Twenty-one subjects participated in this study, which was divided into two groups: 10 subjects with flatfoot and 11 subjects with normal foot. Five force sensitive resistance sensors were used on this prototype using Arduino as the data acquisition device. Two types of trials, namely static and dynamic, were conducted to validate our system against the ink-type AI measurement as a golden standard. The results showed that in the static trial, there was a high linear correlation with the medial arch sensor configuration, while in the dynamic trial, there was a high linear correlation in the medial arch sensor configuration and sensor 5 configuration. This study showed that both static and dynamic tests using the self-developed device could effectively determine most of the flatfoot subjects and suggests that in the future, it can be applied in clinical applications because of its advantages when compared to the expensive-high tech graphic input board and conventional tools, like ink-type based measurements.<\/jats:p>","DOI":"10.3390\/s18113617","type":"journal-article","created":{"date-parts":[[2018,10,26]],"date-time":"2018-10-26T03:16:16Z","timestamp":1540523776000},"page":"3617","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["The Design and Application of Simplified Insole-Based Prototypes with Plantar Pressure Measurement for Fast Screening of Flat-Foot"],"prefix":"10.3390","volume":"18","author":[{"given":"Wei-Chun","family":"Hsu","sequence":"first","affiliation":[{"name":"Graduate Institute of Biomedical Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"},{"name":"Graduate Institute of Applied Science and Technology, National Taiwan University of Science and Technology, Taipei City 10607, Taiwan"},{"name":"Department of Biomedical Engineering, National Defense Medical Center, Taipei 11490, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8814-1275","authenticated-orcid":false,"given":"Tommy","family":"Sugiarto","sequence":"additional","affiliation":[{"name":"Graduate Institute of Biomedical Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"},{"name":"Graduate Institute of Applied Science and Technology, National Taiwan University of Science and Technology, Taipei City 10607, Taiwan"},{"name":"Division of Embedded System and SoC Technology, System Integration and Application Department, Information and Communication Research Laboratory, Industrial Technology Research Institute, Hsinchu 31057, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun-Wen","family":"Chen","sequence":"additional","affiliation":[{"name":"Graduate Institute of Biomedical Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi-Jia","family":"Lin","sequence":"additional","affiliation":[{"name":"Graduate Institute of Biomedical Engineering, National Taiwan University of Science and Technology, Taipei 10607, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"75","DOI":"10.1302\/0301-620X.35B1.75","article-title":"Naviculo-cuneiform fusion in the treatment of flat foot","volume":"35","author":"Jack","year":"1953","journal-title":"J.
