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
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【課題】波長選択性がある光電変換素子を適用して低出力のＬＥＤを使用可能にして皮膚損傷を防止し、電力消費量も減少させることができる心拍センサを提供する。【解決手段】本発明による心拍センサは、白色光を発光する発光部と、前記発光部から血管に前記白色光が照射された後、透過した光又は反射した光を検出する、近赤外線有機光電変換素子及び赤色光電変換素子を含むセンサ部と、を有する。【選択図】 図１
