System and method for surface acoustic wave treatment of skin

摘要

Methods and devices for treating skin include a skin-contacting portion, an actuator and a processor, wherein activation of the actuator causes surface acoustic waves of Rayleigh, “pseudo” Rayleigh types to be produced on the skin around the actuator. In a location which is under the actuator, the actuator produces tension and repulsion of skin particles. These surface acoustic waves can be used to provide treatment to the skin, including wound healing, non-adhesion of bandages, reduced infection, reduced pain and cosmetic enhancements. The skin-contacting portion may be a patch or bandage, a glove, a hand-held device, or any other suitable configuration. The actuator is incorporated into the skin-contacting portion.

主权项

1. A method for treating human skin, the method comprising:
positioning a piezo bender actuator on the skin, wherein said actuator is comprised of piezoelectric material glued to a metallic plate; electrically connecting said actuator to a processor; activating said actuator via said processor, thereby enabling said actuator to vibrate in natural bending vibration modes; said vibrating actuator producing surface acoustic waves in the form of running waves on the skin around the actuator and wherein said producing causes skin particles to move elliptically; and wherein the distance between two maximal amplitudes of said bending vibration modes are proportional to a half wave length of said surface acoustic waves produced on the skin; and controlling parameters of said activating so as to achieve particular treatment effects on the skin by said produced surface acoustic waves.
