UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed a user-friendly analytical instrument that measures electrochemical impedance at rates many times faster than currently available devices and with comparable accuracy.
Electrochemical cells are ubiquitously used in hybrid vehicles, biosensors, and electronics. Electrochemical impedance spectroscopy (EIS) is a powerful analysis technique used to characterize electrochemical cells. The current commercial instruments suffer from long measurement time, high unit cost, difficulties for custom measurement process, and poor data management system for large-scale datasets.
UCLA researchers have developed an EIS instrument that is superior to existing counterparts in price, run time and user-friendliness. The instrument is on average 5-10 times faster than the current in-lab gold standard instrument and is projected to be several times less expensive to manufacture. The instrument allows users to customize their methods to allow for a variety of experiments and provides real time data visualization on the internet.
The fourth version of the instrument has been developed and has been shown to be superior to its commercial counterparts. Further optimization of the device software and hardware are underway.
