Abstract
Thermomechanical properties of smart polymers can be specifically tuned to address critical problems in neural interfaces. A compilation of materials and approaches is presented from each of three often overlapping research communities: shape memory polymers, hydrogels, and neural interfaces. The path toward chronically implantable devices for neural recording and stimulation relies on careful control of mechanical, chemical, electronic and geometric properties of next generation devices. These phenomena are described and put into a context of modulus changing materials, as opposed to the current focus on shape changing materials, as a paradigm that may lead to new discoveries addressing unmet clinical needs.
