Measuring Pulse Waves with Hair Thin Printed Patches
A pulse wave is a wave in which the blood flow - that originates from the heartbeat - is transmitted to the body. It is an important biosignal that indicates cardiovascular health. Analyzing the pulse wave signal can diagnose cardiac conditions including high blood pressure, arteriosclerosis and more. However, conventional pulse wave measuring devices are cumbersome as they require wearing the blood-pressure measuring cuff or stiff tong-shaped sensor and can mostly be performed at hospitals.
