Electronic systems used in space technology applications experience harsh environments, resulting in several failures among which open circuit faults are one. In this work, we investigate self-healing circuits to automatically respond to and repair open circuit failures in electronic systems. The active material is a dispersion of metallic particles in an insulating fluid, and the mechanism of healing is triggered by the electric field appearing in the fault. Specifically, this work discusses the physics of self-healing and investigates the compatibility of the mechanism to high vibration (1-16�g) as well as thermovacuum conditions (5���10-5Torr and �40-125�°C). In conclusion, we demonstrate that the electric field assisted self-healing mechanism is feasible for space technology applications. © 2021 Author(s).
