Technology could make it possible to use radio emissions from cell phone networks to wirelessly power sensors and LEDs.

Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell phone networks or Bluetooth connections. This technology could potentially provide wireless power to sensors, LEDs and other simple devices with low energy requirements.

“By eliminating wired connections and batteries, these antennas could help reduce costs, improve reliability and make some electrical systems more efficient,” said research team leader Jiangfeng Zhou from the University of South Florida. “This would be useful for powering smart home sensors such as those used for temperature, lighting and motion or sensors used to monitor the structure of buildings or bridges, where replacing a battery might be difficult or impossible.”

Samsung said on Monday that hackers breached its internal company data, gaining access to some source codes of Galaxy-branded devices like smartphones.

The statement from the South Korean electronics giant comes after hacking group Lapsus$ claimed over the weekend via its Telegram channel that it has stolen 190 gigabytes of confidential Samsung source code.

Samsung did not name any specific hackers in its statement nor what precise data was stolen.

The looming shutdown of 3G networks won’t just impact older phones.

With AT&T’s 3G network shutting down next week, and other carriers following suit later this year, a range of products require updates to continue working, including some home alarm systems, medical devices such as fall detectors, and in-car crash notification and roadside assistance systems such as General Motors’ OnStar.

Just as many mobile carriers have urged customers to swap their older 3G iPhones, Android phones, e-readers and other handheld devices for newer models ahead of the shutdown, other businesses are urging customers to upgrade or replace some of the everyday products and services in their homes and cars before they drop connectivity.

If there is no doctor in the house, Amazon’s Alexa will soon be able to summon one.

Amazon and telemedicine provider Teladoc Health are starting a voice-activated virtual care program that lets customers get medical help without picking up their phones.

The service, for health issues that aren’t emergencies, will be available around the clock on Amazon’s Echo devices. Customers can tell the voice assistant Alexa that they want to talk to a doctor, and that will prompt a call back on the device from a Teladoc physician.

“Now that Ukrainian airspace is in dispute and being contested and Ukrainian airspace runs right up alongside NATO airspace, we have conveyed to the Russians that we believe a conduit at the operational level is needed … so we can avoid miscalculation,” a senior Pentagon official told POLITICO. “And we have not received any response from them in terms of whether they agree, whether they are willing to set something up.”

As the U.S. and NATO rush weapons into Ukraine, DoD officials want more military channels to Putin’s top leaders. But Russia’s not picking up the phone.

The late 90s and early 2000s were a breakout time for mobile phones, with cheap GSM handsets ushering in the era in which pretty much everybody had a phone. Back then, a popular way to customize one’s phone was to install a sticker that would flash when the phone rang. These required no batteries or any other connection to the phone, and [Big Clive] has dived in to explain how they worked.

It’s an old-fashioned teardown that requires a bit of cutting to get inside the sticker itself. A typical example had three LEDs in series for a total voltage drop of around 7V, hooked up to two diodes and a PCB trace antenna. A later evolution used raw unpackaged components bonded to the PCB. Future versions went down to a single diode, using the LEDs to serve as the second. The basic theory was that the PCB traces would pick up RF transmitted by the phone when a call was coming in, lighting the LEDs.

In the 2G era, the freuqencies used were on the order of 300 MHz to 1.9GHz. A combination of the change in frequencies used by modern phone technology and the lower transmit powers used by handsets means that the stickers don’t work properly with modern phones according to [Big Clive].
