Description: An intelligent structural cell system for modular buildings and infrastructure is disclosed. The system comprises a plurality of structurally load-bearing cells, each cell having a structural body, one or more interfaces for connection with neighboring cells, and one or more sensing, processing, communication, energy, material-delivery, repair, or actuation components. The cells form a distributed structural network in which condition information associated with load, strain, deformation, cracking, temperature, energy condition, environmental exposure, or other structural parameters can be collected and shared among neighboring cells or a supervisory control system.
