On: Cuffless device delivers clinically accurate blood...

Any idea how this BP device actually works? Is it optical? How is it possible to measure without a cuff?

I guess this is the underlying tech: https://www.leman-micro.com/wp-content/uploads/2020/11/LMD-W...

So the pressure is just measured with a MEMS (microelectromechanical) device, the temperature with a different one, and there's also a pulse oximeter (optical).
