Title:
PULSE WAVE SENSOR, SENSOR ARRAY AND PULSE WAVE MEASUREMENT APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/010610
Kind Code:
A1
Abstract:
Disclosed are a pulse wave sensor (6), a sensor array and a pulse wave measurement apparatus. The pulse wave sensor (6) comprises a sensor framework (1), a flexible piezoelectric sensor (2) and a static pressure sensor (3), wherein the flexible piezoelectric sensor (2) is used for sensing a pulse wave; the static pressure sensor (3) is used for measuring a static pressure applied to the pulse wave sensor (6); and the sensor framework (1) is used for fixing the flexible piezoelectric sensor (2) and the static pressure sensor (3). The pulse wave sensor (6) respectively measures a static pressure signal and a dynamic pulse wave pressure signal, and uses the flexible piezoelectric sensor (2) to measure a dynamic pressure fluctuation and uses the static pressure sensor (3) to measure a static pressure, such that a dynamic sensitivity is not influenced by a static pressure range, and a high sensitivity can be kept for a pulse wave under a static pressure with a wide range. The pulse wave sensor (6) uses the flexible sensor framework (1), such that a constituted sensor array can satisfy wrist features of different people and realize good attachment to the surface of an arm.
