Abstract
Disclosed is an analyte measuring patch for invasive measuring a concentration of an analyte, in particular glucose. The analyte measuring patch includes a sensor with a working electrode (), a counter electrode () and a reference electrode). The patch further includes an electronics unit with a microcontroller () and a current measurement unit. The microcontroller () includes a control output (DAC), a first analogue input (ADC-) and a second analogue input (ADC-). The control output (DAC) is operatively coupled with a control electrode, the control electrode being either of the working electrode or () or the counter electrode (). The first analogue input (ADC-) is operatively coupled with a measurement electrode via the current measurement unit, the measurement electrode being either of the working electrode () or the counter electrode (). The second analogue input (ADC-) is operatively coupled with the reference electrode (). The microcontroller () is configured to control, by providing a control voltage to the control output (DAC), a potential difference between the working electrode () and the counter electrode () to equal a predefined polarization voltage.
