DESCRIPTION:Prof Christopher J Bettinger\, Carnegie Mellon University\, US
 A.\nImplantable neural interfaces underpin many technologies that rely on 
 recording and stimulating neuronal activity from organs in the central and
  peripheral nervous systems. Reliable and stable chronic recording from ex
 citable tissues using implantable multielectrode arrays has been elusive t
 o date due\, in part\, to host tissue interactions that contribute to devi
 ce failure. Local tissue damage and device failure is worsened by the mech
 anical mismatch between materials used to fabricated rigid silicon-based m
 icrofabricated multielectrode arrays (EMEA ~ 100 GPa) and tissues in the n
 ervous system (EPNS ~ 10 kPa). Hydrogel-based electronics could reduce the
  mechanical mismatch across the tissue-device interface and enhance perfor
 mance. Here we present materials and companion fabrication strategies to c
 reate ultracompliant electronic devices for use in peripheral nerve interf
 aces. Integrated strategies for polymer synthesis\, processing\, and micro
 fabrication are described. Details regarding the in vitro and in vivo perf
 ormance of these devices will also be presented.\n\nBio:  Christopher Bet
 tinger is a Professor at Carnegie Mellon University in the Departments of 
 Materials Science and Engineering and Biomedical Engineering. He directs t
 he laboratory for Biomaterials-based Microsystems and Electronics at CMU\,
  which designs materials and interfaces to integrate medical devices with 
 the human body. Chris has published over 80 articles and has been issued o
 ver 10 patents. Chris has received honors including the National Academy o
 f Sciences Award for Initiatives in Research\, the MIT Tech Review TR35 To
 p Young Innovator under 35\, and the DARPA Young Investigator Award.  Pro
 f. Bettinger is also a co-inventor on several patents and Co-Founder and C
 TO of Ancure\, an early stage medical device company. Prof. Bettinger rece
 ived an S.B. in Chemical Engineering\, an M.Eng. in Biomedical Engineering
 \, and a Ph.D. in Materials Science and Engineering as a Charles Stark Dra
 per Fellow\, all from the Massachusetts Institute of Technology.  He comp
 leted his post-doctoral fellowship at Stanford University in the Departmen
 t of Chemical Engineering as an NIH Ruth Kirschstein Fellow.\n
