Breathing clothes: artworks using the hairlytop interface

Breathing clothes are media artworks formed as an application of the hairlytop interface. The hairlytop interface is an assembly of fine, soft and deformable actuators. Each actuator is composed of a shape memory alloy (SMA) and drive circuits. Various types of sensors can be connected to the driving circuits. The actuators can then deform in reaction to surrounding stimuli, including light, sound, and human activity. The high flexibility of this configuration and its unique motion enables us to compose various interface types, such as furry decorated interfaces and new deformable textiles. In this paper, we describe in detail several types of clothes composed of this unique fabric combined with the hairlytop interface. The clothes act based on the wearer's breathing action, which acts as an indicator of the emotional state of the wearer.
