Safe exposure limits should be maintained, and protective housing and padding are generally needed; however, these impose compromises on the power-transfer-system design. This paper analyses these trade-offs and proposes a design route to achieving high power transfer in the presence of field restrictions and separations for padding or housing materials. An IPT system using a Class D coil-driver and switched-mode power-conditioning is designed to provide regulated d.c. and energy storage. Compliance with ICNIRP 1998 guidelines is demonstrated, at a power level that is sufficient to power typical on-body medical sensing devices.||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2015 IEEE||Keywords:||On-body sensing;Inductive power;Wireless power transfer;Healthcare||DOI:||10.1109/WPT.2015.7140171||Language:||en||Status of Item:||Peer reviewed||Is part of:||Wireless Power Transfer Conference (WPTC)||Conference Details:||IEEE Wireless Power Transfer Conference, Boulder, Colorado, USA,13-15 May, 2015|
