New research indicates that loose clothing can track body movement with 40% more accuracy and 80% less data than traditional tight wearables. This challenges the belief that loose sensors produce noisy data. The study suggests a shift towards 'smart clothing' that feels natural while effectively monitoring health. Researchers at King’s College London found that loose fabrics can detect subtle movements, aiding in monitoring conditions like Parkinson's. Current wearables have limitations in clinical metrics, despite being useful for exercise tracking.
