ABSTRACT
Circuit failure due to the open faults in the interconnect is the most often found issue in electronic systems, especially in large-area electronic systems such as display, image sensor arrays, as well as emerging fields like flexible electronics, wearable electronics. Hence to address this problem, various techniques to repair fracture interconnect in real-time have been investigated. One approach of interest for this work is the electric field-assisted self-healing (eFASH). The eFASH uses a low concentration dispersion of conductive particles in an insulating fluid that encapsulated over interconnect. As a current-carrying interconnects get fractured, which creates open fault, spontaneously an electric field appears across it. This field polarizes the conductive particles, subsequently chains them up to create a heal. This work studies the impact of dispersion concentration on the healing time, heal impedance, cross-talk when eFASH used for self-healing. Theoretical predictions have been substantiating by experimental evidence. Therefore an optimum dispersion concentration for effective self-healing is identified. Furthermore, the application of eFASH in a stretchable perspective also has been studied, which is a key advantage of this technique over others. Because the stretchability and self-healing of the open fault both got achieved with the eFASH technique. This document demonstrates the stretchable heal having a conductivity about 5* 10^5 S/m and allowing strains from 12 to 60
