Broadband Multi-frequency PMUT Arrays for Miniature Photoacoustic Sensing Open
Continuous and cuffless blood-pressure (BP) monitoring has attracted considerable attention in recent decades. Photoacoustic (PA) technology, which offers high vascular selectivity and encodes vessel diameter intrinsically, estimates BP by…
