“…The working principle of this valve is that forward flow experiences hydraulic resistance due to the looped shape of the conduit, while reverse flow experiences little to no resistance. Tesla valves have been used in various applications 31 . For example, Tesla valves are used in hydrogen fuel cell research, where the valve can be used as a decompression unit or as a micropump based on thermal cavitation.…”

Microfluidics and 3D printing offer exciting opportunities for the development of new technologies and applications in the fields of biology, chemistry, and medicine. However, the design of 3D-printed microfluidic devices remains a challenging and complex task, requiring specialized knowledge and expertise in fluid mechanics, 3D modeling, and 3D printing technology. Currently, there are very few tools helping engineers to do the labor-intensive process of designing microfluidic devices, let alone any tools that can help them design microfluidic devices for 3D printing. In this work, we introduce Flui3d, an interactive software platform for designing microfluidic devices for 3D printing. Flui3d offers a standard parameterized component library, support for multi-layer design, and the ability to design and configure microfluidic devices without the need for specialized knowledge. Flui3d incorporates a distinctive Design-for-Manufacturing (DFM) function, facilitating seamless fabrication of the designed microfluidic devices using commercial consumer-grade printers. We discuss the key features and benefits of Flui3d and demonstrate them by designing examples of microfluidic devices. We also discuss the design complexity and the potential applications of Flui3d.

“…Typically, a CO 2 laser with a wavelength of 10.6 µm are used (Mohammed et al, 2016;Persson et al, 2022). Indeed, sophisticated laser machine or reduced wavelength (e.g., femtosecond lasers) can be applied to further improve the cutting resolution, yet these methods are not suitable for low-cost microfluidics since extra costs are inevitably required (Elgohary et al, 2020;Saadat et al, 2020;Andriukaitis et al, 2022). When it comes to the materials used in laser micromachining, both hard materials such as glass and soft materials such as PMMA, cyclic olefin copolymer (COC) and even paper could be used (Islam et al, 2018;Lin et al, 2019b).…”

Effective environmental monitoring has become a worldwide concern, requiring the development of novel tools to deal with pollution risks and manage natural resources. However, a majority of current assessment methods are still costly and labor-intensive. Thanks to the rapid advancements in microfluidic technology over the past few decades, great efforts have been made to develop miniaturized tools for rapid and efficient environmental monitoring. Compared to traditional large-scale devices, microfluidic approaches provide several advantages such as low sample and energy consumption, shortened analysis time and adaptabilities to onsite applications. More importantly, it provides a low-cost solution for onsite environmental assessment leveraging the ubiquitous materials such as paper and plastics, and cost-effective fabrication methods such as inkjet printing and drawing. At present, devices that are disposable, reproducible, and capable of mass production have been developed and manufactured for a wide spectrum of applications related to environmental monitoring. This review summarizes the recent advances of low-cost microfluidics in the field of environmental monitoring. Initially, common low-cost materials and fabrication technologies are introduced, providing a perspective on the currently available low-cost microfluidic manufacturing techniques. The latest applications towards effective environmental monitoring and assessment in water quality, air quality, soil nutrients, microorganisms, and other applications are then reviewed. Finally, current challenges on materials and fabrication technologies and research opportunities are discussed to inspire future innovations.

The Tesla valve‐type drip irrigation emitter is a novel type of drip irrigation emitter that allows one‐way fluid flow and sharp water flow diversion. Orthogonal test schemes were employed to analyse the impact of structural parameters and energy dissipation mechanisms on hydraulic performance. The effect of vortex partitioning in forward and reverse flow channels on hydraulic performance was analysed. A prediction model for the emitter discharge exponent (flow index) of the structural parameters was established. The results indicated that the emitter discharge exponents of forward‐Tesla valve‐type drip irrigation emitters (FTEs) ranged from 0.47 to 0.506, and those of reverse‐Tesla valve‐type drip irrigation emitters (RTEs) ranged from 0.51 to 0.533. There was a significant disparity in the distribution of vortex zones between the FTE and RTE. The local loss coefficients of the FTE were 2.12–10.84, and those of the RTE were 1.00–3.71. The channel width D had a substantial impact on the emitter discharge exponents of the FTE and RTE, whereas the inlet length of diverter K, the length of the bevelled edge of raindrop‐type diverter B and the opening angle of raindrop‐type diverter θ had relatively smaller effects on the emitter discharge exponent. The determination coefficients of the regression model for the FTE and RTE were 0.89 and 0.84, respectively. The relative errors between the simulated and estimated values were −4.57% to 1.21%, and the experimental and estimated values were −3.72% to −1.45% in the FTE. The relative errors between the simulated and estimated values were −0.98% to 2.86%, and the experimental and estimated values were −3.72% to 1.45% in the RTE. These relative errors were all under 5%, indicating that the estimation of the emitter discharge exponent can be more accurate.
