First author Young Scientist Pariya Nazari presents the realization of a highly sensitive and highly compliant microfiber strain sensor for high-resolution and real-time Li-ion battery thickness monitoring in a new Cluster publication published in Advanced Materials. The good dynamic strain sensing properties, lightweight, miniature form factor and high durability suggest that this economic and simple approach offers promising pathways for in-situ lithium-ion battery thickness monitoring applications. The publication is the result of a close collaboration between Heidelberg University and KIT. Also involved were PIs Jasmin Aghassi-Hagmann, Gerardo Hernandez Sosa and Uli Lemmer.
