 Ear
Digital Thermometers
It turns out that the eardrum is an extremely accurate point to
measure body temperature from because it is recessed inside the
head (just like your tongue). The problem with the eardrum is that
it is so fragile. You don't want to be touching the eardrum with
a thermometer.
This makes the detection of the eardrum's temperature a remote sensing
problem. Granted, it is not very remote -- just a centimeter or
so. But it's remote nonetheless! It turns out that the remote sensing
of an object's temperature can be done using its infrared radiation.
This technique is a very good way to detect the temperature of a
person's eardrum.
All of the objects around you are radiating infrared energy right
now. Human beings don't have any sensors that can detect subtle
differences in infrared, but our skin can detect objects radiating
lots of infrared energy. When you warm yourself by standing close
to a fire, the "warmth" is infrared energy that you are
absorbing. The idea behind the temperature sensor in the ear thermometer
is to create a device that is sensitive to very subtle changes in
infrared emission. One common sensor is the thermopile, which can
be accurate to a tenth of a degree. The thermopile sees the eardrum
and measures its infrared emissions. The emission is converted into
a temperature and displayed on an LCD.
