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.

本数据集收录了聚酰亚胺基底上激光诱导石墨烯（Laser-Induced Graphene，LIG）的合成与表征实验结果，及其在传感器件开发中的相关应用数据。数据涵盖了不同激光条件下制备的LIG的分析内容，涉及10600 nm的CO₂激光、450 nm蓝光激光及355 nm紫外激光三种工艺参数，同时包含纳米结构金属氧化物半导体（Semiconductor Metal Oxides，SMOx）及其LIG-SMOx纳米复合材料的表征数据。

本研究探索的应用方向包括基于LIG的柔性电子舌（e-tongue）开发与气体传感器研制。本数据集仓库包含多种表征技术所得的实验数据：结构与形貌分析采用了拉曼光谱、X射线衍射（X-ray Diffraction，XRD）、X射线光电子能谱（X-ray Photoelectron Spectroscopy，XPS）以及扫描电子显微镜（Scanning Electron Microscopy，SEM）；电学性能表征则通过范德堡法霍尔效应测试与电化学阻抗谱（Electrochemical Impedance Spectroscopy，EIS）完成。电子舌相关数据主要基于裸电极与SMOx功能化叉指电极（Interdigitated Electrodes，IDEs）的电化学阻抗谱测试结果。

本数据集分为三个主要文件夹：
1) 激光诱导石墨烯与金属氧化物纳米颗粒表征
2) 基于LIG的柔性电子舌开发（电子舌器件数据）
3) 用于气体传感应用的LIG-SMOx纳米复合材料

每个文件夹下的子目录以对应的表征技术命名（例如“Raman”“SEM”），每个子目录均包含存放未处理原始数据的“raw”文件夹，以及用于快速预览的可视化绘图（HTML格式）所在的“visualization”文件夹。根目录下的“sample_code”文件（.csv与.xlsx格式）提供了关联各样本与其合成参数的元数据。
