Nice to see you here!
This document will help you to know how to make your own Bio-Skin tactile sensor. If you still don't know what is Bio-Skin, please check our project homepage for more detail: https://williamalexanda.github.io/Bio-Skin/
Hardware of Bio-Skin will be open sourced under the Creative Commons Attribution-NonCommercial 4.0 International License, which means it's open for personal NonCommercial usage only.
Hardware parts include all molds, materials list and code for Esp32. Without software in PC, you can still get the sensor raw data by following this tutorial: https://youtu.be/GShOp8S6hr8
If you want the software which includes super-resolution or GUI or have any other questions, please send a email(haoran.guo@okstate.edu) to get more information.
