Revamping a skill Deco Masterpiece

THE PICTURE AS A WHOLE features technology through the lens of photographers.

On a monthly basis, IEEE Spectrum selects probably the most stunning technology images recently captured by photographers all over the world. We choose images that reflect a significant advance, or perhaps a trend, or which are just mesmerizing to check out. We feature all images on our site, and something also appears on our monthly print edition.

Benefit from the latest images, and when you have suggestions, leave a comment below.

Power Station Restoration

This beautifully outfitted room may be the newly restored Control Room A at the Battersea Power Station in London. For half of a century, the energy hub controlled the flow of current that met one-fifth of Londons electricity demand. The hub was decommissioned in 1983. Now it’s been returned to its original 1930s Art Deco glory. The painstaking restoration, filled with period detailsincluding the gauges engineers relied on once the station was fully functional and a glass elevator that may give visitors a panoramic view of the London skylinetook decades to perform.

Augmented-Reality Contacts

In March 2022, IEEE Spectrum Senior Editor Tekla S. Perry took a glimpse at the planet through the most recent iteration of Mojo Visions AR lens. She didnt put the lens in her eye as the company hadn’t yet completed the prototypes safety testing. Still, she saw enough to verify that Mojo Visions engineers had pulled off several exciting advances. Included in this were a 14,000-pixel-per-inch monochrome microLED display, eye tracking utilizing an accelerometer, a gyroscope, and a magnetometer, and onboard power using medical-grade microbatteries. By June, the team was confident that it had hurdled any remaining safety concernsso much in order that Mojo Vision CEO Drew Perkins [shown here] put a couple of Mojos high-tech lenses to the test in their own eyes.

Hearing With Light

The cochlear implant can be an impressive feat of engineering. Determining how exactly to use pulses of electric energy to stimulate the cochlear nerve that feeds auditory information to the mind was a large achievement. But in accordance with users, the implants still leave a lot to be desired. Thats why several researchers from institutions across Europe have already been trying to supply the implants a complete new ring. Rather than manipulating electrons to stimulate the cochlear nerve, theyve invented a fresh version that does it with photons. The beams of light could be controlled with an even of specificity that helps solve cochlear implant wearers major complaints, including voices that sound flat and robotic, stripped of the subtle inflections that help communicate things such as sarcasm. The implant captures a few of the dynamics of music that were lost in transmission. Also it promises to resolve the cocktail-party problemwhere background noise, including other conversations, overwhelms the signal representing a speakers voice.

Weather-beating Battery

Even prior to the introduction of the overall Motors EV1 in 1996, it had been clear that when were ever likely to replace cars powered by fossil fuels with electric vehicles, well need batteries that take and deliver charge reliably in both hot and cold climates. For EV propulsion, weve come quite a distance because the lead-acid chemistry still used to power electric starters and cabin electronics. Now a team of researchers at the University of California, NORTH PARK, says it has hit upon a fresh electrolyte chemistry for lithium batteries that doesnt freeze at temperatures right down to 100 C. And as the dibutyl ether solvent in the brand new electrolyte binds weakly with the lithium ions in solution, those ions are absolve to move easily and develop a strong current, even on probably the most frigid of winter mornings. Whats more, the dibutyl ether resists evaporation and side reactions that could irreversibly decompose the electrolyte once the battery is subjected to high temperatures on hot summer days.
