Flexible Sensors Based on Laser Induced Graphene

This dataset contains experimental results from the synthesis and characterization of Laser-Induced Graphene (LIG) on polyimide substrates and its application in the development of sensing devices. The data covers the analysis of LIG produced under different laser conditions (CO2 at 10600 nm, blue at 450 nm, and UV at 355 nm), as well as the characterization of nanostructured semiconductor metal oxides (SMOx) and their LIG-SMOx nanocomposites.

The explored applications include the development of a flexible electronic tongue (e-tongue) based on LIG and gas sensors. The repository includes data from multiple characterization techniques. Structural and morphological analysis was performed by Raman Spectroscopy, X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), and Scanning Electron Microscopy (SEM). Electrical properties were investigated through Hall Effect measurements (Van der Pauw method) and Electrochemical Impedance Spectroscopy (EIS). The e-tongue data is primarily based on EIS measurements on both bare and SMOx-functionalized interdigitated electrodes (IDEs).

The data is organized into three main folders:
1) Characterization of Laser Induced Graphene and SMOx nanoparticles
2) E-tongue based on LIG Development (e-tongue device data)
3) LIG-SMOx nanocomposites for gas sensing aaplications

Within each folder, subdirectories are named after the characterization technique (e.g., 'Raman', 'SEM'). Each contains a 'raw' folder with unprocessed data and a 'visualization' folder with plots (HTML) for quick preview. A root file named 'sample_code' (.csv and .xlsx) provides the metadata linking each sample to its synthesis parameters.
