Science catches up with science fiction as we talk to Professor John Rogers, the inventor of epidermal electronics — tiny, bendy computer chips that can be placed on or in the human body to monitor critical health data. On Tuesday evening, Rogers is appearing at the Chicago Council on Science and Technology to give a talk about Body & Machine: Epidermal Electronics at Northwestern University’s Chicago Campus. The live stream begins at 6:00 pm and a link to the video will be available after the event.

In the following web extra video, you can see how the technology works. It can be applied like a Band-Aid or underneath a temporary tattoo.
