This is the first wearable device that monitors cardiovascular signals and several biochemical
Such a device is intended in particular forpeople with high blood pressure, diabetes or a predisposition to severe COVID-19. It can also be used to detect sepsis, a sudden drop in blood pressure accompanied by an increase in lactate levels.
This patch will become an alternative for patientsin intensive care units, such as infants who need constant monitoring of blood pressure and other vital signs.
Currently, these procedures take place only after the insertion of catheters, and patient indicators are monitored on several monitors.
The novelty here is that we takecompletely different sensors and combine them together on one small platform. We can collect so much information using this wearable device. And, importantly, this happens in a non-invasive way, without discomfort.

A patch is a thin sheet of elasticpolymers that adhere to the skin. It is equipped with a blood pressure sensor and two chemical sensors - one measures lactate (a biomarker of exercise), caffeine and alcohol in sweat, and the other measures glucose levels in interstitial fluid.
