Innovative New Wireless Antenna is Dramatically Smaller
Researchers at Northeastern University have demonstrated a new type of radio antenna that operates in the frequencies used for some cellular networks and Wi-Fi, but is up to 100 times smaller than current antenna designs. The new antenna can be manufactured on a single chip approximately 1mm across. It receives radio signals by first converting radio waves to acoustic waves, then to electrical signals, and the same in reverse for transmitting. The existing method of converting directly between radio and electrical signals requires an antenna with a physical length 1/10 the radio wavelength. The new technique uses the properties of acoustic waves to permit an antenna made of a piezomagnetic membrane that's just 1/1000 the physical length of the radio wavelength. The piezomagnetic material is joined with a piezoelectric material to create the necessary electrical link. The technology could shrink the size of phones and wearables. It may also open up lower frequencies — which today require antennas too large to carry around — to mobile devices.
WattUp Distance Wireless Charging Coming To Major-Brand Phone
Apr 7, 2016
Energous has revealed that a "tier 1" consumer electronics company has agreed to implement WattUp wireless charging technology in a number of consumer products, including a phone. WattUp is an RF-based wireless charging technology that can be implemented in a number of ways, including transmitters that can send power wirelessly up to 15 feet, using a large array of antennas and beam-forming technology to send focused energy in the 5.8 GHz radio band.
Samsung Forges Bio-Processor for Wearables
Dec 29, 2015
Samsung is taking direct aim at the wearable market with a new processor custom-designed to monitor health and fitness data. The Bio-Processor combines Analog Front Ends (AFEs), a micro controller, a power management integrated circuit, a digital signal processor, and an eFlash memory chip into a single module.
FCC Fines T-Mobile $60,000 for Failing to Secure Antennas
Nov 12, 2015
The FCC today proposed a fine of $60,000 against T-Mobile, which it says failed to adequately warn and prevent the public from stepping too close to cellular antennas. Specifically, T-Mobile didn't properly block off nor place signs near three antennas (2 AWS, 1 PCS) on a building in Phoenix, Ariz.
Researchers Devise Fire-Resistant Battery
Jan 18, 2017
Adding a flame-retardant to select elements of lithium ion batteries many prevent fires, according to researchers at Stanford University. The researchers figured out how to create a nonwoven electrospun separator out of triphenyl phosphate and coated it with a heat-activated polymer.
Researchers Create Low-Power, High-Resolution Display Tech
Nov 24, 2015
Scientists at the University of Oxford have discovered new display technology that can be used to make bright, high-resolution screens while hardly drawing any power. Oxford is bullish enough on the technology that it formed a new company, called Bodle Technologies, to commercialize the discovery.
