Frequency Tunable Electromagnetic Vibration Energy Harvester Utilizing Piecewise Linear Nonlinearity Dataset

This is the data gathered during the experiments referenced in the manuscript. All files are .mat and native to Matlab. The variable "time' is the time array gathered during operation corresponding to the 'data' array of the same length. 'data' contains 2-3 columns depending on the file. The first column is always the base displacement voltage output, the second is the mass displacement voltage output, and if a third column is included then this is the measured voltage at the load applied to the harvester.本数据集为手稿所引用的实验采集所得数据。所有文件均采用.mat格式，为Matlab原生数据文件。变量"time"为实验运行期间采集的时间数组，其长度与对应的数据（data）数组完全一致。"data"字段根据文件不同包含2至3列数据：第一列始终为基座位移电压输出，第二列为质量块位移电压输出；若包含第三列，则该列为施加于该能量收集器（harvester）的负载端实测电压。
