Perovskite solar cells are one of the most exciting green energy technologies to emerge in recent years, combining low cost with high energy conversion rates. Now, researchers at the Swiss Federal Institute of Technology in Lausanne (EPFL) have found a way to cut their cost even further by developing a charge-carrying material that is much cheaper, highly efficient, and could even help address the technology's current major weakness by significantly lengthening the lifespan of the panels.
Building machines that replicate the delicate touch of a human hand is a complex undertaking that has seen the development of all kinds of soft robotic grippers, from squishy green blobs to boa constrictor-inspired claws. Scientists are now claiming an important advance in this area, demonstrating a robotic device that can better grasp fragile objects through the help of electroadhesion, the very same phenomenon that sees balloons cling to ceilings after being rubbed on your hair.
Portable test kits represent an advance in disease diagnosis, as their
ready availability increases chances of earlier detection and treatment.
This type of technology is constantly evolving, and sometimes
inspiration can come from surprising sources. Such is the case with
research carried out by a Swiss team, which has borrowed from the
mechanics behind the firefly's glow to develop a sensitive molecule
Three years ago, Swiss research institute EPFL announced its plans to build a spacecraft that could grab orbital debris and then carry it back towards Earth, burning up in the atmosphere with it on its way down. Called CleanSpace One,
the satellite was depicted at the time as using a claw-like grasping
tool. Now, however, EPFL has announced that it will utilize a folding
conical net to essentially gobble up bits of space garbage.
A telepresence robot developed at the École Polytechnique Fédérale de Lausanne (EPFL) that can be controlled by thought may give people with severe motor disabilities a greater level of independence. Successfully put through its paces by 19 people scattered around Central Europe – nine of whom are quadriplegic and all of whom were hooked up to a brain-machine interface – the robot handled obstacle detection and avoidance on its own while the person controlling it gave general navigation instructions.
Micro-drones may be versatile in the air, but carry one in your pocket or bag and you run the risk of damaging its propellers. While carry cases are available for a number of models, some are catering to the micro-drone class with arms that fold away for safe storage. Two Swiss roboticists are the latest to take this approach, with a palm-sized quadcopter that spreads its wings and springs to life in less than a second.
