Graphene Sensor Boosts Camera Performance
I’m starting to think graphene may very well be the greatest thing ever to emerge from a laboratory. The latest in a long line of advancements: researchers at Nanyang Technological University have developed a graphene image sensor that can detect broad spectrum light and allow cameras to take clear photos even in low light.
Turn Your iPhone Into a Biomed Lab
Bored with your iPhone? Try turning it into a low-cost spectrophotometer. Some researchers at the University of Illinois at Urbana-Champaign have come up with a an iPhone app and a cradle packed with biosensor technology that will let users detect toxins, proteins, bacteria, viruses and other biological material.
The sensors could allow people to run field tests to spot poisons, measure food safety, and even make medical diagnoses using an iPhone.
NASA Explores Greenland Ice Sheet With Student-Designed Rover
An 800-pound, solar-powered rover designed by students at a Goddard engineering boot camp will be rolling across Greenland, collecting data on its depleting surface ice.
NASA has deployed the robot (the Greenland Rover and Goddard Remotely Operated Vehicle for Exploration and Research, or GROVER) to learn more about the causes and conditions of Greenland’s ice melt. The 6-ft.-tall rover carries ground-penetrating radar that can monitor snow accumulation in a more cost-effective way than satellite or plane-borne systems. It began a test run earlier this month.
Touch-Sensitive Electronic ‘Skin’
Robots with feelings have been a trope in science fiction since … well, since robots first appeared in fiction. But how about robots that can actually “feel”—as in physically experiencing the sensation of touch the same way humans do? Continue reading
Floating Robots Boost Solar Power
Unmanned drones aren’t just being used in the air. Liquid Robotics has announced the latest version of its floating sensor robots (Wave Glider SV3), which includes a hybrid propulsion system. The upgraded model uses solar power for propulsion; previously, the robots used solar cells to power onboard sensors and communications systems, while wave energy alone provided propulsion.
