Document Type and Number:
Japanese Patent JP2012019926
Kind Code:
A
Abstract:
To provide a plethysmogram sensor that accurately measures a pulse wave.
The plethysmogram sensor has a plurality of light emission parts (LED1-LED8) provided at different positions, at least one light reception part (PD) for detecting the intensities of the light emitted from the light emission parts through the living body of a person to be measured for each of the light emission parts, and an operational processor for acquiring the pulse wave of the person to be measured on the basis of the measured value output from the light reception part.
