Ever wondered what the shining green light is doing on the underside of your smartwatch?
The green LED probes the skin to measure various health parameters - biomarkers - of the wearer. Just what light can reveal about a user’s health is a topic that has preoccupied Rockley Photonics for several years.
Rockley is not solely interested in using the visible spectrum to probe the skin but also light at higher wavelengths. Using the infrared portion of the spectrum promises to reveal more about the watch wearer's health.
Rockley can also shed light on its own healthcare activities following the announcement of its merger with SC Health that will enable Rockley to be listed on the NYSE, valued at $1.2 billion.
