A foldable modular wall system includes a track, one or more stationary wall modules, and one or more foldable wall modules. The foldable wall modules are pivotally and slidably connected to the track such that the foldable wall modules can be selectively moved between a closed confirmation and an open configuration. The foldable modular wall system can also include power hinge jumpers through which electrical wires can nm to power electronic components embedded in or disposed on the foldable wall modules.
