摘要:
Provided is a surface acoustic wave atomization device (1) which can generate, with a simple and compact constitution, a mist provided with new positive effect by making gas or ions to dissolve in a supplied liquid while atomizing. This device (1) comprises a substrate (3) which is made of a piezoelectric material, and on which a pattern electrode (2) for generating a surface acoustic wave (W) is formed. When high-frequency voltage is impressed to the pattern electrode (2), this device (1) generates the surface acoustic wave (W). When a liquid (L) is supplied to an area in the surface (S) where the surface acoustic wave (W) propagates, this device 1 makes the liquid (L) fly as micro-particles (M) and atomizes the liquid (L) by energy of the surface acoustic wave (W). Additionally, this device (1) comprises a pair of electrodes (4) which is arranged facing the surface of the substrate (3) and electrolyzes the supplied liquid (L). The surface acoustic wave atomization device (1) holds the supplied liquid (L) between the electrodes (4) and the surface (S) of the substrate (3) by using its surface tension. By impressing voltage between the pair of electrodes (4) in atomizing, this device (1) can make gas or ions generated by electrolysis dissolve into the liquid (L) in in-situ of atomization to generate a mist provided with new positive effect.
