Tiny temperature sensor powered wirelessly with radio waves

One of the problems for the smart buildings of tomorrow is that they may depend on some very un-smart wires to power them. To cut the cord, Eindhoven University of Technology (TU/e) researcher Hao Gao, as part of his PhD thesis, is developing a tiny transmitting temperature sensor that is powered by radio waves to eliminate the need for wires or batteries. Instead, it picks up radio waves from a special router, converts them into electricity, and uses it to transmit readings.Read More

Amera visualizes wireless signals for home and cyber-security

Imagine being able to use the proliferation of wireless signals that exists today for something more than social media posts and entertainment. That's what Cognitive Systems is doing with its Amera device. It detects wireless signals from a variety of sources like cell towers, Wi-Fi base stations and rogue signals, and turns them into cyber security alerts, crowd insights, and wireless network monitoring.Read More

Wi-FM uses local radio stations to improve Internet speeds

Wi-Fi connections are great when they work quickly and efficiently, but when they suddenly slow down inexplicably it can be very frustrating. Surprisingly, this isn't usually caused by a slow connection from your ISP, rather it occurs when two physically close Wi-Fi connections interfere with each other. Now researchers from the McCormick School of Engineering at Northwestern University have come up with a simple way to prevent this – and improve Wi-Fi speeds – by using Frequency Modulation (FM) and a smart time-sharing system that maximizes data throughput.

V-Moda loses the cables with latest Crossfade Wireless headphones

Through much planning, research, engineering, and maybe a little bit of caving-in to consumer demand, V-Moda has unveiled what many had believed would never be. The V-Moda Crossfade Wireless over-ear headphones are the company’s first Bluetooth-enabled product after so many years of cable-only models. The Crossfade Wireless is designed to offer virtually-identical analog and wireless playback while maintaining V-Moda’s iconic silhouette.Read More

Ultra low-power wireless communication through the human body using magnetic fields

Be it on the inside or the outside, the human body is becoming host to an ever-increasing array of electronic devices that need to wirelessly communicate with each other. Now engineers working at the University of California, San Diego (UCSD) have come up with a different type of wireless communication that sends ultra low-power magnetic fields through the human body. This makes it extraordinarily more energy efficient and secure from prying eyes than comparable wireless communication technologies.Read More

Roll up, roll up: LG targets mobile accessory market with portable Rolly Keyboard

Touchscreens may be extremely versatile and a good fit for mobile devices, but one thing they don't lend themselves to well is extended typing sessions. As a result, we've seen numerous portable keyboards designed to easily fit in a pocket alongside your smartphone. Now LG is getting in on the act with its Rolly Keyboard, which it calls the industry's first solid rollable wireless portable keyboard.Read More

Magura unveils wireless dropper post at Eurobike

Dropper seat posts are becoming increasingly common on mountain bikes – among other things, they allow the rider to drop the saddle down out of the way when they’re adjusting their riding position on steep descents, but then pop it back up again afterwards. They do, however, require yet one more cable to strung along (or inside of) the frame. At this year’s Eurobike show in Germany, Magura has presented an alternative – the Vyron eLECT, which is the world’s first commercially-available wireless dropper seat post.Read More
