Title:
DROPLET REMOVAL DEVICE AND DROPLET REMOVAL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/045000
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a droplet removal device and a droplet removal method that enable removal of droplets attached to the surface of an object by vibrating and moving droplets. The droplet removal device according to the present invention is provided with: a dielectric layer having one principal surface that makes contact with droplets and the other principal surface; and one electrode and the other electrode disposed at a distance from each other on the other principal surface of the dielectric layer. The one principal surface of the dielectric layer has water repellency exhibiting a contact angle of at least 90 degrees to droplets. An alternating-current voltage is applied between the one electrode and the other electrode to vibrate and move droplets that are in contact with a portion of the one principal surface of the dielectric layer between an area located above the one electrode and an area located above the other electrode.
