- TSLC, a subsidiary of SemiLEDs (LEDS, Financial), and SCIVAX have developed the world's smallest PPG sensor head.
- The sensor features a 1 square millimeter mounting area and reduced thickness, allowing installation in narrow spaces.
- Sample distribution for evaluation will begin in April 2025, targeting applications in beauty, healthcare, and nursing sectors.
TSLC Corporation, a wholly-owned subsidiary of SemiLEDs Corporation (LEDS), in collaboration with SCIVAX, has announced the development of the smallest PPG (PhotoPlethysmoGraphy) sensor head in the world. This groundbreaking device boasts a mounting area of approximately 1 square millimeter, a mere 1/10th of the size of conventional sensors, and its thickness has been halved compared to traditional models. The sensor is designed with an integrated resin package that combines both the light source and optical sensor, providing significant cost advantages.
This miniaturization achievement enables the PPG sensor head to be installed in narrow, previously inaccessible spaces, and supports multiple deployments, offering enhanced precision in vital health measurements. The small size and advanced functionality open new application possibilities in sectors such as beauty, home healthcare, and nursing.
Evaluation samples of this innovative sensor will start distribution in April 2025. The development of the PPG sensor head leverages TSLC's advanced packaging technology alongside SCIVAX's nano-imprinted lens technology, a collaboration that previously led to the Amtelus® light source device.
With the potential for multiple sensor array deployments, this new sensor could revolutionize health monitoring technology by increasing accuracy through redundancy and improved signal processing, addressing key limitations in current wearable device designs.
