Sergi P. N., Biomimicry of Echinocactus grusonii Spines as a Source of Inspiration for Design Principles and Implantation Strategies of Self-Inserting Intraneural Interfaces, Biomimetics, 2025, 10(11):773, doi: 10.3390/biomimetics10110773
A theoretical analysis of buckling in spine-inspired structures. The author compares geometry, local reinforcement of the shaft and tip support conditions, proposing design principles for intraneural interfaces.
