Wearable menstrual cycle sensor using inverted spectroscopy of saliva
Introducing a wearable sensor that monitors estrogen and progesterone levels through non-invasive saliva analysis. Utilizing spectral optical sensing and machine learning, this lightweight device integrates with smartphones for real-time hormonal tracking.
Overview
This innovative wearable sensor offers a non-invasive solution for monitoring menstrual cycle hormones by analyzing saliva samples. Leveraging spectral optical sensing and machine learning, this device provides real-time insights into estrogen and progesterone levels, vital for tracking the menstrual cycle phases. Compact and lightweight, akin to a smartwatch, it connects seamlessly with a smartphone app for everyday use.
Technical specifications
The sensor utilizes a combination of tailored LED lights and a broadband detector, alongside a machine learning-based calibration model. It is designed for Bluetooth Low Energy (BT-LE) connectivity, enabling easy integration with mobile devices. The development process involves building a spectral database of hormonal levels and transferring these insights into a prototype using the ScanCorder® platform. The device aims to deliver high prediction accuracy through its multispectral approach.
Technology readiness level
Currently at Technology Readiness Level 5, the sensor is in the prototype development and validation phase. Future steps include tailoring the spectral design and optimizing hardware and software components, with the goal of finalizing and deploying a functional prototype.
