With recent advances being made in flexible electronics, researchers are finding more and more ways to adapt medical devices to the human body. These include smart tattoos, stretchable patches for organs, and even implants. But what of band-aids? Aren’t they about due for an upgrade? Well as it happens, a team of chemical engineering at Northeastern University are working towards just that.
Led by associate professor Ed Goluch, the team is working towards the development of a “smart bandage” that will not only dress wounds, but can monitor infections and alert patients to their existence. Based around an electrochemical sensor that is capable of detecting Pseudomonas aeruginosa – a common bacteria that can kill if untreated – this bandage could very prove to be the next big step in first aid.
I was designing sensors to be able to track individual cells, measure how they produce different toxins and compounds at the single-cell level and see how they change from one cell to another and what makes one cell more resistant to an antibiotic.
Naturally, addition research is still needed so that smart band-aids of this kind would be able to detect other forms of infections. And Goluch and his colleagues are quite confident, claiming that they are adapting their device to be able to detect the specific molecules emitted by Staphylococcal – the bacteria responsible for staph infections.
So far, Goluch and his team have tested the system with bacteria cultures and sensors. The next step, which he hopes to begin fairly soon, will involve humans and animals testing. The professor isn’t sure exactly how much the sensor would cost when commercialized, but he believes “it’s simple enough that you’d be able to integrate it in a large volume fairly cheap.”
At this rate, I can foresee a future where all first-aid devices are small patches that are capable of gathering data on your wounds, checking your vitals, and communicating all this information directly to your PDA or tablet, your doctor, or possibly your stretchable brain implant. I tell ya, it’s coming, so keep your apps up to date!
