Abstract: Provided are an optical sensor device using surface acoustic waves and an optical sensor device package. The optical sensor device includes: a substrate including a first light sensing area and a temperature sensing area and including a piezo electric material; a first input electrode and a first output electrode which are disposed in the first light sensing area and are apart from each other with a first delay gap therebetween; a first sensing film overlapping the first delay gap and configured to cover at least some portions of the first input electrode and the first output electrode; and a second input electrode and a second output electrode which are disposed in the temperature sensing area and are apart from each other with a second delay gap therebetween. The second delay gap is exposed to air.

Abstract: A proximity sensor includes a circuit board; a light-emitting element and a light-receiving element on the circuit board; a light barrier; molding portions; and a transparent board disposed on the molding portions and configured to form an air gap with the light-receiving element. The light-receiving element includes: a substrate having a light sensing area and a temperature sensing area; a first input electrode and a first output electrode which are aligned in the light sensing area and apart from each other with a first delay gap therebetween; a sensing film covering at least some portions of the first input electrode and the first output electrode; and a second input electrode and a second output electrode which are aligned in the temperature sensing area and apart from each other with a second delay gap therebetween. The second delay gap is exposed to air.
