Microfluidicshas been the key component for many applications, including biomedical devices,chemical processors, micro actuators, and even wearable devices. Thistechnology relies on soft lithography fabrication which requires cleanroomfacilities. Although popular, this method is expensive and labor-intensive.Furthermore, current conventional microfluidic chips preclude reconfiguration,making reiterations in design very time-consuming and costly. To address theseintrinsic drawbacks of micro fabrication, we present an alternative solutionfor the rapid prototyping of microfluidic elements such as micro tubes, valves,and pumps. In addition, we demonstrate how micro tubes with channels of variouslengths and cross-sections can be attached modularly into 2D and 3Dmicrofluidic systems for functional applications. We introduce a facile methodof fabricating elastomeric micro tubes as the basic building blocks formicrofluidic devices. These micro tubes are transparent, biocompatible, highlydeformable, and customizable to various sizes and cross-sectional geometries.By configuring the micro tubes into deterministic geometry, we enable rapid,low-cost formation of microfluidic assemblies without compromising theirprecision and functionality. We demonstrate configurable 2D and 3D microfluidicsystems for applications in different domains. These include micro particlesorting, micro droplet generation, biocatalyticmicromotor, triboelectricsensor, and even wearable sensing. Our approach, termed soft tubular microfluidics,provides a simple, cheaper, and faster solution for users lacking proficiencyand access to cleanroom facilities to design and rapidly construct microfluidicdevices for their various applications and needs.
