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.
