Abstract: A measurement device (1) for measuring at least one vital parameter is provided. The measurement device (1) comprises a base body (2), a fixing means (10) and at least one sensor (5). The at least one sensor (5) is mounted in a damped manner, in particular actively damped, by a means for pressure regulation (7) in the base body (2), in particular in a recess (3) of the base body (2). Furthermore, a measurement system with a measurement device (1) according to the invention, a method for determining a pressure with which the sensor (5) of the measurement device lies on the skin of the patient, a method for measuring at least one vital parameter and a use of the measurement device for determining at least one vital parameter are provided.

Abstract: 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.

Abstract: A device for measuring the glucose level in living tissue has electrodes (5, 6) for being brought into contact with the specimen and a voltage-controlled oscillator (31) as a signal source for generating an AC voltage in a given frequency range. The AC voltage is applied to the electrodes (5, 6). A voltage over the electrodes is fed to a processing circuitry (37, 38), which converts it to the glucose level using calibration data. The voltage-controlled oscillator (31) has a symmetric design with adjustable gain for generating signals in a large frequency range with low distortions at a low supply voltage. The processing circuit comprises a simple rectifier network with software-based correction. The electrodes (5, 6) are of asymmetric design and optimized for biological compatibility.
