EMF Characteristic Inside the Infant Incubator Compartment

Infant incubator is one of MEEs (Medical electrical equipment) that is largely used to preserve preterm and sick babies from postnatal stressors. However, their motors produce high electromagnetic fields (EMFs) which could affect the incubator as well as its occupants. In this paper, it has been done the EMF measurement to study and to quantify the level of EMF by mapping the magnetic field distribution inside the compartment of infant incubator. Measurement method was conducted on three layers from the mattress by magnetic near field probe and Spectrum Analyzers. The result showed that by p<0.005, the EMF is not significantly different from layer 1, layer 2, and layer 3. The averages values of the EMF are 0.53
$\mu \mathrm{T}, 0.98\mu \mathrm{T}$
, and 0.97
$\mu \mathrm{T}$
, at first, second and third layer on every stage of heater level. This EMF is far below the standard level for magnetic field ERLs for exposure of limbs, and head and torso at 0 Hz to 5MHz by the IEEE and ICNRP.
