In this study, we combine a resistive sensor based on a cracked PEDOT: PSS structure with a 70\u2009MHz double-loop gold antenna, enabling high-precision and continuous measurement of intraocular pressure (IOP). By comprehensively optimizing the sensor design, device structure, and wireless detection system, we achieved a sensitivity of 47.31 \u03a9\/mmHg\u2014approximately 15 times higher than conventional approach, corresponding to a resistance change 183 times larger. Both in vitro wireless IOP measurements of a porcine eye and in vivo wireless IOP measurements of rabbit eyes altered by microbead injection, using a commercial tonometer and a fabricated sensor lens, showed a strong correlation with R\u00b2 values of 93% and 97%, respectively. These findings highlight the platform\u2019s potential for long-term, non-invasive IOP monitoring, thus making a significant contribution to early diagnosis and treatment of glaucoma.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Journal Title \/\u63b2\u8f09\u30b8\u30e3\u30fc\u30ca\u30eb\u540d npj Flexible Electronics Publication Year and Month \/\u63b2\u8f09\u5e74\u6708 January, 2026 Paper Title \/\u8ad6 [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[],"tags":[218,217],"class_list":["post-83306","post","type-post","status-publish","format-standard","hentry","tag-impact-en","tag-impact"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/83306","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/comments?post=83306"}],"version-history":[{"count":1,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/83306\/revisions"}],"predecessor-version":[{"id":83307,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/posts\/83306\/revisions\/83307"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/media?parent=83306"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/categories?post=83306"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/research\/wp-json\/wp\/v2\/tags?post=83306"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
