White Paper: High-performance photodiodes for wearable health monitoring

Wearable healthcare technology has gained widespread popularity, both in clinical settings and daily health monitoring. ElFys introduces an advancement with high-performance photodiodes (PDs) utilizing Black Silicon Induced Junction technology, aiming to enhance the accuracy and efficiency of wearable health monitors, particularly in photoplethysmography (PPG).

Optical measurements are transforming health monitoring. VTT partners with companies to develop wearable sensors.

The optical sensors used in the measurement devices contain a new kind of photodetector whose sensitivity is up to 50% higher compared to traditional technology. This new technology was developed by consortium partner ElFys.

ElFys Expands with New Mass Production Facility

ElFys has announced that it has achieved a significant milestone by delivering the first customer samples of its black silicon-based photodetectors from a mass production foundry. ElFys is already producing photodetectors at commercial scale for various market segments at its facility in Finland, but the external foundry enables ElFys to address very high-volume business segments such as consumer wearables.
