Smart Wearables Could Diagnose Illness Before Doctor's Visit
Translated & summarized from NEWSru Israel by baba
Researchers from Israel's Technion and China have created a system using flexible sensors and AI to enable wearable devices to diagnose illnesses early. The technology analyzes various biological signals from the body, comparing them to an individual's personal health baseline. While promising for conditions like heart disease and diabetes, challenges like sensor stability and motion interference need to be overcome before clinical use.

Scientists from Israel's Technion and their Chinese colleagues have developed a system that uses flexible sensors and artificial intelligence to transform wearable devices into tools for early disease diagnosis. Chronic illnesses pose a major global health challenge, with current diagnostics relying on infrequent clinical measurements that often miss subtle, developing changes. This new research, published in Nano-Micro Letters, explores how wearable electronics can bridge this diagnostic gap.
The system employs four measurement methods: electrical, electrochemical, transistor, and optical. Sensors can monitor the electrical activity of the heart and brain, or detect metabolites, proteins, and hormones in bodily fluids like sweat, saliva, tears, and interstitial fluid. These flexible sensors are manufactured using printing, photolithography, and 3D technologies, then integrated with electronics, power, and wireless communication into a compact, skin-adherent system. Artificial intelligence algorithms analyze the data stream to identify significant deviations from an individual's baseline health metrics.
A key advantage highlighted by the researchers is the system's ability to integrate diverse signals and compare them against a person's unique normal range, rather than relying on generalized averages. "These achievements make accurate diagnostics possible through continuous monitoring, integration of heterogeneous data, and individual baselines," the authors stated.
Potential applications for these wearable platforms include monitoring neurological, cardiovascular, respiratory, oncological, inflammatory diseases, and diabetes. However, the researchers acknowledge that widespread clinical adoption is still distant due to challenges such as sensor instability during prolonged wear, motion artifacts, signal drift, and user variability. Despite these hurdles, the scientists are optimistic about the future of smart wearable devices for health tracking.
