# University of Chicago Develops Cardiac Patch With 99.6% Arrhythmia Detection

> Researchers at the University of Chicago have built a flexible cardiac patch that does something unusual: it runs the AI directly on the body. Instead of streaming heart data to the cloud, the patch performs inference on the device itself, detecting arrhythmias with a reported 99.6% accuracy and returning results in milliseconds. That on-device design is the whole point. For a cardiac emergency, the seconds lost sending data to a server and waiting for an answer can matter, and a patch that never depends on connectivity keeps working in an ambulance, a rural home or anywhere the signal drops. Flexible computing hardware makes it comfortable enough to actually wear. The significance is where clinical-grade monitoring is heading. Detection this accurate has traditionally lived inside hospital equipment, tethered to infrastructure. Pushing it into a thin, always-on wearable moves serious diagnostics to the point of care, and hints at a future where the early warning for a heart problem comes from a sticker on your chest rather than a visit to a clinic.
