Blood pressure measurements using a smartphone and fingertip
Biospectal is a Switzerland based startup with $4.3M of funding, partly from LabCorp. They are currently working to scale their OptiBP smartphone app worldwide, including into the United States.
How it Works
The way it works is an individual places their fingertip over the smartphone camera’s optical lens, and the OptiBP smartphone app detects and measures blood pressure flow under the fingertip. It takes about 20 seconds, which is much faster than a traditional blood pressure cuff and turns the ubiquitous smartphone into an on-demand medical device.
Their software is based upon 10 years of non-invasive optical biosensing R&D and 5 years of validation at CSEM, the Swiss Center for Electronics and Microtechnology.
