In this paper, a novel self-healable and stretchable microfluidics system for next generation wearable lab-on-a-chip is presented. An imine-based precursor with various metal sources (Co(II), Fe(II), and Zn(II)) is used for the development of an intrinsically autonomous self-healing microfluidic device. Microfluidics fabrication is performed on the self-healing substrate layer using a mold transfer method. The mechanical properties of the resulting layer are evaluated using tensile strain pull testing. Microfluidic characteristics including fluid flow, wettability, leak, and fluorescence compatibility are investigated to understand its performance in classical microfluidic applications. The new microfluidic devices are also characterized using scanning-electron microscopy to evaluate …

The development of stretchable electronic devices that are soft and conformable has relied heavily on a single material – polydimethylsiloxane – as the elastomeric substrate. Although polydimethylsiloxane has a number of advantageous characteristics, its high gas permeability is detrimental to stretchable devices that use materials sensitive to oxygen and water vapor, such as organic semiconductors and oxidizable metals. Failing to protect these materials from atmosphere-induced decomposition leads to premature device failure; therefore, it is imperative to develop elastomers with gas barrier properties that enable stretchable electronics with practical lifetimes. Here, we reinvent butyl rubber – a material with an intrinsically …
