The ability to swim upwards – towards the sun and food supplies – is vital for many aquatic microorganisms. Exactly how they are able to differentiate between above and below in often murky waters is still not understood ...
(Phys.org) —Shape memory polymers are "smart" plastic materials that can be transformed into a temporary shape and then return to their original shape, triggered by an external stimulus such as heat or pressure. These polymers ...
Meet MagnetoSperm! No, it's not a precursor to a movie called 'X-Men: The Next Generation' it's a tiny, swimming robot inspired by sperm cells.
A team of researchers at the University of Twente (Netherlands) and German University in Cairo (Egypt) has developed sperm-inspired microrobots, which can be controlled by oscillating weak magnetic fields.
(Phys.org) —Researchers have been taking tips from nature to build the next generation of flying robots.
Imagine robots no bigger than your finger tip scrambling through the rubble of a disaster site to search for victims or to assess damage. That's the vision of engineer Sarah Bergbreiter and her research team at the University ...
"Intelligent" materials that can respond to external stimuli are high on the wish lists of many scientists because of their possible usefulness in various applications from sensors to microrobotics. Canadian researchers are ...
Scientists have shown how controlled sperm cells inside tubes can be driven to target destinations using magnetic control. The significance of their investigation lies partly in what may be in store for in vitro fertilization. ...
(Phys.org) —Eukaryotic flagella, whip-like organelles that elegantly propel microorganisms and pump fluid, seem to embody simplicity on the microscopic scale. But appearances can be deceptive: Flagella are composed of 650 ...
(Phys.org) —One of the main components of a factory is the robots that transport and assemble objects of varying shapes and sizes. When scaling down to the micro level, the steel and wiring that these robots are made of must ...
