According to foreign media reports, Rockley Photonics ( Rockley Photonics , a sensor manufacturing company that cooperates with Apple to produce Apple Watch ) announced that its first phase of human research on detecting blood pressure with wristband sensors has achieved preliminary results, or it is possible to provide a new non-invasive blood pressure detection method for cardiovascular health management. The company's researchers demonstrated that its sensors use new laser technology and AI algorithms to complete noninvasive blood pressure detection without the need for a sphygmomanometer cuff.
In addition to the research of non-invasive blood pressure detection technology, Rockley's core body temperature detection technology has also made progress, and the success of these studies has improved the health detection function of Rockley's sensors, verified that the research direction of its health detection solutions in the sensing method is correct, and helped expand the health detection range of wristband sensors to further meet the health management needs of the public.
At present, Rockley has established cooperation with 12 consumer electronics manufacturers and 5 medical equipment companies, and smart watches are expected to be equipped with sleeveless and non-invasive blood pressure detection functions. Wall Street news said that Apple plans to add more sensing functions to the Apple Watch, including detecting breathing, low blood oxygen levels and diabetes, of which diabetes is particularly closely related to blood pressure.
First, the first phase of human experiments has been completed, and the sleeveless and non-invasive blood pressure detection function is expected to be realized
Recently, Rockley announced that the company has completed the first phase of human research using Rockley wristband sensors for blood pressure monitoring, and Hooman Abediasl, the company's senior vice president of product engineering, claimed that the company's preliminary research results on using the wrist to detect blood pressure are very "encouraging.".
The wristband sensor used in the study employs a unique laser-based non-invasive measurement method and uses Rockley's advanced algorithms in cloud computing and AI. The experiment first used an upper-arm sphygmomanometer to detect the subject's blood pressure, and then used the Rockley sensor and the sensor using the mainstream PPG technology (photoplethysmography, photoplethysmography) sensor to detect the health of the subjects, and after comparing the data of the two, the data of the Rockley sensor can be found to be more accurate.

Moreover, Rockley wristband sensors do not require the use of an upper arm cuff for assisted detection when measuring blood pressure. Prior to this, Samsung said that its galaxy Watch 3 released can detect blood pressure through PPG technology, but also requires upper arm cuffs to assist detection, while Rockley wristband sensors are more portable.
Second, sensing technology combined with AI, the detection range is expanded to the core body temperature and other aspects
Rockley's wristband sensors improve the accuracy of sensing technology in blood pressure detection, while enabling high-speed, high-volume transmission of human health data. At present, Rockley has not publicly released relevant results in the field of AI, but the company has issued a positive opinion, believing that the combination of sensing technology and AI technology can further meet the needs of public health management.
In addition to blood pressure detection, Rockley claims that the company's wristband sensors are able to determine the relationship between heart rate (HR) and heart rate variability (HRV), detecting core body temperature, body hydration, alcohol levels, lactate and glucose levels, and more. According to Human Abidiso, the findings validate the effectiveness of the company's sensing solutions and can further drive the production of lightweight, portable wristband health management devices with a wide range of tests.
Third, the intelligent health management market is attractive, and consumer electronics and medical equipment companies have set foot
Currently, Rockley is gaining high attention in both the consumer and medical technology market segments with the sensors it has released. To date, Rockley has partnered with 12 consumer electronics manufacturers, including six of the top 10 companies in the wearables segment, and Rockley has partnered with 5 medical device companies, including two of the top 10 companies in the medical device space. Apple, as a US technology giant, also attaches importance to increasing the health detection function of its smart watch product Apple Watch, according to the Wall Street Journal, Apple hopes to achieve low blood oxygen, fertility and even diabetes detection through apple Watch.
Andrew Rickman, CEO and founder of Rockley, added: "For a growing customer base, demonstrating wristband blood pressure detection capabilities was critical to the development of our biosensing platform... Both consumers and the healthcare industry understand that wristband health detection sensors will have a huge impact on the health management of individuals. ”
Conclusion: The public pays attention to intelligent health management, or can expect the early warning function of major diseases
At present, smart watches have been able to monitor sleep, monitor heart rate, sedentary reminders and other functions, and even diagnose abnormal conditions such as arrhythmias and atrial fibrillation, Rockley's research results in blood pressure detection will further expand the function of smart watches in health detection to meet the health management needs of the public.
In response to the public's concern about health management, smart watches, a sensitive and portable health management device, have been increasingly valued by companies in the field of consumer electronics. Technology giants such as Apple and Samsung have set foot to expand the health detection function of smart watches. At present, Huawei has realized the blood pressure detection function of smart watches through pressure airbags, and Rockley has explored the possibility of measuring blood pressure with smart watches with the help of laser technology. In the future, whether smart watches can break through the conventional range of health management such as sedentary reminders and sleep monitoring, and realize the early warning of major diseases such as diabetes, it is worth looking forward to.
