Abstract
This paper is to present the design consideration of the adjustable flexible auxetic structure which is used in the soft wearable suit with the multi-layer materials. In order to design a macro-auxetic structure with the elastic flexibilities of the soft wearable suit, it is important to make the auxetic unit cell with the elastic adjustability. We make the tension experiments of several specimens, for verifying the mechanical structural characteristics of auxetic unit cell with flexure hinge mechanism. Through this approach, the valid geometric parameters of macro-auxetic structure used in the soft wearable suit can be designated.
