‘E-tom Smart’ Faucet is an conceptual designed faucet which uses ‘electrically’ operated piezoelectric transducer to convert high frequency electrical energy into vibratory mechanical energy at the atomizing surface, which breaks the water into tiny droplets forming atomization. The flow rate of this faucet is estimated to be 0.12 LPM,contributing to a total water saving by each faucet for about 90% and total aircraft water system savings by up to 60%. Reduction of water carriage(aircraft weight) and fuel burn will benefit airline operationally and environmentally.
