The dataset contains raw and processed data files. Raw files are in the .zip file format and include - Microscope images for estimating in-plane displacement of tuning actuators (including a USAF resolution target reference image for size calibration). - Vibrometer voltage measurements for frequency response curves with and without on-chip tuning Processed files are in .csv file format and include - Frequency response data with and without tuning - Tuning response data - In-plane lateral displacement data - Optical angle vs voltage data - Mirror surface curvature data - Device temperature profile data - Device frequency variation data Detailed description and creation of the figures present in the associated manuscript are in the .ipynb (Jupyter notebook) file.
