Stretchable Arduinos embedded in soft robots

To achieve real-world functionality, robots must have the ability to carry out decision-making computations. However, soft robots stretch and therefore need a solution other than rigid computers. Examples of embedding computing capacity into soft robots currently include appending rigid printed circuit boards (PCBs) to the robot, integrating soft logic gates, and exploiting material responses for material-embedded computation. Although promising, these approaches introduce limitations such as rigidity, tethers, or low logic gate density. The field of stretchable electronics has sought to solve these challenges, but a complete pipeline for direct integration of single-board computers, microcontrollers, and other complex circuitry into soft robots has remained elusive. We present a generalized method to translate any complex two-layer circuit into a soft, stretchable form. This enabled the creation of stretchable single-board microcontrollers (including Arduinos) and other commercial circ..., Data was collected with MATLAB, Arduino, or Instron (materials testing) software, and processed in MATLAB. Relevant details are below. Please see the paper for more information. 
OGaIn fabrication and characterization:XRD testing was completed on a Rigaku SmartLab machine with a 2 mm window. SEM images were taken on a Hitachi CFE SU8230. EDS analysis was performed with a Bruker QUANTAX FlatQUAD (mapping at 5 kV and compositional analysis at 6 kV). Surface samples were prepared on 12.5 mm stubs on carbon tape. Cross-section samples were prepared on vertical sample holders on carbon tape, where a trace of OGaIn was frozen and then broken in half and mounted to the stub. Stretched cross sections were prepared by casting OGaIn on VHB, encapsulating it with rubber cement, and then stretching the substrate while applying it to the SEM stub. After mounting the sample, it was frozen and then broken to reveal the stretched cross-section. 
The single-trace samples were created using the dimension..., , # Stretchable Arduinos embedded in soft robots

This contains both the CSVs of data in the paper and the MATLAB files I used to process those .csv files. It also contains raw images used in some figures where data was obtained. 

General:

Each MATLAB script starts with the figure name it corresponds to (i.e., Fig 5c), and the script will ask for a .csv file upload. Choose the .csv with the corresponding figure name in the title. The script will output the data as plotted in the paper. The code is sectioned and commented on for easy understanding. NOTE: Fig 2D requires the 50 .csv files without a figure name in the file name to be in the same folder as the Fig 2D MATLAB script. These files do not have the Figure 2D indicator in the titles. Run the script with the 50 other files here in the same location, and you will get that plot.
