Modular Pneumatic Faade System (MPFS), attempts tojuxtapose key characteristics of biological design

(modularity, robustness, homeostasis, and adaptive)

with smart technologies (material, sensor, actuation,and control) in order to create a kinetic faade systemthat respond and interact with its environment in real-time.

Similar to how an independent cell coordinates witheach other to undergo certain tasks in multicellularsystems in nature, the MPFS is consisted of autonomous

modules that collectively achieve assigned functions.Each MPFS module is integrated with its own sensor,actuation, and control components which contribute tothe robustness of the system as well as allow it to adaptto external stimulus. As an aggregated system, MPFSshas potentials to initiate emergent behaviors at theglobal level due to the chain reaction betweenindividual modules at the local level. Inspired by thehydro skeletons and muscular hydrostats in nature (e.g.elephant trunk, starfish, octopus arm, etc.), the

A flex sensor and a photocell sensor weretested to see how effectively Firefly can bridgebetween the preliminary designed geometryand the micro-controller. The geometry wasbuilt using Grasshopper and Rhino, as aparametric/ generative model. The sensor datathat flows into the Firefly components areconverted using ReMap component andSmooth component in order to manipulate theparameters of the geometry.
