Thin film transistor circuits on flexible substrates is the big promise for next generation human-machine interface systems. However, a major bottleneck is the reliability of the interconnect that is prone to open circuit faults due to mechanical, electrical and environmental stress. Here we demonstrate self-healing interconnects in thin film transistor circuits on flexible substrates resulting in the restoration of > 99% of the pre-fault current. The active material for self-healing is a dispersion of conductive particles in an insulating fluid that is contained over the interconnect. Healing is triggered by the electric field that appears in the open gap during the occurrence of the fault. We discuss the engineering of the active material, demonstrate and analyze self-healing circuits and discuss methods to package and integrate the self-healing feature with the process flow. This work sets a new benchmark for reliable inkjet-printed thin film transistor circuits on flexible substrates. |
