Abstract: A garment to be worn directly on the upper body of a person is formed from fabric and includes a flexible printed circuit board and a number of mounting points for electrocardiogram (ECG) electrodes to which ECG electrodes can be releasably attached. For each mounting point, a wire is embedded in the fabric. Each of the wires can electrically connect an ECG electrode attached to the respective mounting point to the flexible printed circuit board. The flexible printed circuit board includes processing circuitry configured for evaluating signals received via the wires from ECG electrodes attached to the mounting points to obtain results and further configured for transmitting the results to an external receiver. A system can include a garment and an external receiver in the form of a mobile device.

Abstract: Disclosed is a method for measuring an arterial blood pressure of a subject comprising detecting a pulse-wave-related signal of the subject; extracting a feature from the signals; determining a factor that can affect the arterial blood pressure of the subject; and determining the arterial blood pressure based on the feature with an automatic compensation for the factors. The disclosed method reduces the error in measuring the blood pressure based on characteristics of the pulse-wave-related signals.
