Apple provider Rockley Photonics unveiled a complete well being sensor system that may assist convey steady non-invasive blood sugar measurement to a future Apple Watch.


  • Rockley Photonics launched its new digital well being sensor system
  • It could measure blood sugar ranges and extra, non-invasively
  • Apple might undertake this expertise for a future Apple Watch

Rockley might assist convey new Apple Watch well being options

The British electronics startup, which has an ongoing provide and growth settlement with Apple, wrote in a press launch on the Rockley web site that its new digital well being sensor system is like having a clinic on the wrist. It’s able to non-invasive blood sugar measurement, amongst different issues, a holy grail for treating diabetes and life sciences.

The sensor system permits the monitoring of different biomarkers concurrently, together with core physique temperature, blood strain, physique hydration, alcohol, lactate and glucose tendencies. The corporate will launch a wristband that accommodates the sensor module and works with a smartphone app to ship varied well being insights.

Reference designs together with the brand new sensors shall be made accessible to shoppers subsequent yr. If Apple decides to make use of Rockley’s expertise to allow non-invasive blood sugar measurement on a future Apple Watch, then it sounds just like the function will debut in Apple Watch Sequence 8 in 2022 moderately than the upcoming Sequence 7 mannequin releasing this fall.

About Rockley’s spectroscopy expertise

Rockley focuses on non-invasive optical sensors for detecting blood strain, physique temperature, blood glucose and alcohol ranges and extra. Much like the optical coronary heart price sensor constructed into the Apple Watch’s again crystal, Rockley’s sensor makes use of infrared mild to detect the aforementioned metrics by way of your pores and skin.

From the press launch:

Whereas lots of at this time’s wearable shopper digital gadgets use inexperienced light-emitting diodes to watch coronary heart price, Rockley’s infrared spectrophotometers can detect and monitor a a lot wider vary of biomarkers, which might dramatically improve the performance of wearable gadgets.

Primarily based on Rockley spectroscopy expertise, the sensor module takes benefit of a lot of discrete laser outputs from a single silicon chip to cowl a broad optical band, permitting it to watch a number of essential blood-related metrics frequently.

The sensor non-invasively probes beneath the pores and skin to investigate blood, interstitial fluids and varied layers of the dermis for constituents and bodily phenomena of curiosity. Such biomarkers have traditionally been measurable solely by utilizing bench-top gear.

The Telegraph reported in Might 2021 that Rockley will go public on the NYSE later this yr beneath the image RKLY, with Apple accounting for a overwhelming majority of its income in 2020 and 2019. In accordance with a June 2021 report from Bloomberg, a non-invasive blood glucose sensor is a number of years away from being shipped in an Apple Watch.

The truth is, Apple could also be engaged on comparable non-invasive well being sensors of its personal.
