Dataset for the Identification of an Energy Harvester

This dataset contains the measurements of the procedure to fully characterise a novel vibration energy harvester (presented in https://doi.org/10.1016/j.apenergy.2023.120715) operating in the ultra-low-frequency range. The details of the experimental setup and fully characterization procedure can be found in: https://doi.org/10.3390/s24123813

The experimental measurements include not only the input (acceleration)–output (energy) response but also the (internal) dynamic behaviour of the system, making use of a synchronised image processing and signal acquisition system.

The result of the processed video (angular positions of the masses) and calculation of their two time derivatives by means of the Tikhonov regularization have also been included. Additionally, the calculation of the power generated in the windings has also been included.

In "Videos" folder are the recorded videos at 240fps.
In "Measurements" folder data form each experiment can be found in different files. First column is time, second and third columns are accelerometer measurements, and the rest of the columns are the different voltages measured at each coil.
In "Post-processed data" are the estimated angular positions (2,3,4 columns), velocities (4,5,6 columns) and accelerations (7,8,9 columns) obtained form the post-processed videos. The last column is the estimated power harvested by the device.
The name of the file name is in line with the experiment.

本数据集包含用于全面表征一款新型振动能量收集器（vibration energy harvester）的实验测量数据，该设备已在https://doi.org/10.1016/j.apenergy.2023.120715中被提出，其工作频段为超低频范围。实验装置的详细信息与完整表征流程可参见：https://doi.org/10.3390/s24123813。

本次实验测量不仅涵盖输入（加速度）-输出（能量）响应，还借助同步图像处理与信号采集系统，获取了该系统的（内部）动态行为数据。

经处理的视频结果（质量块的角位置），以及通过蒂霍诺夫正则化（Tikhonov regularization）计算得到的其两个时间导数也已纳入本数据集。此外，数据集还包含线圈中产生的功率计算结果。

在"Videos"文件夹中，存放了帧率为240fps的录制视频。
在"Measurements"文件夹中，各次实验的相关数据以多个独立文件存储。其中第一列为时间数据，第二、第三列为加速度计（accelerometer）测量值，其余列则为各线圈测得的不同电压数据。
在"Post-processed data"文件夹中，存放了经后处理视频得到的估算角位置（第2、3、4列）、速度（第4、5、6列）与加速度（第7、8、9列）数据。最后一列为该设备收集的估算功率。
文件名与对应实验一一匹配。
