The present specification provides a dental glass ionomer cement (GIC) composition comprising a zwitterionic material and a glass ionomer cement, and a method of preparing the same.

Glass ionomer cement compostion for dental purposes and method for preparing the same

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.

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.
