Senspectra is a computationally augmented physical modeling toolkit designed for sensing and visualisation of structural strain. The system functions as a distributed sensor network consisting of nodes, embedded with computational capabilities and a full spectrum LED, which communicate to neighbor nodes to determine a network topology through a system of flexible joints. Each joint, while serving as a data and power bus between nodes, also integrates an omnidirectional bend sensing mechanism, which uses a simple optical occlusion technique to sense and communicate mechanical strain between neighboring nodes. Using Senspectra, a user incrementally assembles and refines a physical 3D model of discrete elements with a real-time visualisation of structural strain.
