Hsinchu, Taiwan – April 14, 2025:
TSLC Corporation, a wholly owned subsidiary of SemiLEDs Corporation, and SCIVAX Corporation have revealed a pioneering breakthrough in sensor technology with the launch of the world’s smallest PhotoPlethysmoGraphy (PPG) sensor head. This cutting-edge technology, designed to measure pulse waves from blood vessels, is set to transform the wearable health monitoring market. The first samples of the PPG sensor head will be available for evaluation starting in April 2025.
The development stems from a strategic partnership between TSLC and SCIVAX, which combined TSLC’s advanced packaging technology with SCIVAX’s nano-imprinting lens technology. This collaboration led to the creation of the world’s smallest light source device, Amtelus, which serves as the foundation for the new PPG sensor head. This breakthrough has enabled the creation of a compact sensor head significantly smaller than conventional designs, making it ideal for integration into health-focused wearables such as smartwatches and fitness trackers.
The new sensor head is incredibly small, with a mounting area of just 1 square millimeter—only 1/10th the size of traditional devices. Additionally, the thickness of the sensor head is roughly half that of conventional models. This dramatic reduction in size allows the sensor to be used in previously inaccessible narrow spaces, opening new possibilities for health monitoring in both personal and professional applications.
The compactness of the sensor head also supports its integration into arrays of multiple sensors, improving the precision of blood flow measurements and enabling more accurate monitoring of vital health metrics. This makes the sensor head suitable not only for use in smartwatches but also in home healthcare, beauty devices, and even nursing applications. Furthermore, the sensor’s resin packaging, which integrates both the light source and optical sensor, offers a significant cost advantage compared to traditional PPG sensors.
Looking ahead, TSLC and SCIVAX aim to expand the application of this technology to the next-generation life sciences sector, with a focus on vital sensors for healthcare monitoring and diagnostics. The small size, cost efficiency, and enhanced functionality of the PPG sensor head provide an excellent platform for the development of smarter, more accurate health devices.
TSLC, based in Hsinchu Science Park, Taiwan, is a leading developer of optoelectronic systems and precision packaging solutions. SCIVAX, a company specializing in nano-imprinting technology, offers advanced solutions for high-precision molding and optical applications. Together, these two companies are setting the stage for the next wave of innovations in wearable health technology and beyond.
