Accurate local stiffness control is of considerable significance to the design and application of 3D variable\u2013stiffness structures although it is challenging. Herein, a 3D variable\u2013stiffness structure realization scheme based on a patterned heating network is introduced. The laser\u2010engraving and 3D\u2010printing technologies are combined to obtain a 3D variable\u2013stiffness structure composed of a patterned graphene\u2010heating network (PGHN) and polylactic acid (PLA). The proposed scheme uses PGHN to accurately control the local stiffness of 3D PLA and realize programmable design and fabrication of 3D variable\u2013stiffness structures. The \u201ctorsional structure,\u201d \u201chexagonal structure,\u201d and \u201cspring\u201d cases are used to elaborate the designability, excellent deformation and reconstruction capacity, and reasonable load bearing capacity of the PGHN\/PLA variable\u2013stiffness structure. A pneumatic disc, which is used as a reference for studies on shape control of PGHN\/PLA variable\u2013stiffness structures, is designed. Also, a pneumatic robot is designed based on the local stiffness control and shape\u2010locking function of PGHN\/PLA to achieve multimode motion control using a single air source. The PGHN\/PLA variable\u2013stiffness structure has potential applications in multimode robots, wearable devices, and deployable structures.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202300032","type":"journal-article","created":{"date-parts":[[2023,4,7]],"date-time":"2023-04-07T04:26:17Z","timestamp":1680841577000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Programmable Design and Fabrication of 3D Variable\u2013Stiffness Structure Based on Patterned Graphene\u2010Heating Network"],"prefix":"10.1002","volume":"5","author":[{"given":"Qi","family":"Wang","sequence":"first","affiliation":[{"name":"Jiangsu Collaborative Innovation Centre for Photovoltaic Science and Engineering Changzhou University  Changzhou 213164 P.
