Engineers at the University of Washington have created a new communication system that takes advantage of wireless signals to power electronic devices without relying on batteries or wires. Known as ambient backscatter, the technique enables battery-less devices to exchange information with each other by repurposing existing Wi-Fi, mobile and television signals to act as both … [Read more...]
Researchers Design Acoustic-Based Data Transfer System for Smartphones
Researchers at Microsoft Research India have developed a new alternative acoustic-based data transfer system with capabilities similar to Near Field Communication (NFC) that requires no specialized wireless hardware. Derived from radio-frequency identification (RFID) technology, NFC enables low data rate, bidirectional communication between devices in close proximity in a … [Read more...]
TVS Array Protects Computing Applications from ESD and EFT
Semiconductor company ProTek Devices has released a new low capacitance transient voltage suppressor (TVS) array designed to protect computing applications from the damaging effects of electrostatic discharge (ESD) and electrical fast transients (EFT). “At higher operating frequencies or faster edge rates, insertion loss and signal integrity are a major circuit protection … [Read more...]
Microwave Absorption Film Suppresses Noise Greater than 30 dB Over 4GHz
A new thin microwave absorption film capable of suppressing noise from high frequency electronic devices has been released by Nikkan Industries Co., Ltd, a manufacturer of flexible laminates for flexible electronics. Featuring suppression rates of 20 dB at 2 GHz, 30 dB at 4 GHz and stable for frequencies greater than 4 GHz, the 42.5 microns thick Nikram film reduces both … [Read more...]
Stretchy Conductive Material Could Lead to Better Brain Implants
Researchers at the University of Michigan have created a stretchy conductive material that could one day find use in medical implants and flexible display screens and batteries. Created from gold nanoparticles and polyurethane, the material retains its conductivity even when stretched to several times its original length. Using an electron microscope to examine the effects of … [Read more...]
Signal-Filtering Algorithms Tackle Smartphone Interference
New signal-filtering algorithms developed to reduce interference in smartphones could provide users with faster performance, longer battery life and fewer dropped calls. Created through a partnership between Kansas State University’s Electronics Design Laboratory and Lawrence, Kan.-based research company Avatekh Inc., the algorithms are intended to more efficiently combat … [Read more...]
Scientists Use Electromagnetic Radiation to Identify Counterfeit Goods
British scientists have devised a way to use electromagnetic radiation to identify counterfeit textiles, a discovery that could help recover billions of dollars in lost revenue for the fashion industry each year. World-famous and highly competitive, the British fashion industry is worth £21 billion ($32.5 billion) to the UK economy, and as much as £37 billion when wider … [Read more...]
FCC Announces Rule Change for 60 GHz Band
The Federal Communications Commission (FCC) has announced a rule change regarding the high frequency 57-64 GHz band in a decision that could bring faster, more cost-effective broadband services to both rural and urban areas. FCC acting chairman Mignon Clyburn and commissioners Jessica Rosenworcel and Ajit Pai unanimously approved changes to the commission’s Part 15 rules last … [Read more...]
U.S. Navy Tests Military Spectrum Sharing Potential
The U.S. Navy has taken a large step towards opening military frequencies for greater commercial use with a recent experiment that evaluated whether or not military and commercial devices can successfully share the same frequency without interference. In a recent test off the coast of Virginia's eastern shore, the Navy activated an AN/SPY1—a powerful naval radar system that … [Read more...]
High-Speed EMI Test Receiver Unveiled
The new ESR26 high-speed EMI test receiver for standard-compliant EMC testing up to 26.5 GHz has been unveiled by Rohde & Schwarz at the IEEE International Symposium on EMC in Denver, Colo. The new R&S ESR26 EMI test receiver covers the 10 Hz to 26.5 GHz frequency range and performs conducted or radiated certification measurements in line with commercial standards such … [Read more...]
