However, most highly sensitive pressure sensors are optimized for low-pressure operation, and their sensitivity decreases under preloads. Here, we report a crack-interlocked ridge structure composed of two facing PDMS micro-ridge arrays and a thin Pt conductive layer. The interlocked architecture converts vertical compression into localized tensile deformation at the Pt\/elastomer interface, producing a reproducible crack-mediated resistance transition near a designed preload. The resulting sensor exhibits a maximum local sensitivity of 2582.8 kPa\u22121 within the transition window and maintains repeatable responses over 1000 loading\u2212unloading cycles. By varying the interlayer thickness, the active sensing window can be shifted across 50\u2212700 kPa, enabling preload-adapted pressure-change detection in mechanically biased configurations. As a proof of concept, the sensor detects a small additional load placed on a heavy object in a backside-mounted configuration. This crack-interlocked interface design provides a strategy for mechanically programming the pressure window of flexible resistive sensors for embedded monitoring applications.<\/jats:p>","DOI":"10.1021\/acsami.6c08499","type":"journal-article","created":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T14:19:01Z","timestamp":1784557141000},"page":"41639-41647","source":"Crossref","is-referenced-by-count":0,"title":["Crack-Interlocked Metal\/Elastomer Interfaces for Preload-Adapted Backside Pressure Sensing"],"prefix":"10.1021","volume":"18","author":[{"given":"Yan","family":"Ma","sequence":"first","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanqing","family":"Xu","sequence":"additional","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6422-9942","authenticated-orcid":true,"given":"Min","family":"Chen","sequence":"additional","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2372-3546","authenticated-orcid":true,"given":"Lan","family":"Shi","sequence":"additional","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8495-8627","authenticated-orcid":true,"given":"Limin","family":"Wu","sequence":"additional","affiliation":[{"name":"Fudan University , , ,","place":["Shanghai, China, 200433"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"issue":"5","key":"2026080518092128000_cit1","doi-asserted-by":"publisher","first-page":"652","DOI":"10.1038\/s41587-022-01528-3","article-title":"Wireless, closed-loop, smart bandage with integrated sensors and stimulators for advanced wound care and accelerated healing","volume":"41","author":"Jiang","year":"2023","journal-title":"Nat.
