Implantable Biosensor Can Measure Glucose in Sweat and Tears

Researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems IMS in Duisburg have developed an implantable biosensor that can measure glucose in sweat or tears obviating the need for needlesticks.  An electrochemical reaction using glucose oxidase that converts glucose into hydrogen peroxide; this concentration can be measured with a potentiostat and these measurements are used to calculate the glucose level. This biosensor has incorporated the entire diagnostic circuit into a fully implantable tiny sensor.  The biosensor can transmit the data via a wireless interface to a mobile receiver or even smart phone.
