Electrical Impedance Tomography #

Electrical Impedance Tomography (EIT) is an imaging technique that reconstructs the internal conductivity distribution of an object by applying electrical signals through an array of electrodes and measuring the resulting responses. EIT has applications in industrial sensing, process monitoring, medical imaging, and non-destructive testing.

As part of a client-focused proof-of-concept project, Alberta 2514640 Inc. supervised the development of an open-source EIT platform completed by a University of Calgary capstone team during the 2023–2024 academic year.

The project included the design of custom electronics, data acquisition hardware, and software capable of collecting impedance measurements from multiple electrodes and reconstructing a representation of the measured environment. The resulting system was successfully demonstrated in a water test tank, where it was able to detect and localize submerged objects based on changes in electrical conductivity.

The complete hardware and software design has been released as open source and is available on GitHub:

While developed as a proof of concept, the project demonstrates the potential of low-cost EIT systems for sensing and imaging applications. The work also serves as an example of Alberta 2514640 Inc.’s involvement in applied research, hardware development, and technical project supervision.

We are interested in future opportunities involving scientific instrumentation, sensing systems, and custom electronics development.
