Purpose The measurement of the transfer function is a good tool to evaluate the radiofrequency heating of complex conductive wires, such as pacemaker leads. The aim is to describe precisely the design of a transfer function bench and compare the meas

Introduction MRI is nowadays an indispensable technique with its excellent resolution achieved without ionizing radiations. Active implantable medical devices exist (such as pacemakers) which are MRI-compatible and do not show any hazardous local hea

International audience; Correct modelling of damping is essentiel to capture the dynamic behaviour of a NEMS device. Our interest is squeeze-film damping which models the behaviour of a fluid in small gaps between a fixed surface and a structure movi
