San Francisco-based start-up Blumio has developed a sensor that uses radar to make it easier and faster to measure blood pressure.
Existing monitors are impractical in today's mobile society, as they rely on inflatable cuffs that are bulky, uncomfortable and indiscreet. Blumio has developed a compact and portable sensor that provides a more convenient way for users to track their blood pressure accurately and continuously.
The sensor works by using radar to detect the pressure waves that travel through the blood vessels. It doesn't require direct skin contact – it just needs to be placed near the wrist where it can capture readings from the radial artery. The contactless sensor can be entirely encased in a number of non-intrusive ways in order to read data at any time, according to co-founder Catherine Liao.
Blumio's engineers are currently working to increase the accuracy of the sensors, and hope to start a field trial with a start-up brand accelerator in San Francisco soon. The product is likely to launch in 2017 and will cost between $200 and $400. It is primarily intended for people who know they have high blood pressure and want to track it easily over time, as well as those who have had previous health issues such as a heart attack.
