Successful tests demonstrated the ability to penetrate through cardboard sheets.
Practical applications include scanning packages and monitoring patient hydration.
Future advancements aim to extend scanning range and ensure privacy.

Imagine having a smartphone that allows you to peer through solid objects, just like Superman’s X-ray vision.

Practical applications include scanning packages and monitoring patient hydration

This extraordinary capability, once confined to the realms of science fiction, is now inching closer to reality thanks to a pioneering project underway for over 15 years.

Dr. Brian Ginsburg, director of RF/mmW and high-speed research at Texas Instruments’ Kilby Labs, was quoted saying “It took 15 years of research that improved pixel performance by 100 million times, combined with digital signal processing techniques, to make this imaging demonstration possible. This disruptive technology shows the potential capability of true THz imaging.”

“We designed the chip without lenses or optics so that it could fit into a mobile device. The pixels, which create images by detecting signals reflected from a target object, have the shape of a 0.5-mm square, about the size of a grain of sand,” Dr. Wooyeol Choi, assistant professor at SNU, said.

Safe and Efficient Scanning

Instead of using harmful X-rays, this innovative technology employs signals in the 200 GHz to 400 GHz range, enabling smartphones to penetrate through dust, dense fog, and airborne particles that typically obstruct light.

Recent tests have successfully demonstrated the ability to look through cardboard sheets, and researchers are optimistic about achieving instantaneous imaging capabilities in just a few years.

While the current prototype requires objects to be placed within an inch of the device, future advancements aim to extend the scanning range, ensuring privacy and preventing misuse.

Dr. O remains optimistic about the technology’s potential, stating, “The fundamental technology is there. I’d really like to make it so it’s for everybody.”
