These mechanical transmission systems and insulin reservoirs occupy more than one\u2010third of pumps\u2019 volume, significantly limiting miniaturization and making pumps cumbersome for daily use. Herein, a compact, magnetically actuated insulin pump is developed that is less than one\u2010quarter the size of piston\u2010based pumps. Instead of bulky mechanical components, the pump uses a magnetic soft actuator to directly compress the insulin chamber, controlled by a precisely tuned electromagnetic field. This innovative design eliminates the need for large transmission systems, enabling a notably smaller form factor. In addition, the fine\u2010tunable magnetic actuation enables a 0.01\u2009\u03bcL delivery resolution, significantly surpassing the 0.25\u2009\u03bcL resolution of piston\u2010based pumps. This high\u2010resolution mechanism facilitates further miniaturization by allowing the use of high\u2010concentration insulins, thereby reducing the reservoir size. By varying the magnetic field's waveform, amplitude, and duration, the pump's performance can be further enhanced. The reported magnetic insulin pump exhibits superior repeatability and accuracy across single\u2010pulse, basal, and bolus modes compared to commercial insulin pumps. This miniaturized, high\u2010resolution magnetic insulin pump is anticipated to substantially benefit people with diabetes by improving portability, precision, and cost efficiency.<\/jats:p>","DOI":"10.1002\/aisy.202500459","type":"journal-article","created":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T12:26:02Z","timestamp":1755260762000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Mini\u2010Patch Magnetic Insulin Pump for Enhanced Delivery Resolution and Accuracy"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3260-8956","authenticated-orcid":false,"given":"Qiji","family":"Ze","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering Stanford University  Stanford CA 94305 USA"}]},{"given":"Shuhao","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stanford University  Stanford CA 94305 USA"}]},{"given":"Yilong","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stanford University  Stanford CA 94305 USA"}]},{"given":"Jize","family":"Dai","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stanford University  Stanford CA 94305 USA"}]},{"given":"Rayhan A.","family":"Lal","sequence":"additional","affiliation":[{"name":"Departments of Medicine &amp; Pediatrics Divisions of Endocrinology Stanford University  Stanford CA 94305 USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9292-5267","authenticated-orcid":false,"given":"Ruike Renee","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Stanford University  Stanford CA 94305 USA"}]}],"member":"311","published-online":{"date-parts":[[2025,8,15]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781119697473"},{"key":"e_1_2_9_3_1","author":"Magliano D.
