Modular EIT: Open-Source Freedom and Scalable Electrical Impedance Tomography

Electrical Impedance Tomography (EIT) research often demands flexibility and the ability to adapt hardware to unique experimental configurations. Yet many EIT systems on the market are expensive, closed-source, and difficult to customize, which can slow down innovation and limit what researchers are able to test. A recent publication introduces a different approach: a modular open-source platform for EIT applications that brings together customization, scalability, and high-precision measurements.

The Advantage of a Modular Open-Source EIT Platform

The platform described in the study combines flexible, open-source switching electronics with a high-precision impedance measurement engine. This architecture allows researchers to build EIT systems that are both scalable and tailored to their experimental needs, without being locked into proprietary hardware.

Because the system is modular, each subsystem—from electrode switching logic to data acquisition—can be configured independently. This is especially powerful for:

• Custom configurations:Adapting to unique geometries, multi-layer phantoms, or integration with custom software stacks.

• Cost reduction:Open-source design and commodity components make advanced EIT setups more accessible for academic labs and rapid prototyping.

• Component validation:New switching matrices, electrode arrays, or reconstruction algorithms can be validated against a reliable impedance reference.

Sciospec EIT16: The Precision Measurement Core

For any open-source platform to succeed in demanding imaging applications, the impedance measurement core must be robust and precise. In this work, theSciospec EIT16serves as thecentral impedance engine, providing the accuracy and stability needed for high-quality EIT data.

The EIT16 is designed for multi-channel impedance tomography and general multi-port impedance measurements, with true parallel acquisition across 16 channels. Key capabilities include:

• Synchronous 16-channel acquisition:Consistent impedance input for reliable tomographic reconstruction.

• Wide frequency support:Operation across relevant bandwidths for both biological and industrial applications.

• Protocol compatibility:Straightforward integration into open-source workflows via standard APIs and interfaces.

Scaling Up: From 16 to 256 Channels and Beyond

One of the biggest strengths of the Sciospec EIT architecture is its scalability. The same platform that powers the EIT16 also underlies higher-channel-count systems such as EIT32, EIT64, EIT128, and EIT256.

This means a research team can start with an EIT16 for feasibility studies, phantoms, or education, and later scale up to higher resolution or denser electrode arrays without redesigning the signal-processing stack or replacing the core measurement engine. Channel expansion remains compatible with existing software, accessories, and reconstruction workflows, protecting both time and budget.
