Dataset for paper entitled "A Frequency Modulation-Based Taxel Array: A Bio-Inspired Architecture for Large-Scale Artificial Skin."

Datalogs acquired during experiments related the article "A Frequency Modulation-Based Taxel Array: A Bio-Inspired Architecture for Large-Scale Artificial Skin." These datasets contains both raw data e.g. FM mixed signals generated by the electronic architecture and processed signals e.g. reconstructed demodulated signal.

The files are similarly named in pairs e.g. File1XX.txt and FileFM1XX.txt containing the processed data and mixed FM respectively. Another file per pair complements these files providing the list of main variable used (e.g. sampling rate, filters, decimation) and are named as Metadata_File1XX.txt. Two other files are included File1static8k.txt and File1static23k.txt used to generate the input/reconstruction image of the article.

These data are collected to assess the performances of the proposed architecture.

Documentation

Data collection method:

The hardware used comprises of Hall-effect sensors, FM encoding architecture, NI compact rio acquisition module and Labview processing. A magnet was used to trigger sensor response and the encoding architecture modulated the signal into FM. The NI 9775module was used to sample this analogue signal that was then modulated using realtime system built-in in the Compact RIO. FM and demodulated signal were logged (datasets).
