Blood pressure (BP), a crucial health biomarker, is essential for detecting early indications of cardiovascular disease in routine monitoring and clinical surveillance inpatients. However, conventional cuff-based BP measurements are limited providing continuous comfort monitoring. Here, we present an optical pulse sensing patch monitoring, which integrates three units Gallium Nitride (GaN) optopairs with micronanostructured polydimethylsiloxane films to capture waves. Multipoint signals transformed into other indicators through machine learning. The transfer learning method developed calibrate the model few training sets, simplifying practical implementation. holds great potential long-term, precise enhancing diagnosis, management diseases.
