Welcome to the Pulsenics Knowledge Centre
This resource serves as a comprehensive guide to understanding all facets of Electrochemical Impedance Spectroscopy (EIS), from the underlying science to real-world applications and measurement best practices.Whether you're new to impedance analysis or an experienced electrochemist looking to deepen your expertise, this Knowledge Centre is designed to meet you where you are. We've organized content to take you from foundational principles, how and why impedance measurements work, through to advanced topics like equivalent circuit modelling, data interpretation, and troubleshooting common artefacts.EIS is one of the most powerful and information-rich techniques in electrochemistry, capable of probing processes across many orders of magnitude in frequency. But that power comes with complexity. Our goal here is to make that complexity approachable: clear explanations, practical guidance, and worked examples grounded in the kinds of problems our users actually encounter.Inside, you'll find:
- Science & Theory — The physics and mathematics of impedance, from basic circuit analogies to the Kramers–Kronig relations
- Instrumentation & Setup — How to configure your system for reliable, low-noise measurements
- Applications — How EIS can be used across a range of fields, including batteries, fuel cells, and electrolysers
- Data Analysis — Fitting strategies, model selection, and common pitfalls
- Best Practices — Practical tips for getting the most out of every measurement
This is a living resource, updated as the science evolves and as we learn from our community. If you have questions or topics you'd like to see covered, we'd love to hear from you.
