Scope and Objectives
Self healing circuits. In many systems the interconnects of circuits experiences stress due to mechanical forces, thermal expansion, ESD events, electromigration, environmental degradation etc. In such cases the interconnect may experience open circuit faults. The project aims to develop an idea where the open faults are immediately detected and healed.
Deliverables
1.) Self healing interconnects 2.) to achieve heals with low resistance 3.) stretchable heals

Results and outcome till date
Details found in the manuscript (freely dowloadable pdf): Self Healing Interconnects with a Near Plastically Stretchable Heal A Kumar, V Parab, A Handu, L Ding, S Sambandan arXiv preprint arXiv:1808.04270 2018 (accepted, Physical Review Applied)
Societal benefit and impact anticipated
Reliable electronics for space, consumer applications. Systems like cell phone displays can be self healed. This implies less consumer wastes (environmental benefit long term). Technologies such as wearable and flexible electronics become more reliable.
Next steps
Solving the problem of packaging to translate this mechanism to a (i) printed circuit board (ii) flexible electronic system.
