Abstract
Disclosed are a system and a method for noninvasively and continuously monitoring blood pressure. Also disclosed is a method for making such a device. The system includes a semiconductor chip comprising a transducer array of individual pressure or force sensors and associated circuitry providing control signals to and/or processing signals from these sensors, all of the above integrated in the chip. Also disclosed is a specific sensor structure provided on said chip. The invention further encompasses a system for measuring and/or tracking the blood pressure waveform and for combining the latter with related blood values like the heartbeat, derived from the above or other measuring devices.
