TECHNOLOGY OVERVIEW

Abnormalities in blood pressure are often an indicator of illnesses. The current gold standard for blood pressure measurement is through the use of a cuffed sphygmomanometer. Such traditional cuff systems for blood pressure measurements have many disadvantages. Not only are they uncomfortable, they also do not allow for continuous blood pressure measurements which is important for the accuracy of diagnosis of chronic hypertension. In critically ill patients where continuous blood pressure monitoring is required, only invasive methods are used which could have implications such as infection and ischemia. 

To address this, a non-invasive blood pressure wearable consisting of several chest-based sensors including continuous wave radar, PPG and some others which allows for continuous blood pressure measurement is developed. 

TECHNOLOGY FEATURES & SPECIFICATIONS

This device allows for the calculation of several hemodynamic parameters via the placement of the sensors on the sternum. Thereafter, the blood pressure, pulse transit time and pre-ejection period can be estimated. Compared with PPG sensors, the CWR sensors enables a low power, continuous and direct monitoring of aortic valve activities with minimal body contact.

This non-invasive and less cumbersome technique allows for continuous monitoring during rest and exercise. It has been tested in a group of 43 volunteers and has an accuracy of 93% and 83% for those completing posture tasks and during exercise respectively.

POTENTIAL APPLICATIONS

  • Blood pressure monitoring
  • Vital signs monitoring 

Benefits

Doctors will be able to use the information obtained from the wearable sensors to better diagnose their patients. Patients will be able to continuously monitoring their health (i.e. blood pressure) via this non-invasive wearable device.
