We describe a low-cost setup developed to carry out SAR measurements on a human phantom. The development comprises: a human phantom manufactured using a modified workflow from the mannequin industry, liquid preparations using recipes found in the literature, a system for the transmission and reception of RF signals, a system for tracking the position of a field probe during the scanning, which is carried out manually, and a system for the integration and post-processing of the measured data. Preliminary validation results demonstrate good performance for all the blocks described. Detailed results from an underway measurement campaign with these blocks will be presented during the conference.
