Insertion of Flexible Neural Probes Using Rigid Stiffeners Attached with Biodissolvable Adhesive Sarah H. Felix1, Kedar G. Shah1, Vanessa M. Tolosa1, Heeral J. Sheth1, Angela C. Tooker1, Terri L. Delima1, Shantanu P. Jadhav2, Loren M. Frank2, Satinderpall S. Pannu1 1Materials Engineering Division, Lawrence Livermore National Laboratory, 2UCSF Center for Integrative Neuroscience and the Department of Physiology, University of California, San Francisco Insertion of flexible neural microelectrode probes is enabled by attaching probes to rigid stiffeners with polyethylene glycol (PEG). A unique assembly process ensures uniform and repeatable attachment. After insertion into tissue, the PEG dissolves and the stiffener is extracted. An in vitro test method evaluates the technique in agarose gel.
Planar and Three-Dimensional Printing of Conductive Inks Bok Yeop Ahn1, Steven B. Walker1, Scott C. Slimmer1, Analisa Russo1, Ashley Gupta1, Steve Kranz1, Eric B. Duoss1,2, Thomas F.
