RingConn

RingConn reports a large-scale bilateral PPG study in npj Digital Medicine showing synchronized dual-hand monitoring improves heart-rate measurement and signals reliability across 12 AI models. Analyzed 97,559 samples from 1,810 participants, reducing MAE to 2.59 bpm.

RingConn highlights Ninenovo's collaboration with SJTU and Mianyang Central Hospital on a large bilateral ring-PPG study published in npj Digital Medicine, analyzing ~100,000 PPG segments from ~1,800 participants and showing bilateral inputs improve heart-rate accuracy and reliability.

RingConn's bilateral ring-based PPG study shows heart-rate error down from 10.65 bpm to 2.59 bpm across 1,810 participants; systolic MAE drops from 13.81 to 12.36 mmHg and diastolic from 9.27 to 8.21 mmHg; results validated across 12 AI models.
