Say goodbye to burns, insulin jabs: New smart bandage can medicate chronic skin wounds

NEW YORK: Researchers have developed a prototype bandage designed to actively monitor the condition of
chronic wounds and deliver appropriate drug treatments to improve the chances of healing.

While the lab-tested bandages remain to be assessed in a clinical context, a study, published in the journal Small, said the aim is to transform bandaging from a traditionally passive treatment into a more active paradigm to address a persistent and difficult medical challenge.

According to the researchers, chronic skin wounds from burns, diabetes and other medical conditions can overwhelm the regenerative capabilities of the skin and often lead to persistent infections and amputations.

“We have been able to take a new approach to bandages because of the emergence of flexible electronics,” said co-author Sameer Sonkusale, Professor at Tufts University in the US.

The researchers designed the bandages with heating elements and thermoresponsive drug carriers that can deliver tailored treatments in response to embedded pH and temperature sensors that track infection and inflammation.

They said that pH of a chronic wound is one of the key parameters for monitoring its progress. Normal healing wounds fall within the range of pH 5.5 to 6.5, whereas non-healing infected wounds can have pH well above 6.5.

Temperature is also an important parameter, providing information on the level of inflammation in and around the wound, they added.

While the smart bandages in this study combine pH and temperature sensors, the team have also developed flexible sensors for oxygenation — another marker of healing — which can be integrated into the bandage.

Inflammation could also be tracked not just by heat, but by specific biomarkers as well, the researchers said.

A microprocessor reads the data from the sensors and can release drug on demand from its carriers by heating the gel.

The entire construct is attached to a transparent medical tape to form a flexible bandage less than 3 mm thick. Components were selected to keep the bandage cheap and disposable, except for the microprocessor, which can be re-used.

The researchers noted that smart bandages could provide real time monitoring and delivery of treatment with limited intervention from the patient or caregivers.

Stranger Things: Weird Tech From CES 2018

Bizarre Tech

19 Jan, 2018

From pole dancing robots to weight loss headsets, the biggest electronics show was not short on the weird quotient either.

CES is home to some of the hottest gadgets and technologies of the year. But there’s always a fair amount of weird tech that graces the show floor. Beyond VR experiences and cute robots, these oddball products and concepts also garnered a lot of attention this year:

Somnox Robotic Pillow

19 Jan, 2018

Therapeutic sleep aids are nothing new, but Somnox robotic pillow is different. It claims to soothe you to sleep. The huggable robot synchronises its movement with your breathing rhythm, plays lullabies and lets you sleep feeling safe.

Toyota e-Palette Concept

19 Jan, 2018

The age of autonomous cars is going to be interesting. Toyota’s e-Palette Concept visualises the future as a mobility eco-system that involves autonomous vehicles roaming through cities with customisable interiors depending on a specific task. It can be your mobile hotel room, retail store, restaurant, flea market, lounge etc.

Modius Headband

19 Jan, 2018

Here’s a shortcut to losing weight in 2018 — a Modius headband. It claims to stimulate your vestibular nerve for an hour every day to make you feel less hungry and convince your body to start burning fat. The app tracks your progress like weight changes, body fat reduction, BMI, and waist inches.

L’Oréal UV Sense

19 Jan, 2018

Sunscreens are passé. The CES showed us the first battery-free wearable electronic UV sensor, the UV Sense. It’s a tiny nail sticker that tracks how long you’ve been out in the sun and informs real-time about your ultraviolet (UV) exposure levels. The sensor comes with replaceable adhesives, and can be snapped onto other items as well.
