Artificial 'Wrist' Enables Design of Wearable Blood Pressure Monitors

摘要

Unfortunately, blood pressure (BP) measurements currently require the use of a cuff that temporarily stops blood flow. A wearable BP "watch" using today's technology would squeeze the wrist every few minutes, making it impractical to use. A better method might gauge subtle pressure changes at the surface of the skin above one of the main wrist arteries — the radial artery — without regularly cutting off circulation. But before this new technology can be devel- top of a metal plate, which substitutes for bone. A pliable tube runs through the silicone to mimic an artery, through which fluid flows via a mechanical heart pump.
