Battery-powered devices could soon be a thing of the past thanks to a group of UK researchers who have created a novel energy harvester to power some of the latest wearable gadgets. http://phys.org/news258913319.html Technology Thu, 14 Jun 2012 19:00:01 EST news258913319 American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fuelled by hydrogen. http://phys.org/news251481651.html Technology Tue, 20 Mar 2012 20:00:04 EST news251481651 Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking uses in the electronics and composites industry. http://phys.org/news248437631.html Nanotechnology Tue, 14 Feb 2012 10:27:29 EST news248437631 (PhysOrg.com) -- Researchers have developed a tank-like robot that has the ability to scale smooth walls, opening up a series of applications ranging from inspecting pipes, buildings, aircraft and nuclear power plants to deployment in search and rescue operations. http://phys.org/news239289650.html Electronics Mon, 31 Oct 2011 20:00:01 EST news239289650 (PhysOrg.com) -- Traffic tunnels are often built in some of the most rugged and remote areas, which subjects them to extreme environmental forces while making them difficult to access. Ideally, the structural health of tunnels could be monitored in a way that requires minimal human maintenance while ensuring that the tunnels are consistently safe to drive through. http://phys.org/news232000903.html Technology Mon, 08 Aug 2011 05:42:14 EST news232000903 (PhysOrg.com) -- When it comes to finding the single best tool for building, digging, grasping, drawing, writing, and many other tasks, nothing beats the human hand. Human hands have evolved over millions of years into four fingers and a thumb that can precisely manipulate a wide variety of objects. In a recent study, researchers have attempted to recreate the human hand by building a biomimetic robotic hand that they have optimized to achieve near-human appearance and performance. http://phys.org/news217248602.html Technology Fri, 18 Feb 2011 10:50:27 EST news217248602 (PhysOrg.com) -- Now that scientists have developed a diverse assortment of nano- and micro-sized devices and materials, one of the biggest challenges is finding a practical way to incorporate them into macroscale systems. For example, tiny sensors, actuators, and electronic devices can only live up to their full potential when they can be exploited in large systems in everyday life. In a new study, researchers have developed an effective way to bridge the micro and macro scales by designing a network of microwires and micronodes that can be expanded from a few square centimeters to one square meter at low strain levels in the material. http://phys.org/news190534822.html Nanotechnology Thu, 15 Apr 2010 08:00:01 EST news190534822
