Abstract: The invention relates to measuring blood pressure and the calibration of said measurement. Here, the intention is to specify solutions which facilitate a more accurate and/or less burdensome measurement. To this end, it is proposed to take pressure measurements in certain respiratory states and/or to undertake the calibration by means of pressure variations without physical activity, i.e., on account of respiration or changes in position, and/or separately for systolic pressure and diastolic pressure.

Abstract: A time-resolved measurement of blood pressure, arterial elasticity, pulse wave, pulse wave transit time and pulse wave velocity, a cardiac output, and/or changes in cardiac output of a human or animal body, using a pressure sensor unit while being pressed against the skin. The unit is an air and/or gas pressure sensor, and is configured to change at least one electrical conductance and/or resistance when subjected to pressure. The unit has at least two conductor trace arrays, particularly conductor trace networks, and a functional polymer that is compressed when subjected to pressure, and produces and/or alters contact between the conductor trace arrays. Alternatively, the unit has at least two conductive layers with a gap therebetween, and is configured such that the gap becomes compressed when subjected to pressure, and/or such that the capacitance of the assembly composed of the two conductive layers is changed as a result.

Abstract: A method for determining vital parameters of a human body using a device with at least one optical recording unit and a computing unit includes the following steps: recording a sequence of individual image data of a single limited area of the skin of the human body using the optical recording unit; evaluating the image data, including determining a pulse wave transit time; and determining vital parameters of the human body from the image data using the computing unit. Further, a device determines vital parameters. In addition, a method authenticates a person and a method identifies a reaction of a person.
