Locally Reinforced Polymer-Based Composites for Elastic Electronics
A promising approach to fabricating elastic electronic
systems
involves processing thin film circuits directly on the elastic substrate
by standard photolithography. Thin film devices are generally placed
onto stiffer islands on the substrate surface to protect devices from
excessive strain while still achieving a globally highly deformable
system. Here we report a new method to achieve island architectures
by locally reinforcing polymeric substrates at the macro- and microscale
using magnetically responsive anisotropic microparticles. We demonstrate
that the resulting particle-reinforced elastic substrates can be made
smooth enough for the patterning and successful operation of thin
film transistors with transfer characteristics comparable to state-of-the-art
device
