[Increased knowledge] How to use “light” to sense “invisible risks” in advance?

According to the "China Cardiovascular Health and Disease Report" recently released by the National Center for Cardiovascular Disease, the prevalence of hypertension in my country has shown an overall upward trend in recent years. The prevalence of hypertension among residents aged 18 and above is 31.6%, while the awareness rate of hypertension is only 43.4%. In this context, how to promptly detect hypertension problems, effectively control blood pressure levels, and reduce cardiovascular risks has become an important issue in people's health management.

To prevent "stress" before it occurs, health monitoring starts from the "heart"

Relevant studies show that increased heart rate is a common clinical phenotype of hypertension. In daily health management, wearable devices such as smart watches and smart bracelets can help people sense abnormal risks in the body in advance through real-time feedback of vital sign data such as heart rate, and provide reference clues for early attention and early screening of hypertension.

Photoelectric sensing devices are important components for health monitoring in wearable devices. This device is based on photoplethysmography (PPG), which uses LEDs to emit light signals and PDs to receive reflected light signals to complete photoelectric conversion. It is the underlying technical basis for wearable devices to non-invasively obtain heart rate, blood oxygen and other parameters.

Three major scenarios, perceiving health starts from "light"

As an innovation promoter in the field of LED packaging, Nationstar Optoelectronics, a listed company controlled by Guangsheng Holding Group, is deeply involved in the photoelectric sensing technology of wearable devices, and has launched intelligent sensing product solutions suitable for terminal devices such as smart watches, smart bracelets, smart rings, smart headphones, etc., to help people build a solid health monitoring defense line with a multi-scenario layout.

Smart watches/bracelets: health stewards on the wrist

Focusing on the current mainstream smart watches, bracelets and other health monitoring products, Nationstar Optoelectronics has launched a series of high-precision smart sensing solutions. With performance advantages such as small-angle light emission and strong anti-interference, it provides strong optoelectronic technology support for terminal equipment to accurately collect vital sign data.

Smart Ring: Precise sensing on fingertips

Aiming at the emerging application of smart rings, which are small, portable and non-sensory to wear, Nationstar Optoelectronics has launched a miniature series of smart sensing solutions. The 2522 receiver used in it reduces its size by more than 15% while maintaining the same photosensitive area. It has high precision, low power consumption and easy integration, and can be flexibly adapted to small wearable devices such as smart rings.
