Non-invasive blood glucose detection: New opportunities in the industry, printed circuit boards make their debut

Breakthroughs in non-invasive blood glucose detection technology and deep integration of circuit board technology

On February 5, 2025, Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine released a revolutionary non-invasive blood glucose detection technology-multiple micro-space offset Raman scattering (mμSORS) spectroscopy technology. This technology can complete blood glucose measurement by gently placing the palm on the detection device without pricking the finger or drawing blood, which greatly improves the compliance and quality of life of diabetic patients.

At the same time, as a global PCB&PCBA smart manufacturing platform, we ONESEINE noticed that the realization of this technology is inseparable from the support of high-precision and high-performance circuit boards. As the core component of electronic equipment, the design and manufacturing level of the circuit board directly determines the performance and reliability of the equipment.

Core principles of non-invasive blood glucose detection technology and circuit board requirements

Technical principle

mμSORS technology is based on multiple Raman spectral imaging, determines the detection depth through optical coherence tomography (OCT) technology, and uses Raman spectral signals to extract blood glucose information. This process requires high-precision optical sensors, signal processing units and data transmission modules to work together.

Key requirements for circuit boards

1. High-density interconnect (HDI) circuit boards: mμSORS devices need to integrate a large number of optical sensors and signal processing chips. HDI circuit boards can meet the needs of high-density wiring and miniaturization.

2. High-frequency circuit boards: The acquisition and processing of Raman spectroscopy signals have extremely high requirements for the stability and speed of signal transmission. High-frequency circuit boards can effectively reduce signal loss and interference.

3. Flexible circuit boards (FPC): The detection equipment needs to fit tightly with the palm. Flexible circuit boards can adapt to complex device shapes and improve user experience.

High-density interconnect (HDI) circuit boards

ONESEINE has extensive experience in the field of HDI circuit boards and can provide multi-layer, high-precision circuit board design to meet the space utilization and signal integrity requirements of mμSORS devices.

High-frequency circuit boards

Our high-frequency circuit boards use low dielectric constant materials, which can effectively support high-speed signal transmission and ensure the accuracy and real-time performance of Raman spectroscopy data.

Flexible circuit board (FPC)

ONESEINE's flexible circuit board has excellent bending performance and durability, which can adapt to the shape requirements of non-invasive blood glucose testing equipment while ensuring long-term reliability.

What opportunities will the circuit board industry usher in?

There are more than 500 million diabetics in the world. The introduction of non-invasive blood glucose testing technology will greatly promote the market demand for related equipment.

Opportunities in the circuit board industry

1. Growth of medical electronic equipment: With the popularization of non-invasive blood glucose testing technology, the demand for high-performance circuit boards in medical electronic equipment will continue to grow.

2. Promotion of technological innovation: The circuit board industry needs to continuously optimize the design process to meet the requirements of medical equipment for accuracy, reliability and miniaturization.

Conclusion

The breakthrough in non-invasive blood glucose testing technology has brought good news to diabetic patients and also provided new development opportunities for the circuit board industry. With its technical advantages in high-density interconnection, high frequency and flexible circuit boards, ONESEINE can provide high-quality circuit board solutions for medical electronic equipment and help promote and apply non-invasive blood glucose testing technology.
