Electronic tattoo to enable blood pressure measurements

Researchers have developed an electronic tattoo that continuously measures blood pressure. It is expected to surpass all previous systems in accuracy.

Technology has been a game changer in medicine for years. While in our everyday lives we mainly see advances in technical devices and applications, artificial intelligence (AI) is also gradually moving into many hospitals and medical practices.

Many systems are achieving amazing results, as new technologies and AI are making classic healing and diagnostic methods even safer and more efficient in some cases. One recent example comes from the University of Texas at Austin and Texas A&M University.

Researchers have developed an electronic tattoo that will revolutionize the diagnosis of cardiovascular problems. That's because collecting reliable data on blood pressure is considered a critical factor in heart health, but has proven complicated for decades.

Electronic tattoo enables more accurate diagnoses

In most cases, previous methods only collected data at the time of measurement. Patients came in for a checkup, and doctors measured their blood pressure and analyzed the results. But depending on the time of day and the situation, our blood pressure varies and so does our health.

However, the electronic tattoo is supposed to provide a remedy. However, it does not go under the skin like a classic tattoo. Instead, they are virtually weightless sensors that envelop the skin with the help of a sticky mass.

The built-in sensors in turn send electric shocks through the body and continuously collect data. In the end, an overall picture can be derived from the individual measurements.

Smartwatches are still no serious competition

The tattoo is also made of graphene. The material is particularly thin and resistant, while at the same time its properties allow it to be worn comfortably on the body. With each individual measurement, an intelligent algorithm also analyzes the results and sounds the alarm if necessary.

Experts still believe it is unlikely that smartwatches will replace traditional blood pressure monitors. The measurement used here uses light and a sensor to measure the movement in the blood.

However, this method is still relatively inaccurate. In addition, smartwatches move continuously on the wrist. So the measurements are difficult to compare. The electronic tattoo, on the other hand, could become established sooner or later. The results are already so accurate that other commercially available devices can hardly keep up.
