Specific absorption eate (SAR) value.

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these changes. The method is based on the creation of a primary magnetic field that will produce eddy currents in the trunk, currents will produce a secondary magnetic field that has to be detected around the trunk. The objective is to know the sensitivity of such a method to the geometric and impedance changes in the trunk considering the safety issues.
