An　optimized　current　waveform　is　proposed　in　this　study　to　first　excite　enhanced　droplet　oscillation　and　then　utilize　it　to　enhance　the　droplet　detachment.　The　excitation　is　intentionally　generated　by　reducing　the　current　from　a　peak　level,　referred　to　as　the　exciting　peak,　to　the　base　level.　Another　peak　level,　referred　to　as　the　detaching　peak,　is　then　applied　after　a　time　interval　called　the　detaching　phase　delay　to　synchronize　the　detaching　action　with　the　beneficial　droplet　momentum　as　a　phase　match　such　that　the　droplet　detachment　is　enhanced　by　the　beneficial　momentum.　The　active　metal　transfer　control　utilizing　the　enhanced　droplet　oscillation,　referred　to　as　the　enhanced　active　metal　transfer　control,　is　further　systematically　studied　in　this　paper.　Experimental　research　shows　that　the　minimum　detaching　peak　current　in　the　enhanced　active　metal　transfer　control　is　not　only　remarkably　lower　than　the　spray　transition　current,　but　also　significantly　lower　than　that　of　the　original　active　control　process.
