ABSTRACT

 

Stretchable electronics have received immense interests for the applications in biocompatible, wearable, and conformable devices. In these applications, stretchable conductors with intrinsic adhesion, toughness, and mechanical compliances play a critical role to facilitate the device constructions, in place of the commonly used materials such as metallic thin films (gold (Au), silver (Ag), and copper (Cu)). Intrinsic opacity leads to limitation for transparent applications; and solution process, which is favorable for low cost, mass production, and bioresorbability is impossible because of the solubility of the conducting materials in common organic solvents. To challenge the paradigm, ionic conductors, which can be sorted into organogels and hydrogels are developed, could partially circumvent limitations in   transparency and solution processability. In this talk, I will discuss some issues related to polymer ionic conductors.
