Assessing the Safety Margin for Micromotion‐Induced Strain at Electrode–Tissue Interface: A Finite Element Analysis via COMSOL (Adv. Mater. Interfaces 9/2025)

Neural Device Development In article 2401001, Danesh Ashouri Vajari, Thomas Stieglitz, and co-workers investigate the impact of brain movement on the biocompatibility of neural probes by simulating strain profiles at the electrode-tissue interface under various displacements. Their findings challenge the 5% strain damage threshold, highlighting size-dependent micromotion models and the potential for integrating immunohistological data to assess probe design in the early stages of neural device development.
