For powder transport in micro total analysis systems, we proposed and fabricated a novel surface acoustic wave (SAW) actuator with a Bragg reflector. By using the SAW actuator, we carried out a powder transport experiment. As a result, it was found that the powder was transported along the upstream of the SAWs, and the powder transport direction was changed at a certain point by the reflection of the SAWs. The zigzag transport path indicates possibility of a more flexible design of a micro powder transport system.
