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.本数据集为开放获取的高分辨率时间同步多传感器数据集，传感器佩戴于不同身体部位，涵盖光电容积描记图（Photoplethysmogram, PPG）、惯性传感器、压力传感器与心电图（Electrocardiogram, ECG）采集的信号。该数据集的记录来自22名完成3种体力活动的健康受试者，包含66条多位点多波长PPG波形记录、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ECG数据，总计19个通道。此外，数据集还提供收缩压、舒张压以及血氧饱和度（SpO2）的数值信息。
