Document Type and Number:
WIPO Patent Application WO/2019/225042
Kind Code:
A1
Abstract:
Provided is an oscillation device with which it is possible to reliably move water droplets, without relying on differences in surface tension at different positions. This oscillation device 1 comprises: an oscillating element 2 having a oscillating body 3 having a translucent body 4 (translucent body portion) and a piezoelectric oscillator 5A (oscillator) which oscillates the oscillating body 3; a transparent electrode layer 15 provided on the translucent body 4 of the oscillating body 3; a dielectric layer 16 provided on the transparent electrode layer 15; and a voltage application circuit which is electrically connected to the transparent electrode layer 15 and which applies a voltage to the transparent electrode layer 15.
