Abstract:
Porous silicon has become the gold standard when it comes to improving biocompatibility and bioactivity. For this reason, it has become a primary candidate in neural electrodes research and development. Consequently, the purpose of this work was to investigate the mechanical strength of porous silicon neural electrodes. Thus, a finite element model representing the proposed electrode was generated. Mechanical simulation was done on porous and non-porous electrodes using COMSOL® Multiphysics. Results showed that porosity decreased the mechanical strength of the neural electrode without risking the mechanical requirements for neural applications.
