To ask which technology in electrochemical testing is the most hair-pulling, I would say it’s EIS (Electrochemical Impedance Spectroscopy), and I think hardly anyone would disagree. There is “poetry” to prove: Measuring impedance is tough, Equivalent circuits are hard to guess; If you ask if performance improves? We’re happy if the arc shrinks! Although the … Read more
First Author: Roby Soni Corresponding Authors: Thomas S. Miller, Alexander J.E. Rettie, Affiliation: University College London, UK It is well known that Electrochemical Impedance Spectroscopy (EIS) has been widely used for battery analysis due to its simplicity and non-destructive nature. However, the data provided is generally a unified representation of all electrochemical processes within the … Read more
Click the “Battery Technology TOP+” in the upper left corner to follow! Electrochemical Impedance Spectroscopy (EIS) has attracted much attention as a powerful tool for monitoring batteries. The Equivalent Circuit Model (ECM) and the Distribution of Relaxation Times (DRT) method are widely used tools in EIS research.However, EIS faces uncertainties in practical applications within the … Read more
Introduction Recently, researchers at Purdue University in the United States developed a new type of low-cost, portable, self-powered, paper-based medical diagnostic device that can detect biomarkers and diagnose diseases. Keywords Medical Electronics、Self-Powered、Sensors Background Traditional medical diagnostic devices are often perceived as: bulky, expensive, difficult to operate, and requiring a long time to obtain diagnostic results. … Read more
