Trembling aspen leaves could save future Mars rovers

Researchers at the University of Warwick have been inspired by the unique movement of trembling aspen leaves, to devise an energy harvesting mechanism that could power weather sensors in hostile environments and could even ...

Paper-based lateral flow device to detect uranium in groundwater

The presence of uranium in groundwater can lead to severe health problems, from renal failure to cancer. Standard methods to detect uranium involve time-consuming processes and expensive, non-portable equipment. Measurements ...

Integrated sensor could monitor brain aneurysm treatment

Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms—bulges in blood vessels—but the procedure requires frequent monitoring while the vessels heal. Now, a multi-university ...

Intelligent flow sensor for demand-controlled ventilation

VTT Technical Research Centre of Finland and Fläkt Woods Oy have developed a flow sensor that enables ventilation to adapt to actual demand, thereby improving indoor air quality and energy efficiency. The flow control utilises ...

Robo-whiskers mimic animals exploring their surroundings

Many mammals, including seals and rats, rely on their whiskers to sense their way through dark environments. Inspired by these animals, scientists working at the University of Illinois at Urbana-Champaign and Illinois' Advanced ...

Bio-inspired eye stabilizes robot's flight

Biorobotics researchers at the Institut des Sciences du Mouvement - Etienne-Jules Marey (CNRS/Aix-Marseille Université) have developed the first aerial robot able to fly over uneven terrain that is stabilized visually without ...

Borrowing from whales to engineer a new fluid sensor

How can a humpback whale and a device that works on the same principle as the clicker that starts your gas grill help an unmanned aerial vehicle (UAV) fly longer and with more stability?
