Rockley Photonics Holdings has announced the successful completion of the first human studies trial for its biomarker sensing platform. Future VitalSpex modules should be able to non-invasively provide data about biomarkers such as blood alcohol content, blood pressure, and blood sugar. Rockley is also known for its association with Apple.

Is the study with 40 subjects published in any peer reviewed journals? I am very interested in reading further and proof of concept for the wearable non-invasive glucose monitor.
This is an unapproved medical device. The trials are what matter, and if they really are attempting to offer this as a medical grade diagnostic instrument the trials data is where we would find the information, not peer reviewed journals.
The tech behind these devices, however, has hopefully made journal rounds.
