They have invented a special thermometer called Thermoscan that works by infrared Ipi. This electronic device must penetrate the ear (but without touching the eardrum) and in a second gives the temperature of the eardrum, that is, the body temperature.
The device measures the infrared rays emitted by the eardrum and can be said to have the following advantages: it is simple and fast, hygienically suitable and without discomfort to children.
