Development of IR MEMS Sensor Connected to Smart Phone via Earphone Jack

Recently, a variety of external accessory devices is applied to the smart phone. Among them, external devices which communicate through earphone jack are outstanding. The reason is that communication via earphone jack can be fixed on the smartphone easily. In this paper, The IR MEMS sensor, still under development, is presented. This IR MEMS sensor for smartphone can evaluate current temperature of the target and can be applied in many ways.
