Computational Assessment of Neural Probe and Brain Tissue Interface under Transient Motion [PDF]

Biosensors, 2016
The functional longevity of a neural probe is dependent upon its ability to minimize injury risk during the insertion and recording period in vivo, which could be related to motion-related strain between the probe and surrounding tissue.
