Germaphobes take note: LG has just invented a high-tech handrail sterilizer

LG may be best known for its computers, TVs, and smartphones, but South Korea’s fourth-largest business conglomerate has its fingers in plenty of other pies as well. The latest LG development? A gadget that the company is claiming is the world’s first “Handrail UV LED Sterilizer,” designed to remove germs from the handrails of escalators.

Yes, that’s a long way from Android mobile phones, but it’s no less reliant on some pretty cool tech. LG’s handrail sterilizer skips out on boring solutions, such as hand wipes, to take on the problem of germ-ridden handrails. Instead, it uses ultraviolet LED technology to shoot out UV rays from a fixed position. As the moving conveyor belt passes the device’s target zone, the UV LED Sterilizer kills 99.99 percent of the germs, which accumulate from the thousands of people who have put their hands onto said moving petri dish every single day.

However, despite being capable of obliterating germs, the technology is utterly harmless to the human body since it doesn’t rely on any chemicals or heavy metals.

This isn’t the first time we’ve written about the disease-killing prowess of ultraviolet light. In the past, we’ve published articles about gadgets like UVe, a Roomba-style cleaning bot which uses low-wavelength ultraviolet light to clean surfaces, and even medical research that uses UV for eliminating cancer cells.

While the technology may not be entirely new, however, LG’s solution is definitely pretty darn neat. For one thing, the sterilizer is around the size of half an A4 sheet of paper, and can be easily installed without having to make any major changes to an existing facility. And in a suave touch, it also doesn’t need to be plugged into mains power since the wireless device itself is powered via energy from the movement of the handrail.

Right now, there’s no announcement concerning how much the Handrail UV LED Sterilizer will cost, but LG notes that the device has already gained the necessary CE certification required by the European Union, and the KC certificate required in South Korea.

Hopefully it won’t be too much longer before it arrives in the United States, and we can rest easy in airports and shopping malls. Or, at least, our hands can.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
