Pulse Transit Time PPG Dataset

We provide an open access, high resolution and time synchronised dataset from multiple sensors worn at different body locations including Photoplethysmogram (PPG), Inertial, Pressure and ECG. The recordings are from 22 healthy subjects performing 3 physical activities. This dataset contains 66 waveform records from multi-site and multi-wavelength PPGs, sensors' attachment pressures, sensors' temperatures, inertial data from accelerometer and gyroscope, along with annotated ECG data for a total of 19 channels. Additionally, systolic and diastolic blood pressures, as well as blood oxygenation saturation levels (SpO2) numerics are provided.本数据集为一款开放获取、高分辨率且时间同步的多模态数据集，其数据来自佩戴于人体不同部位的多款传感器，包含光电容积描记图（Photoplethysmogram, PPG）、惯性传感器、压力传感器及心电图（Electrocardiogram, ECG）信号。该数据集的录制对象为22名健康受试者，受试者完成了3种体育活动。本数据集包含66条波形记录，涵盖多部位、多波长光电容积描记图数据、传感器附着压力数据、传感器温度数据、加速度计与陀螺仪采集的惯性数据，以及经标注的心电图数据，共计19个通道。此外，数据集还提供了收缩压、舒张压以及血氧饱和度（SpO2）的数值型数据。
