Physical and FEM Simulation of Microprobe Insertion into Rat Brain

A. E. Olamat, N. Nkemasong, B. M. Pohl, U. G. Hofmann


In order to investigate theimplantation of microprobes into brain tissue, wedeveloped a finite-element and a physical modelto replace real biological tissue for mechanicaltesting. Penetrating forces of a tungsten indenterinto a layered structure was investigated withdifferent indentation speeds. Numerical andphysical model are in good correspondence toeach other and reproduce measured brainelasticity (15kPa) and dimpling effects followedby rupturing of the top layer well. We suggestfor future mechanical evaluation of brain probesto first utilize model structures before sacrificinganimals.
