Diabetics may have yet another tool in their blood-sugar management arsenal -- an implantable, fluorescent blood-sugar monitor. It involves small hydrogel beads that vary the intensity of emitted light depending on glucose concentration. They're called Life Beans.
The system, developed at the University of Tokyo, could lead to implantable blood-glucose monitors, which could enable 24-7 monitoring of a diabetic's blood sugar without having to prick the skin or use an attachable pump.
People get tattoos for all kinds of reason, such as conveying their appreciation for Japanese calligraphy or to let others at the gym know their biceps are rugged like barbed wire. But a team of MIT researchers have found a higher calling for tattoo tech: using a nanoparticle ink to monitor glucose levels in the bloodstream.

Diabetics are finger-prickers by necessity, but a reprieve may be in store for their sore digits. A bean-size sensor, slipped under the skin and read wirelessly, could take the pain and hassle out of blood-sugar monitoring. The system “listens to the vibrations of the sensor inside you” to measure glucose levels, says the inventor, Craig Grimes, an electrical engineer at Penn State University.
