Soft neural interfaces: Bending stiffness

This lecture by the instructor covers the topic of soft neural interfaces, focusing on the bending stiffness of penetrating electrodes. The lecture discusses the bending stiffness of axons and penetrating probes, presenting ideal geometrical models and elastic modulus ranges. Various aspects such as cylinder beams, rectangular cross-sections, and tri-layer stacks are explored in relation to bending stiffness. The lecture also delves into the miniaturization of penetrating electrodes and the operation models of different structures, providing insights into the design and properties of soft neural interfaces.
