Light and ultrasonic transducer device for skin therapy

A light and ultrasonic transducer device having a layered structure for delivering light and ultrasound to a skin surface, comprising:

• a plurality of flexible conductive layers including a transparent conductive layer and at least two other conductive layers;
• a flexible light source layer comprising one of an organic light emitting diode or a plurality of printed light emitting diodes, wherein the flexible light source layer is positioned between the transparent conductive layer and one of the other conductive layers, wherein the flexible light source layer emits light when driven by a first power source connected to the transparent conductive layer and the one of the other conductive layers;
• a flexible ultrasonic transducer layer comprising a piezoelectric coating, wherein the flexible ultrasonic transducer layer is positioned between two of the other conductive layers, wherein the flexible ultrasonic transducer layer emits ultrasound when driven by a second power source connected to the two of the other conductive layers;
• and
• a flexible substrate for supporting the flexible light source layer, the flexible ultrasonic transducer layer, and the flexible conductive layers
• wherein the light and ultrasound emitted from the device cause transdermal transport of a therapeutic or cosmetic composition through the skin surface.
