The　distribution　and　changes　in　plantar　pressure　are　closely　related　to　human　health,　and　can　be　used　to　assess　the　presence　of　foot　diseases.　Accurate　assessment　of　plantar　pressure　distribution　plays　a　preventive　and　diagnostic　role　in　foot　diseases.　In　order　to　achieve　the　function　of　assessing　foot　conditions　through　plantar　pressure,　the　characteristics　and　differences　in　plantar　pressure　variation　among　different　individuals　were　studied.　Flexible　and　thin-film　pressure　sensors　with　array　distribution　were　used　to　collect　plantar　data　from　both　healthy　individuals　and　diabetic　patients.　MATLAB　was　used　to　generate　pressure　distribution　maps　of　average　peak　pressure,　with　different　colors　representing　the　intensity　of　pressure　in　different　regions.　Python　was　used　to　generate　line　graphs　and　pie　charts.　The　line　graph　intuitively　shows　the　pressure　distribution　in　different　regions　of　the　foot,　while　the　pie　chart　presents　the　proportion　of　each　region＇s　pressure　in　the　total　pressure.　Analysis　revealed　that　approximately　50%　of　the　body　weight　is　borne　by　the　heel　during　the　weight-bearing　process　of　standing,　with　higher　pressure　on　the　medial　side　of　the　heel　compared　to　the　lateral　side.　The　other　parts　are　borne　by　the　first　to　fifth　metatarsal　bones.　Significant　differences　were　observed　in　peak　plantar　pressure　between　diabetic　patients　and　healthy　individuals.　The　experimental　results　demonstrate　that　this　study　can　collect　and　analyze　pressure　at　different　parts　of　the　foot,　and　identify　any　abnormal　conditions.　The　study　reveals　the　patterns　of　peak　pressure　distribution　in　the　foot,　thereby　serving　the　prevention　and　monitoring　of　foot　diseases,　including　diabetic　foot.　©　2023　IEEE.
