Rockley PhotonicsRockley Photonics recently went public through a merger with a special-purpose acquisition company called SC Health Corp.

The Oxford, U.K.–based maker of silicon photonics technology started trading on the New York Stock Exchange under the symbol RKLY. It plans to use the roughly $168 million from the deal to accelerate the launch of its “clinic-on-the-wrist” digital health sensor system, which the company claims can continuously track a host of metrics including core body temperature, blood pressure, body hydration, alcohol, lactate and glucose.

Rockley Photonics has combined hardware and application firmware in a module for OEM manufacturers — with the option of adding cloud analytics for certain clinical/medical partnership applications.

“Silicon photonics has tremendous potential to transform multiple industries through a broad range of applications, particularly in the health and wellness space by bringing laboratory-grade measurement on the wrist much closer to reality,” Rockley Photonics CEO Andrew Rickman said in an Aug. 11 news release. “As we continue on the next phase of our growth as a public company, we are in a much stronger position to create solutions that can provide a new class of actionable insights, transform digital healthcare, and deliver life-changing benefits to people across the globe.”
