to crawl through human body to deliver medicines.
Scientists have created small gelatinous robots capable of crawling through the human body to administer medication or diagnose ailments.
According to Jill Rosen of John Hopkins University, the "gelbot" is driven by nothing more than temperature fluctuations, and its novel design, which mimics an inchworm, is among the most intriguing ideas in the field of soft robotics.
"It seems very simplistic, but this is an object moving without batteries, without wiring, without an external power supply of any kind—just on the swelling and shrinking of gel," said David Gracias, a senior project leader and professor in the Department of Chemical and Biomolecular Engineering at Johns Hopkins University.
