NATIONSTAR Launches 4th-Generation Intelligent Health Sensing Solution

With the accelerating pace of life, health issues have received growing attention. Wearable devices represented by smartwatches have become ideal "helpers" for personal health management thanks to their health monitoring functions, and are also a key focus for major hardware manufacturers.

As a core component enabling health monitoring on wearables, photoelectric sensors convert optical signals to electrical signals and then to digital signals, helping devices collect health data.They play a crucial role in ensuring the accuracy and comprehensiveness of data output.

Comprehensively Enhanced Sensing Capability

NATIONSTAR Unveils New Intelligent Health Sensing Solution

In the smart wearable sector, leveraging its leading advantages in LED packaging technology, NATIONSTAR has long deployed a series of high-performance health sensing products with cutting-edge technology.

Recently, NATIONSTAR launched its 4th-generation intelligent health sensing solution. By upgrading device structure design, optimizing packaging processes, and selecting dedicated spectral bands, it provides strong sensing support for smart wearables to collect health monitoring data with higher accuracy, greater comprehensiveness, and lower power consumption.

▲NATIONSTAR 4th-Generation Intelligent Health Sensing Solution boosts product optoelectronic performance by over 30% and comprehensively enhances intelligent sensing capabilities.

—— Higher Accuracy

The solution innovatively integrates the 2008 Series (emitters), 1816 Series (emitters), and 3220 Series (receivers). Supporting both single-emitter and dual-emitter configurations, it diversifies data collection methods and improves the accuracy of vital sign measurements such as blood oxygen under varying conditions (e.g., different skin tones and motion states).

▋For emitters: Continuous optimization of the company’s proprietary packaging technology has lifted the optoelectronic performance of the 2008 and 1816 Series by more than 30%. Featuring narrow-beam light output and strong penetration, these emitters ensure more precise optical signal transmission for wearable devices.

▋For receivers: The 3220 Series delivers high visible-light sensitivity and strong anti-interference performance. It accurately captures subtle changes in optical signals, providing a reliable signal source for monitoring heart rate, blood oxygen, and other basic vital signs.

—— More Comprehensive Coverage

Thanks to its multi-device integrated design, the solution excels at fullscope physiological data collection. The 1816 Series emitters support red, infrared, and green light, while the 2008 Series emitters support red and infrared light.By expanding emitter combinations, the solution widens detection coverage and further improves the comprehensiveness of vital sign tracking.

▲Working Principle of NATIONSTAR Intelligent Health Sensing Solution

【Tech Insight】Different wavelengths of light show different sensitivities to various physiological parameters:

▋Taking heart rate monitoring as an example: When a smart wearable user’s heart beats, blood flow to the wrist increases, so more green light is absorbed. Between heartbeats, blood flow decreases, and less green light is absorbed. Thus, smart wearable devices can calculate heart rate by counting the flashing frequency of green LEDs.

▋For blood oxygen monitoring:Oxyhemoglobin and deoxyhemoglobin in blood absorb red light and infrared light at different rates.By shining light onto the skin through optical sensors, smart wearables capture reflected red and infrared light from subcutaneous blood vessels, then calculate blood oxygen levels via algorithms.

—— Lower Power Consumption

Benefiting from high luminous efficacy of emitters, high photosensitivity of receivers, and low-power design, the solution further reduces heat generation and achieves higher energy efficiency. This helps extend the battery life of wearable devices while providing stable, accurate and comprehensive monitoring data.

Forging Ahead with Strategic Layout

Unleashing New Potential in the Smart Wearable Market

According to IDC data, China’s wearable device market shipments reached 33.67 million units in Q1 2024, up 36.2% year-on-year, with smartwatches surging 54.1%.Clearly, wearables represented by smartwatches are gradually integrating into every scene of users’ daily life and work.

Seizing opportunities in the booming smart wearable market, NATIONSTAR has leveraged its core strengths and forward-looking layout to develop a series of health sensing devices:

· Receiver 4437 Series & Emitter 2516 Series

· Receiver 3220 Series & Emitter 1816 Series

These products have entered mass production and supply, with strategic partnerships established with well-known domestic brand manufacturers.
