Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically ...
In 1939, a Russian engineer proposed a "flying submarine"—a vehicle that can seamlessly transition from air to water and back again. While it may sound like something out of a James Bond film, engineers have been trying to ...
Nanoengineers at the University of California, San Diego used an innovative 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots—called microfish—that swim around efficiently in liquids, ...
The concept of walking on water might sound supernatural, but in fact it is a quite natural phenomenon. Many small living creatures leverage water's surface tension to maneuver themselves around. One of the most complex maneuvers, ...
Wearable electronic devices for health and fitness monitoring are a rapidly growing area of consumer electronics; one of their biggest limitations is the capacity of their tiny batteries to deliver enough power to transmit ...
Swarms of microscopic, magnetic, robotic beads could be scrubbing in next to the world's top vascular surgeons—all taking aim at blocked arteries. These microrobots, which look and move like corkscrew-shaped bacteria, are ...
Today the National Science Foundation (NSF) announced two five-year, center-scale awards totaling $8.75 million to advance the state-of-the-art in medical and cyber-physical systems (CPS).
Though the past 15 years have seen an exciting run of creative scientific advances in fabricating three-dimensional (3D) structures by self-folding of 2D sheets, the complexity of structures achieved to date falls far short ...
(Phys.org) —Robots have great value in a wide variety of areas, and while robots acting alone can be helpful in collecting data, ones that "talk" to each other can yield endless potential. That's especially true when the ...
Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute forces exerted ...
