Several weeks ago, I wrote about how medical devices will be transitioning from 3-dimensional objects to 2-dimensional ones. The latest news in this area comes from UC San Diego, where researchers have developed enzyme-based inks that can be used to create low-cost, wearable sensors. The inks can be applied using a ball point pen.
Also in the news, via Kurzweilai.net, is a report about how flexible sensors could be used to allow the human body to act as an input device. In my previous post, I wrote about how these new patch/sticker-like devices will require new thinking about user interface design. The flexible sensor devices reported in Kurzweil are evidence of this thinking, and of where interface design for medical devices might be headed.
