Appreciation towards University of Stuttgart for providing the following description:

HygroShape是世界首个真正实现自塑形概念的仿生家具。设计利用木材的天然固有特性，并采用特殊技术使家具构件以平面的形式生产并包装，在打开包装时，家具构件会自动展开成型。家具自塑成型的原理来源于木材吸湿收缩的自然现象。这一过程在无声无息中悄然发生，无需人的参与，亦无需使用任何工具或安装说明，它就这样在眨眼之间平稳地展开。

HygroShape is a first of its kind concept for truly self-shaping furniture. Using the natural, intrinsic properties of wood, furniture pieces are produced in physically programmed flatpack configurations, materially programmed to shape themselves when unpacked. This self-shaping emerges from the hygroscopic shrinkage that naturally occurs in wood materials. It happens effortlessly, in silence, without human interaction, tools, or assembly instructions, unfurling smoothly, as quickly as overnight.

一旦展开形成，家具中的机械构件会牢牢地锁在一起，创造出稳定性，并通过微小且和谐的变形迎合人体工学，创造出最佳舒适性。该项目代表了设计和制造过程的转变，实现了对材料的控制，通过实践发掘可持续材料的潜力。随之而来的是一种全新的材料设计语言，将材料的天然品质和特征转化为形式和功能的综合表达。

Once shaped, the parts lock mechanically creating stability, while retaining an active ergonomic function through small harmonious movements. The project represents a shift in design and manufacturing processes implementing material programming to harness the unique potentials of sustainable materials and practices. With this comes a new material design language embracing the qualities and characteristics of the natural as an integrative expression of form and function.

由本项目衍生出来的hylo tech公司，将继续探索自塑技术在材料内部和结构应用方面的潜力。

The spin-off company hylo tech continues the exploration of this technology’s potential for a range of interior and structural applications.
