HEART BEAT SENSORS, HEART BEAT SENSOR-EMBEDDED NEAR-INFRARED ORGANIC IMAGE SENSORS AND SMART PHONES COMPRISING THE SAME, AS WELL AS WEARABLE HEART BEAT SENSORS, AND ANGIOGRAPHIC DEVICES

摘要

PROBLEM TO BE SOLVED: To provide a heart beat sensor which uses a photoelectric conversion device having wavelength selectivity so that a low output LED may be used to prevent skin damage and to reduce power consumption.;SOLUTION: The heart beat sensor includes a light emitting unit configured to emit white light, and a sensor unit configured to detect transmitted or reflected light after the light emitting unit irradiates a blood vessel with the white light. The sensor unit includes a near-infrared organic photoelectric conversion device and a red photoelectric conversion device.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
