Energy-harvesting card treats 5G networks as wireless power grids

A team from Georgia Tech has just announced a world-first: a 3D-printed rectifying antenna the size of a playing card that can harvest electromagnetic energy from 5G signals and use it to power devices, turning 5G networks into wireless power grids.

Wireless communications put a lot of energy into the air, and over the years we’ve covered a number of efforts to harvest that energy. Short-range Wi-Fi signals have been the target of several projects, TV broadcasts and radio signals have been the focus of others. One device even hopes to increase the life of a smartphone’s battery by 30 percent just by harvesting some of the radio waves the phone itself is generating.

But 5G communications offer a whole new opportunity. 5G has been designed for blazing fast and low-latency communications, reads the Georgia Tech team’s latest study, published in the peer-reviewed journal Scientific Reports. To do so, mm-wave frequencies were adopted and allowed unprecedently high radiated power densities by the FCC. Unknowingly, the architects of 5G have, thereby, created a wireless power grid capable of powering devices at ranges far exceeding the capabilities of any existing technologies.

Breakthrough in electronic display fabrics could help pave the way for smart clothing

The fabric is about as bright as the average flat-screen TV. The researchers noted their prototype was also significantly more durable than conventional thin-film flexible displays, making it more suitable for practical use. The performance for most of the display remained stable after 1000 cycles of bending, stretching and pressing, and 100 cycles of washing and drying.

Floating Holographic Buttons May Make Smart Toilets Even Better

“The Murakami Corporation has partnered with Parity Innovations, a startup that developed a holographic display technology, the Parity Mirror, which breaks up a projected image using a series of tiny mirrors and then refocuses them into a reconstituted image that appears to float in mid-air. What the Murakami Corporation brings to the table is its infrared sensors, which are able to detect the presence of fingers without them having to make physical contact. The result is a series of glowing buttons that don’t actually exist but can still be activated by touching them.”


Japanese smart toilets already provide a luxe experience, but this high-tech upgrade will take them to the next level.

Nano Dimension set to lead 3D printed electronics market with AME technology

Since its proprietary technology launched back in 2014, industrial 3D printer OEM Nano Dimension has built a name for itself in the world of additively manufactured electronics (AME).

With ongoing refinements to its flagship DragonFly LDM® 3D printer, the company is now doubling down on its 3D printing of high-performance electronic devices (Hi-PEDs™), an area in which it’s seen significant success in recent years. The Hi-PEDs™ targeted by the company often cannot be produced using traditional printed circuit board (PCB) manufacturing processes.

Yoav Stern, CEO of Nano Dimension, states, “We’re the 3D printing company for customers who need to stay on the cutting edge of electronics design. You’re creating the latest innovations in hardware development and electronic circuits. You need an additive manufacturing solution that allows you to go where no one has gone before in electronics design — and to get there faster and easier than ever before.”
