Based on concept of ”rotating coordinates”, this study used small wireless camera to build a rotary platform and an observation device that can capture still shoots of the changes of the microfluidic chips under centrifugal force synchronously-”Flash 3”. Compared with Flash 2, which was developed based on the concept of ”Stroboscope” by our team, Flash 3 experimental system has advantages of simple design, economical cost, portability and all-time observation. This study proposed concepts and theories concerning centrifugal ”non-radial” microfluidic drive based on experimental verification, and developed the new ”plane driving” biochips to provide diversity and applicability, as well as a new direction of development and design.
