A team of researchers from Carnegie Mellon University have developed a 3D printed, three-fingered robotic hand with fiber optical sensors that are stretchable. The hand is able to detect forces that are less than a tenth of a newton. “Using fiber optics, the team of researchers placed 14 strain sensors into each of the robot’s fingers, which are closely modeled on the skeletal … [Read more...]

High School Students and UPenn Professor Build Radio Telescope in West Philadelphia
This past summer, as part of UPenn’s Summer Science Academy Program, 12 high school students along with James Aguirre, associate professor in the School of Arts & Sciences’ Department of Physics and Astronomy, turned an out-of-service TV satellite dish on the roof of the Enterprise Center in West Philadelphia into a 30-foot radio telescope. The telescope has been given the … [Read more...]
First U.S. Public School District Limits Wi-Fi Radiation Exposure
Ashland, Massachusetts Public Schools have announced they will be reducing Wi-Fi radiation exposure to students and teachers via Wi-Fi Device “Best Practices.” “Spurred by parent Cecelia Doucette's concerns about the lack of safety data on Wi-Fi and children, the district investigated the issue and developed a policy to substantially reduce wireless exposures to students and … [Read more...]
Ground-penetrating Radar Uses Electromagnetic Radiation to Reveal ‘Super-Henge’
With the help of ground-penetrating radar, researchers have discovered that there are 90 large stones, known as Durrington Walls, hidden underground in a village near the famous Stonehenge monument in England. Archaeologist Vince Gaffney and his team announced this discovery at the British Science Festival in Bradford, England earlier this month. “Durrington Walls is about … [Read more...]
Canadian Police to Receive New Radio System after EMI Issues
Sault Ste. Marie Police are preparing for a new radio system, since their current system, which is 15 years old, experiences communication problems and constant radio frequency interference. However, police dispatchers still have problems ahead. “Motorola is phasing out support the console's main components. The withdrawal of assistance starts in 2016 and ends in 2018,” … [Read more...]
Invisibility Cloak to Improve Military Operations
A team of scientists from the University of California, San Diego (UCSD) have developed a material that resembles an invisibility cloak. The material could change the face of military operations and would allow weapons and maybe even military personnel to function while undetected. UCSD scientists have tested the “first effective dielectric metasurface material—an ultra-thin, … [Read more...]
‘Radiogate’ Controversy in First NFL Game – Pittsburgh Experienced EMI in Helmets
Last night, during the NFL season opener in New England between the New England Patriots and the Pittsburgh Steelers, a technology malfunction reportedly caused the Patriot’s radio broadcast to air on the headsets of the Steelers’ coaches during the entire first half of the game. The nickname ‘Radiogate’ has surfaced – a play on the Patriot’s previous ‘Deflategate’ controversy … [Read more...]
RFID Sensors Allow for the Collection of Football Data
The NFL has joined with Zebra Technologies to launch MotionWorks RFID sensors, which will be placed in the shoulder pads of all the players. “The sensors will each emit unique radio frequencies that will be captured by the 20 receivers that have been put in all the stadiums that are used by the NFL,” according to the Tech Times. Through these sensors, data about the players … [Read more...]
Magnetic Field Cloak to Assist MRI Scanners and Medical Industry
Scientists from the Autonomous University of Barcelona have created a magnetic field cloak, or ‘wormhole,’ which could lead to better MRI scanning. “The wormhole allows a magnetic field to be transported across space but it is not the kind of cosmic tunnel popularised by science fiction. Rather, the magnetic field at one end of the wormhole appears at the other end as an … [Read more...]
New 1kW X-band Model added to line of SSPAs
Diamond Microwave has introduced the 1kW ultra-compact pulsed GaN X-band SSPA, which is a 1kW X-band model to the company’s range of GaN-based pulsed solid-state power amplifiers (SSPA). The model is an ultra-compact SSPA operating over a 1200MHz bandwidth centred at 9.5GHz. The design measures 244 x 134 x 50mm3 excluding heatsink and connectors. It’s an alternative to a … [Read more...]
