Vivisection is an experiment in spatial formation within architecture and design based on the idea of a robotic membrane. Vivisection is the making of a live section, a sensing skin that acts and reacts on its inhabitation. As a spatial experiment it is the thinking of how a techtonic surface can embed a capacity for sensing and actuation. The fabric, a weave of silk and steel, is conductive thereby allowing us to pass electronic signals through it. By using antenna based sensor chips the fabric itself becomes a sensor, which feels the presence of its audience. The sensors inform a network of distributed micro-computers, that in turn control the fans, inflating and deflating internal bladders in the structure.
