A system for delivering light and/or ultrasound across a skin surface is provided. The system includes a device having a layered structure comprising one or both of a light source and an ultrasonic transducer. The light source comprises a flexible light emitter layer electrically coupled to a first conductive layer and a second conductive layer, wherein at least one of the first and second conductive layers is transparent. The ultrasonic transducer comprises a flexible ultrasound emitter layer electrically coupled to a third conductive layer and a fourth conductive layer. The system also includes one or more sensors in contact with the skin surface and a controller electrically coupled to the device and the sensor. The controller is operable to receive sensor data from the sensor and dynamically control the device in response to the received sensor data.
