Abstract
A measuring apparatus used for determining an analyte in a liquid sample has the following apparatus components: a test element with a test field for applying the liquid sample, the test element experiencing a detectable modification due to the analyte to be determined, a detector which detects the modification and generates an electrical detector signal as a function of it, an evaluation circuit arranged downstream of the detector, which evaluates the detector signal to form a measurement result, a display device connected to the evaluation circuit for displaying the measurement result, and an electrical power supply for supplying electrical power to the electrical apparatus components.
So that the analyte can be determined in a straightforwardly, conveniently and inexpensively, at least some of the electrical apparatus components (5 to 12) are formed on the basis of polymer electronics.
