iPhone 4 and a sensor tattoo creates diabetic blood monitor
Diabetics have a problem dealing with sugar because they don’t produce enough insulin (Type 1) or any insulin that is produced gets no reaction from the person’s cells (Type 2). Treatment is mainly through the management of blood sugar levels which if done properly can stop many of the complications.
It’s the monitoring of those blood sugar levels that researchers are working towards making as simple and fast as possible, and the latest idea involves the use of a sensor tattoo and an iPhone 4.
Rather than having to take a blood sample Dr. Heather Clark of Northeastern University has come up with a method that can give instant feedback on levels of sodium, glucose, and alcohol in a person’s blood just by looking at a set of sensors under the skin.
The sensors are only 100nm wide and get placed under the skin just like tattoos are. Nanoparticles in the sensors attach to different aspects of the blood and have a color-changing effect on the sensor. Doing that for sodium, glucose, and alcohol presents three specific colors that tell you their current levels.
