This Smart Bandage Can Take Your Temperature and Administer Medicine

A group of scientists at MIT have developed a futuristic hydrogel Band-Aid-like device that can incorporate a range of sensors and electronics. The versatile, programmable dressing will allow doctors to treat a range of injuries, continuously monitor a patient’s temperature and even release medicine when needed.

According to MIT, the stretchy hydrogel bandage—created by MIT professor Xuanhe Zhao and a team of graduate students—is made mostly of water and “was designed to bond strongly to surfaces such as gold, titanium, aluminum, silicon, glass, and ceramic.” The hydrogel is flexible enough that it can be applied to most body parts, including elbow and knee joints, and it can be outfitted with electronics programmed to release medicine at intervals or when a patient’s temperature rises.

“Electronics are usually hard and dry, but the human body is soft and wet. These two systems have drastically different properties,” Zhao says. “If you want to put electronics in close contact with the human body for applications such as health care monitoring and drug delivery, it is highly desirable to make the electronic devices soft and stretchable to fit the environment of the human body. That’s the motivation for stretchable hydrogel electronics.”

Photo of Billy the Kid and Pat Garrett, Purchased for $10, Could Be Worth Millions

Several years ago, Randy Guijarro paid $2 for a few old photographs he found in an antiques shop in Fresno, California. In 2015, it was determined that one of those photos—said to be the second verified picture ever found of Billy the Kid—could fetch the lucky thrifter as much as $5 million. That story now sounds familiar to Frank Abrams, a lawyer from North Carolina who purchased his own photo of the legendary outlaw at a flea market in 2011. It turns out that the tintype, which he paid $10 for, is thought to be an image of Billy and Pat Garrett (the sheriff who would eventually kill him) taken in 1880. Like Guijarro’s find, experts say Abrams’s photo could be worth millions.

The discovery is as much a surprise to Abrams as anyone. As The New York Times reports, what drew Abrams to the photo was the fact that it was a tintype, a metal photographic image that was popular in the Wild West. Abrams didn’t recognize any of the men in the image, but he liked it and hung it on a wall in his home, which is where it was when an Airbnb guest joked that it might be a photo of Jesse James. He wasn’t too far off.

Using Google as his main research tool, Abrams attempted to find out if there was any famous face in that photo, and quickly realized that it was Pat Garrett. According to The New York Times:

Then, Mr. Abrams began to wonder about the man in the back with the prominent Adam’s apple. He eventually showed the tintype to Robert Stahl, a retired professor at Arizona State University and an expert on Billy the Kid.

Mr. Stahl encouraged Mr. Abrams to show the image to experts.

William Dunniway, a tintype expert, said the photograph was almost certainly taken between 1875 and 1880. “Everything matches: the plate, the clothing, the firearm,” he said in a phone interview. Mr. Dunniway worked with a forensics expert, Kent Gibson, to conclude that Billy the Kid and Mr. Garrett were indeed pictured.

Abrams, who is a criminal defense lawyer, described the process of investigating the history of the photo as akin to “taking on the biggest case you could ever imagine.” And while he’s thrilled that his epic flea market find could produce a major monetary windfall, don’t expect to see the image hitting the auction block any time soon. 

"Other people, they want to speculate from here to kingdom come,” Abrams told The New York Times of how much the photo, which he has not yet had valuated, might be worth. “I don’t know what it’s worth. I love history. It’s a privilege to have something like this.”
