Researchers at the University of the Tartu are developing a wearable that resembles a smartwatch and uses spectrometry to detect plastic particles in the human body without drawing blood.

The project aims to provide a noninvasive view into how plastics may travel through the body and potentially affect health.

By using advanced spectrometry the device can scan tissue fluids and bodily excretions in real time offering ongoing monitoring rather than a single snapshot.

The wearable is designed for daily use and to integrate with existing digital health systems so that users and doctors can receive alerts about detected materials.

The researchers emphasize safety and privacy ensuring that the spectroscopy data remains encrypted and accessible only to authorized medical professionals.

If successful this technology could transform how scientists study the body through its interaction with environmental plastics and how clinicians assess exposure risks.

The development is being conducted with clinical partners and will undergo rigorous testing before any clinical deployment or consumer release.
