我们提出了一种快速原型技术，扩大弹性阀门的能力，从薄材料，如塑料薄膜和胶带制成的设备。从概念到功能设备的完全制造所需的时间在几个小时之内。该技术的一个关键特征是器件很薄（厚度通常小于0.5 mm），这允许制造具有许多层的器件。该特征还允许将装置折叠成具有全功能瓣膜的3D结构。我们说明了这一概念与制造的每边25毫米的立方体，其壁包含微流体通道和阀门。通过C.当刺激通过立方体的壁传递到内表面时，线虫在立方体的封闭体积内迁移。
We present a rapid prototyping technique that expands elastomeric valving capabilities to devices made from thin materials such as plastic films and tapes. The time required from conception to full fabrication of functional devices is within a few hours. A key characteristic of this technology is that devices are thin (typically less than 0.5 mm in thickness), which allows for the fabrication of devices with many layers. This feature also permits folding of devices into 3D structures having fully functional valves. We illustrate this concept with the fabrication of a 25 mm-per-side cube whose walls contain microfluidic channels and valves. Control of liquid delivery through the faces of the cube is demonstrated with a chemotaxis experiment of C. elegans migrating within the enclosed volume of the cube as stimuli are delivered through the walls of the cube to the interior faces.
