Bipolar plate is one of the key components of proton exchange membrane fuel cells (PEMFC). Since the production costs of traditional graphite bipolar plates are very expensive and need a few millimeters thickness over the space, the resulting metal bipolar plate not only reduces the cost of such a bipolar plate, the thickness can also be reduced to micron range. This study aims to explore the a...

Plasticine is widely used in the analysis of metal forming processes, due to its excellent material flow ability. In this study, plasticine is used as the soft punch to fabricate array micro-channels on metal sheet in the micro sheet stamping process. This is because plasticine can produce a large material flow after being subjected to force and through the material flow, the plasticine can cau...

Regulation of tissue development and repair depends on communication between neighbouring cells. Recent advances in cell micro-contact printing and microfluidics have facilitated the in-vitro study of homotypic and heterotypic cell-cell interaction. Nonetheless, these techniques are still complicated to perform and as a result, are seldom used by biologists. We report here development of a temp...

This paper proposes a novel protein micro arrayer employing 3-in-1 chip system, instantly delivering hundreds of biosamples in parallel for disease diagnosis. The 3-in-1chip system included: micro filling chip, micro stamper array and micro bio-reaction chip, applicable to high throughput disease diagnosis and drug screening. Capillary force is applied to drive liquids flowing through all the c...

Microfabrication is actually a collection of technologies which are utilized in making microdevices. Some of them have very old origins, not connected to manufacturing, like lithography or etching. Electroplating is technique adapted to produce micrometre scale structures, as are various stamping and embossing techniques. Micro-Components are required in a range of new products such as medical ...

Abstract. Bipolar plate is one of the core components a proton exchange membrane fuel cell (PEMFC), in which microchannels with regular distribution separate and distribute gas at anode oxygen/air cathode, remove reaction products from cell. Dimensional deviations affect assembly accuracy, thereby influencing efficiency performance PEMFC. Ultra-thin stainless steel sheet most commonly used mate...

To tackle tissue vascularization, a robust 3-D micro-patterning technique was developed to create complex bioscaffolds from a synthetic biodegradable elastomer (Poly(octamethylene maleate (anhydride) citrate) by pre-patterning, solidifying, and stamping thin polymer sheets layer-by-layer to form intricate micro-structures. The bio-scaffold contains an 3-D perfusable branched network which suppo...

Direct stamping of functional materials has been developed for cost-effective and process-effective manufacturing of nano/micro patterns. However, there remain several challenging issues like the perfect removal of the residual layer and realization of high aspect ratio. We have demonstrated facile fabrication of flexible strain sensors that have microscale thick interdigitated capacitors with ...
