Comprehensive “clinic-on-the-wrist” digital health sensor system debuts. Apple Watch of future? (UK/US)

The likely future of the Apple Watch and medical monitoring. Rockley Photonics, a silicon photonics company based in Oxford England and Pasadena, has debuted a sensor module that can enable wearable devices to monitor multiple biomarkers, including core body temperature, blood pressure, body hydration, alcohol, lactate, and glucose trends, among others. The module (exterior above far left and mid-right) combines with hardware and application firmware for consumer applications, such as wrist-worn diagnostics.

The mid-left-hand view shows the reverse (skin) side of the module with the photonic ICs and application firmware. Current sensors use green-light emitting diodes (LEDs) and the Rockley system uses an infrared (IR) spectrophotometer that generates a large number of discrete laser outputs from a single silicon chip covering a broad optical band which can penetrate underneath the skin. The module communicates with custom cloud-based analytical engines via a Rockley smartphone app (far right).  

Obviously, Rockley is seeking to commercialize this through partnerships with consumer electronics companies in digital health and fitness monitoring. Rockley is a key supplier to Apple for sensors. Release, FierceHealthcare 

Financially, on 9 August they closed their SPAC with SC Health Corp. of Singapore after the UK courts approved the business combination. As of 13 August, it is trading on the NYSE as Rockley Photonics Holdings, Ltd. (RKLY). Rockley received $167.8 million in gross proceeds, including $17.8 million from SC Health, as well as $150 million from the financing completed in connection with the announcement of the business combination, led by top-tier institutional investors including Senvest Management LLC and UBS O’Connor and participation from Medtronic. According to their 22 July shareholders letter, all their revenue is attributable to two companies: Apple and Hengtong Rockley, a Chinese joint venture, and an accumulated deficit of $298 million.   Release
