Recently, TRUMPF Photonic Components announced that it would cooperate with RSP Systems of Denmark to provide vertical cavity surface emitting laser (VCSEL) technology, and both sides are expected to bring the first clinically relevant wearable non-invasive glucose sensor.
Berthold Schmidt, CEO of Tongkuai Photonics, said: "With our understanding of the photonics mechanism, we will soon be able to provide diabetes patients with easier and lower cost painless blood glucose measurement solutions. This cooperation once again demonstrates the innovative potential of VCSEL technology."
In the past 10 years, RSP Systems has developed an accurate, factory-calibrated and clinically validated glucose monitor that can provide accurate glucose readings without calibration by touching the skin.
Although RSP Systems has now developed portable, optical and sensor-based devices to measure glucose levels, these devices are not as portable and easy to operate as paperbacks.
Anders Weber, CEO of RSP Systems, said, "We will cooperate with Tongkuai Photonic Components to build a wrist wear device, which aims to cover all uses of hundreds of millions of people from insulin treatment to diabetes risk."
Tongkuai cooperates with RSP Systems to make blood glucose monitoring easier for patients with diabetes. The solution aims to pair TRUMPF VCSEL with RSP Systems' optical sensor-based monitoring equipment and integrate it into wrist devices. The partnership is based on the existing touch glucose monitoring (TGM) technology of RSP Systems.
Previously, many enterprises around the world have explored and practiced the concept of wrist glucose monitoring supported by photonics. In July 2021, UK-based Rockley Photonics released its "clinic on the wrist" solution, which is based on a microchip and can provide continuous and non-invasive monitoring of core biomarkers. Rockley Photonics reported that the range of biomarkers detected and monitored using infrared spectroscopy technology is larger than the existing wearable consumer electronic devices that use green LED to monitor heart rate. The company said in 2021 that its sensor module generates a large number of discrete laser outputs from a single silicon chip covering a wide range of optical bands. In addition to heart rate and blood glucose trends, Rockley said that the solution can also enable wearable devices to monitor core body temperature, blood pressure, body moisture, etc.
According to the data of the International diabetes Federation, there are about 540 million adults worldwide with diabetes, half of whom have not yet been diagnosed. The number of people affected is expected to increase to 643 million by 2030 and 783 million by 2045. This trend has also led to the rapid development of the sensor wearable market. In recent years, other wearable systems have further considered the use of Raman spectroscopy, and many enterprises have explored dielectric spectroscopy and used quantum cascade lasers (QCLs) in spectroscopy. Bertold Schmidt said that VCSEL has contributed to the realization of wrist glucose sensor, which can be monitored at any time.
