Technology
VitaSense is based upon three core components that elevate it to never-before-seen heights, planting itself as the first ever wholly non-invasive continuous health monitoring device.
Photoplethysmography
At the heart of VitaSense's functionality lies photoplethysmography, a non-invasive method for measuring blood volume changes through light. The armband emits light through the skin using a light source and then detects the changes in light with a photodetector. This process captures optical signals arising from glucose interactions within the blood, enabling continuous and real-time monitoring without the need for invasive procedures.
Germanium Selenide (GeSe)
VitaSense employs GeSe, a black crystalline powder, as a semiconductor in its glucose monitoring armband. GeSe's unique properties, including an atomic-level thickness, tunable electronic structures, and high flexibility, make it an ideal sensing material for glucose detection. Its well-matched bandgap with the solar spectrum and high optical absorption are crucial features.
Semiconductor-Based Sensors
VitaSense incorporates semiconductor-based sensors to enhance the precision and sensitivity of glucose measurements. These sensors operate using diodes and temperature-sensitive voltage, facilitating the easy detection of changes and contributing to the accuracy of glucose level tracking. The integration of semiconductor technology ensures the reliability of the armband's glucose-monitoring capabilities.
