Analysis
This paper introduces a novel, non-electrical approach to cardiovascular monitoring using nanophotonics and a smartphone camera. The key innovation is the circuit-free design, eliminating the need for traditional electronics and enabling a cost-effective and scalable solution. The ability to detect arterial pulse waves and related cardiovascular risk markers, along with the use of a smartphone, suggests potential for widespread application in healthcare and consumer markets.
