| Abstract: |
| To investigate the feasibility and channel propagation characterization of Ultra
wideband(UWB) wireless communication for biomedical implantable electronic de
vices, a highresolution 3D electromagnetic model of human body based
on computed tomography(CT) and magnetic resonance imaging(MRI) segmented images
of living human males is presented, the frequency range is 1～10.8 GHz,
and the electromagnetic characters for 85 different kind of human tissues or org
ans are considered. The model is embedded in 3D electromagnetic(EM) simulator
based on finite integration technique(FIT) for electromagnetic computation to i
nvestigate the path loss and specific absorption rate(SAR) in body. Experiment
result shows that the model can well characterize the electromagnetic characters
of real human body, the signal loss is aggravating with the higher frequency
and deeper implant depth; the path loss for 3.5 GHz is 75 dB under
an implant depth of 160 mm and, with a reference power of 27 dBm, the S
AR in body for 3.5 GHz is under the safety region. These results demonstrate t
he feasibility and security of applying 3.5 GHz on UWB for wireless communic
ation in biomedical implantable devices. |
