摘要： A composite film includes a substrate that is not responsive to relative humidity, and also one or more layers of hygromorphic material. The hygromorphic material expands in response to an increase in relative humidity and contracts in response to a decrease in relative humidity. In some cases, the composite film is bi-layer or tri-layer. The composite films are fabricated such that they undergo a desired bending pattern in response to changes in relative humidity. In some cases, these bending patterns are combinations of two bending primitives: a smooth curve and a sharply angled curve. These two primitives are combined to create a variety of shape transformations including 1D linear transformation, 2D surface expansion and contraction, 2.5D texture change and 3D folding. Any type of hygromorphic material may be employed, including living gram positive and gram negative bacterial cells, yeast cells, plant cells, mammalian cells, cell debris, or hydrogel.

摘要翻译：复合膜包括对相对湿度不响应的基底以及一层或多层的湿型材料。响应于相对湿度的增加并且响应于相对湿度的降低，变形材料膨胀。在一些情况下，复合膜是双层或三层。制造复合膜，使得它们响应于相对湿度的变化而经历期望的弯曲图案。在某些情况下，这些弯曲图案是两个弯曲图元的组合：平滑曲线和锐角曲线。这两个图元被组合以产生各种形状转换，包括1D线性变换，2D表面膨胀和收缩，2.5D纹理变化和3D折叠。可以使用任何类型的hygromorphic材料，包括活的革兰氏阳性和革兰氏阴性细菌细胞，酵母细胞，植物细胞，哺乳动物细胞，细胞碎片或水凝胶。

摘要： In some implementations, bending or other shape changes of a device are actuated by inflating or deflating a bladder in the device. Then, once the desired new shape is achieved by this actuation, another bladder in the device is layer-jammed, to make the device rigid in the new shape. In some cases, sheets in the layer-jamming bladder are coated with abrasive particles. In some cases, layer jamming bladders are interwoven to form a woven device. The rigidity of the woven device can be anisotropically controlled. Layer jamming some, but not all, of the bladders in the woven device causes the woven device to have a rigidity that varies by direction. In some cases, a layer-jamming bladder includes a solid layer with a crease in it. As a result, the bladder can easily bend at the crease.
摘要翻译：在一些实施方案中，装置的弯曲或其它形状变化通过使装置中的膀胱膨胀或放气来致动。然后，一旦通过该致动实现了期望的新形状，则装置中的另一个囊被层压，以使装置刚性成新的形状。在某些情况下，层状阻塞气囊中的片材涂有磨料颗粒。在某些情况下，层间干扰的气囊交织在一起形成编织装置。编织装置的刚性可以各向异性地控制。编织装置中的一些但不是全部的囊的层堵塞导致织造装置具有随方向变化的刚性。在某些情况下，层状阻塞气囊包括其中具有折痕的固体层。结果，膀胱容易在折痕处弯曲。

摘要： In exemplary implementations of this invention, a shape controller controls the shape of a bladder as the bladder inflates. The shape controller includes a first set of regions and a second set of regions. The second set of regions is more flexible than the first set of regions. The shape controller is embedded within, or adjacent to, a wall of the bladder. When the bladder is inflated, the overall shape of the bladder bends in areas adjacent to the more flexible regions of the shape controller. For example, the shape controller may comprise paper and the more flexible regions may comprise creases in the paper. Or, for example, the more flexible regions may comprise notches or indentations. In some implementations of this invention, a multi-state shape display changes shape as it inflates, with additional bumps forming as pressure in the display increases.

摘要翻译：在本发明的示例性实施方案中，形状控制器在膀胱膨胀时控制膀胱的形状。形状控制器包括第一组区域和第二组区域。第二组区域比第一组区域更灵活。形状控制器嵌入在膀胱壁内或邻近膀胱壁。当膀胱膨胀时，膀胱的整体形状在与形状控制器的更柔性区域相邻的区域中弯曲。例如，形状控制器可以包括纸，并且更灵活的区域可以包括纸中的折痕。或者，例如，更灵活的区域可以包括缺口或凹痕。在本发明的一些实施方案中，多状态形状显示器随着其膨胀而改变形状，随着在显示器中的压力增加形成的附加凸起增加。
