Microchannel (microtechnology)

Microchannel in microtechnology is a channel with a hydraulic diameter below 1 mm, usually 1–99 μm.

[2] They are more efficient than their 'macro' counterparts, because of a high surface-area to volume ratio yet pose a multitude of challenges due to their small size.

[4] polymethyl methacrylate (PMMA) is used as a solution to a wide range of microfluidic devices due to its low cost and easier fabricating methods.

[7] The concept of the microchannel was proposed for the first time by researchers Tuckerman and Pease of Stanford Electronics Laboratories in 1981.

[8] They suggested an effective method for designing microchannels in the laminar and fully developed flow.
