The Problem

Hundreds of millions of people suffer from high blood pressure and have to monitor and measure their blood pressure repeatedly or even permanently. They all suffer from the previous method with cuff, which is not applicable everywhere and causes extremely unpleasant pressure pain. A solution to this problem would make a decisive contribution to improving the quality of life of all these people.

So far, however, despite great efforts, it has not yet been possible worldwide to develop a solution for continuous cuff-free non-invasive pulse wave blood pressure monitoring. Wrist-based pulse wave frequency monitoring has been available for almost ten years. Noise and artifact filtering has improved considerably over time. However, the step from frequency measurement to filtered force measurement and thus the acquisition of relative/absolute blood pressure values (mmHg) is still pending. This is the only way to obtain data that is precise enough for the diagnosis of medical therapies.

Our Solution

By means of a combination of established and disruptive sensor technologies we want to master this chal-lenge in continuous vital function measurement. We have developed a novel methodical approach to moni-toring using Soft Body Dynamics. Together with traditional sensor technology for the measurement of primary signals, environmental and motion artifacts, the calibration of completely refined continuous resistance signals (mV) to blood pressure readings (mmHg) becomes a feasible goal.

State of Realisation

After completion of initial clinical tests, the focus was placed on the development of soft-body dynamics detection, a key factor in the continuous monitoring of vital signs. Once the project is fully funded, the design and production of new sensor fusion prototypes and extensive testing and regulatory validation procedures are planned. The time to market is estimated to be about 48 months after the new prototype devices have been built.
