Tactile Sensing Module with a Dense Arrangement of Sensors


This module features a high-density arrangement of 36 MEMS barometric pressure sensors in a compact 50x65 mm form factor, with potential applications in robotics and other fields. The goal is to explore the sampling frequency, potential hysteresis issues, and other influencing factors. The module utilizes 36 MEMS barometric pressure sensors. In addition to this hardware, a separate controller module (GitHub) has been developed to interface with the module and sample data.

At the moment, only part of the tactile sensing hardware is populated and tested, as I’ve been occupied with other projects. I plan to resume work and publish the complete version along with test results when I have more time.

The schematics, evaluation results, and additional details will be shared once testing and evaluation are complete. I’m documenting the progress so far, but since this is a personal project, I need to prioritize other commitments for the time being.

Possible Applications:

Possible applications of this tactile sensing module include robotics, touchpads, gaming interfaces, and other fields that can benefit from tactile sensing.
