| Outline of Final Research Achievements |
Recently in the electronics and drug industries, physical operations such as the transportation and separation of micro dry powders are required. However, it is impossible to operate the powders with accuracy by miniaturizing a general-purpose conveyor or blower. Therefore, we focused on a surface acoustic wave (SAW) device whose structure is simply, and investigated powder transport properties by the SAW device. As a result, it was shown that powder transport direction can be controlled by changing a drive frequency applied to an interdigital transducer (IDT) that generates the SAW, and its powder transport efficiency becomes higher as the IDT's pitch size increases. Moreover, it was also shown that the powder transport speed can be suppressed by thickness of a metal film formed on the SAW propagating area. On the base of the obtained knowledge, we succeeded in fabricating a high efficiency transport feeder for dry micro powder.
