A micro liquid rotor operated by surface acoustic waves (SAWs) was proposed and fabricated. The liquid rotor has two interdigital transducers (IDTs) that generate SAWs, in order to increase efficiency of rotating the liquid. The IDTs were fabricated

Surface acoustic wave (SAW) devices, because of their very simple structures, can be used as component parts for micro total analysis systems. We focused on a liquid flow actuator operated by SAWs and investigated highly efficient interdigital transd
