Sensifree, founded in 2012, has a contact free, electromagnetic sensor that it claims can collect a range of continuous biometric data without needing to touch the human body. The technology uses RF signals to sense movement in the radial artery wall to track heart rate and, potentially, blood pressure. Having taken the pulse as a digital signal subsequent processing is used to extract more information. The technology consumes about 10 percent of the power of optical methods and operates through fabrics, the company claims.
"We believe that CSEM will be key in our endeavors to develop the 'holy grail' of sensors, a cuff-free blood pressure sensor," said Eran Agmon, co-founder and CEO of Sensifree, in a statement. Ilan Barak, Sensifree’s co-founder and CTO added: "We have strategically decided to collaborate with CSEM because of its solid and internationally acknowledged background in non-obtrusive blood pressure estimation."
