Tactile sensor hardware based on programmable SoC

This reported work focuses on the implementation of data acquisition electronics for a piezoresistive tactile sensor. It commonly involves the use of quite bulky electronics not very suitable to be housed in artificial hands, for instance. A very compact implementation because it is not based on a conventional microcontroller but on a programmable system-on-chip (SoC) is presented. This device implements analogue blocks that are not present in standard microcontrollers, so they do not have to be added as extra integrated circuits on the PCB, and a compact implementation based on a single chip plus a few electronic components is obtained.
