"Smart" Bandages That Track And Treat Wounds

Excited for the August 21 eclipse? Visit our Eclipse 2017 page to explore the science, history, and myths of the event. The Curiosity team will be viewing the eclipse alongside NASA in Carbondale, Illinois. Follow us on Facebook for live videos, trivia, and interviews on the big day.

Engineers are taking band-aids to the next level. MIT engineers are creating the bandage of the future. Though the original design of the Band-Aid hasn't changed much since its 1920 invention, the "smart" bandage is more like a long-lasting, high-efficiency human body electronic device than your traditional bandage. These bandages will be made from stretchable hydrogel, and will include technology that can monitor wounds, administer drugs, and even alert a doctor when more medicine is needed. The hydrogel mimics the feel and capabilities of human skin for a comfortable, long-term fit. Inserted in the bandage are LED lights attached to the sensors, that will light up when a wound reaches a concerning temperature. In the future, the engineers are hoping to create probes to actually go inside the brain and body.
