Mechanics of BMI

Abdulmalik Obaid 

Mechanical measurements of single wire insertion into the brain are important quantifications of the force and work exerted on the brain tissue during insertion, and may help identify lower-damage microelectrode designs and surgical procedures. To address the limitations of typical force transducers, we have devised a high-resolution mechanical measurement system to probe the ultra-compliant properties of the brain during penetration at much higher force and temporal resolution than previously possible. We are interested in how the design and geometry of the probes influences the mechanics of insertion, and try to find systems with as little damage as possible.
