Implanted Diabetes Chip Promises Precise Blood Sugar Monitoring

Diabetics may soon have a new high-tech, needle-free option for tracking their blood sugar. Swiss researchers have developed an implantable chip that can monitor blood sugar in diabetics as effectively as glucose monitors that rely on blood drawn from needle sticks.

The tiny chip, about a half-inch square, was successfully tested on mice at the Institute for Research in Biomedicine (IRB) in Bellinzona, Switzerland, provides constant analysis of glucose levels, as well as cholesterol, drugs, and other components in blood.

"This is the world's first chip capable of measuring not just pH and temperature, but also metabolism-related molecules like glucose, lactate and cholesterol, as well as drugs," said Sandro Carrara, who led the research team that developed the device.

Dr. Carrara said the device — unveiled this week at the International Symposium on Circuits and Systems (ISCAS) in Lisbon — can monitor to a wide range of compounds, and it can do so for several days or even weeks.

It contains three main components: a circuit with six sensors, a control unit that analyses incoming signals, and a radio transmission module. It also has an induction coil that draws power from an external battery attached to the skin by a patch.

"A simple plaster holds together the battery, the coil and a Bluetooth module used to send the results immediately to a mobile phone," said Dr. Carrara.

The research team predicts clinical tests of the device in humans could take place in three to five years.

"Knowing the precise and real-time effect of drugs on the metabolism is one of the keys to the type of personalized, precision medicine that we are striving for," said Dr. Carrara.
