The apparatus for the non-invasive glucose detection comprises an electrical detection device (2) for measuring the response of the tissue or blood to an electric field at low frequencies below 1 MHz and at high frequencies above 10 MHz. The former is primarily dominated by skin hydration and sweat, while the latter contains contributions from the current glucose level. Combining the two signals allows an increased degree of accuracy. The apparatus further comprises a force or acceleration sensor (4, 5), which allows to detect the pressure of the apparatus against the skin and/or quick movements. Further sensor modules, such as a temperature sensor (6) or alternative perfusion sensor (7), improve the accuracy of the measured result.
