Episode 6: Embedded sensor pinpoints stress inside batteries

MRS Bulletin Materials News Podcast · Apr 19, 2022 · 4m

In this podcast episode, MRS Bulletin’s Laura Leay interviews PhD candidate Laura Albero Blanquer and her professor, Jean-Marie Tarascon, from the Collège de France in Paris about their study on what occurs inside the cells of both liquid and solid-state batteries. They embedded the optical Fiber Bragg grating sensor that reflects monochromatic light, revealing a shift in the peak wavelength when there is a change in temperature, pressure, or stress. The sensors were calibrated so that only changes in stress could be detected. This research will lead to new opportunities to look at commercial…
