A prick of the pin for a drop of blood isn't so simple for diabetics with hemophobia--it's more like a starring role in the "Saw" trilogy. Damian Mackiewicz, an an industrial design student from the University of Applied Science in Schwaebisch Gmuend, Germany, has a concept that makes for wince-less glucose monitoring. Lima utilizes infrared technology that sends a light through the skin to detect sugar levels in the blood. As the infrared rays pass through the skin into the blood, it is reflected back into the sensor on Lima. The system can identify bits of glucose by the frequencies and wavelengths they transmit . It's simple to use: place the lime shaped device in the palm of your hand, push the on/off button, and wait as the scanning process begins.
