Self\u2010healing capability and four\u2010dimensional (4D) printability are becoming increasingly important for these materials to facilitate their recovery from damage and endow them with stimuli\u2013response properties. However, it remains challenging to design a single material that combines these four strengths. Here, a dually crosslinked hydrogel is developed by combining a covalently crosslinked acrylic acid (AAC) network and Fe\n                    <jats:sup>3+<\/jats:sup>\n                    ions through dynamic and reversible ionically crosslinked coordination. The remarkable electrical sensitivity (a gauge factor of 3.93 under a strain of 1500%), superior stretchability (a fracture strain up to 1700%), self\u2010healing ability (a healing efficiency of 88% and 97% for the mechanical and electrical properties, respectively), and 4D printability of the hydrogel are demonstrated by constructing a strain sensor, a two\u2010dimensional touch panel, and shape\u2010morphing structures with water\u2010responsive behavior. The hydrogel demonstrates vast potential for applications in stretchable electronics.\n                  <\/jats:p>","DOI":"10.1002\/advs.202305702","type":"journal-article","created":{"date-parts":[[2024,1,24]],"date-time":"2024-01-24T02:56:15Z","timestamp":1706064975000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["Self\u2010Healable and 4D Printable Hydrogel for Stretchable Electronics"],"prefix":"10.1002","volume":"11","author":[{"given":"Huijun","family":"Li","sequence":"first","affiliation":[{"name":"Singapore Centre for 3D Printing, School of Mechanical and Aerospace Engineering Nanyang Technological University  50 Nanyang Avenue Singapore 639798 Singapore"}]},{"given":"Chin Boon","family":"Chng","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, College of Design and Engineering National University of Singapore  9 Engineering Drive Singapore 117575 Singapore"}]},{"given":"Han","family":"Zheng","sequence":"additional","affiliation":[{"name":"Singapore Centre for 3D Printing, School of Mechanical and Aerospace Engineering Nanyang Technological University  50 Nanyang Avenue Singapore 639798 Singapore"}]},{"given":"Mao See","family":"Wu","sequence":"additional","affiliation":[{"name":"Singapore Centre for 3D Printing, School of Mechanical and Aerospace Engineering Nanyang Technological University  50 Nanyang Avenue Singapore 639798 Singapore"}]},{"given":"Paulo Jorge Da Silva","family":"Bartolo","sequence":"additional","affiliation":[{"name":"Singapore Centre for 3D Printing, School of Mechanical and Aerospace Engineering Nanyang Technological University  50 Nanyang Avenue Singapore 639798 Singapore"}]},{"given":"H.
