Electronic device and estimation system

Abstract

An electronic device includes a sensor unit configured to acquire a pulse wave of a subject's carotid artery and a controller configured to estimate a condition of the subject's carotid artery based on the pulse wave acquired by the sensor unit.

1 . An electronic device, comprising:
 a sensing plate including at least one sensor configured to acquire a pulse wave of a subject's carotid artery;   an elastic member to press the sensing plate such that the sensing plate presses skin over the subject's carotid artery, and that the sensing plate is displaced in response to a movement of the subject's carotid artery;   a housing;   a processor configured to estimate a condition of the subject's carotid artery based on the pulse wave acquired by the at least one sensor,   wherein the at least one sensor comprises an angular velocity sensor, and   the second end of the sensing plate is displaceable in the direction substantially vertical to a plane of a back side of the electronic device.   
     
     
         2 . An estimation system, comprising:
 an electronic device that includes:   a sensing plate including at least one sensor configured to acquire a pulse wave of a subject's carotid artery;   an elastic member to press the sensing plate such that the sensing plate presses skin over the subject's carotid artery, and that the sensing plate is displaced in response to a movement of the subject's carotid artery;   a housing;   an estimation devise that includes a processor configured to estimate a condition of the subject's carotid artery based on the pulse wave acquired by the at least one sensor,   wherein the at least one sensor comprises an angular velocity sensor, and   the second end of the sensing plate is displaceable in the direction substantially vertical to a plane of a back side of the electronic device.
