The　phantom　model　of　the　leg　based　on　galvanic　coupling　IBC　(intra-body　communication)　was　established　to　simulate　the　channel　characteristics　of　human　body.　The　3D　reconstruction　of　human＇s　leg　was　carried　out　by　using　the　data　of　real　man.　It＇s　outer　contour　was　printed　by　the　3D　printer,　then　filled　it　with　the　special　solution　to　obtain　the　phantom　model.　To　verify　whether　the　phantom　model　can　be　conformity　with　reality,　the　in　vivo　experiment　was　done.　The　experimental　results　showed　that　the　outcome　of　the　phantom　experiment　was　consistent　with　that　of　the　in　vivo　experiment,　while　the　channel　length　range　from　4　cm　to　30　cm　and　the　frequency　was　at　10　kHz-500　kHz.　The　absolute　value　of　the　error　of　corresponding　data　was　less　than　7　dB.　It　turned　out　that　the　phantom　model　restructured　by　the　real　human　image　data　could　simulate　the　real　galvanic　coupling　IBC　channel　better.
