Title:
検体測定パッチ
Document Type and Number:
Japanese Patent JP6735853
Kind Code:
B2
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 (101), a counter electrode (103) and a reference electrode (102). The patch further includes an electronics unit with a microcontroller (1200) and a current measurement unit. The microcontroller (1200) includes a control output (DAC), a first analogue input (ADC-1) and a second analogue input (ADC-2). The control output (DAC) is operatively coupled with a control electrode, the control electrode being either of the working electrode or (101) or the counter electrode (103). The first analogue input (ADC-2) is operatively coupled with a measurement electrode via the current measurement unit, the measurement electrode being either of the working electrode (101) or the counter electrode (103). The second analogue input (ADC-1) is operatively coupled with the reference electrode (102). The microcontroller (1200) is configured to control, by providing a control voltage to the control output (DAC), a potential difference between the working electrode (101) and the counter electrode (103) to equal a predefined polarization voltage.
