Along with the development of material systems and fabrication techniques, mechanical design principles for additive manufactured soft materials were greatly developed and evolved over the past few years, and some special issues that are distinct from conventional manufacturing techniques emerged. In this short review, we mainly focus on additive manufactured soft materials that are in great request of mechanical models/simulations to provide design guidelines, therefore, topics such as soft robotics and electronics are out of scope here. We firstly discuss the mechanical designs for controlling shape distortions and interfacial strength, as they are directly related to the quality and reliability of additive manufactured soft materials. Then, design principles and manufacturing strategies for bio-inspired composites, which makes up a large part of current researches on additive manufactured soft materials, are summarized integrally from three aspects. In addition, basic mechanical considerations for additive manufactured 4D shape changing structures are explained, together with the review of recent theories and numerical approaches. Finally, suggestions and perspectives are given for future developments of soft material additive manufacturing.","PeriodicalId":74837,"journal":{"name":"Soft science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67660036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, current e-skins are still relatively thick (> 10 µ m) and uncomfortable for long-term usage on the human body. Herein, an ultrathin skin-integrated strain sensor with miniaturized dimensions, based on the piezoresistive effect, with excellent stability and robustness, is introduced. The fractal curve-shaped Au electrode in a serpentine format, which is the dominant component of the strain sensor, is sensitive to ambient strain variations and can turn the mechanical motion into a stable electrical signal output. With the advanced design of metallic electrodes, the device presents good operational stability and excellent mechanical tolerance towards bending, stretching and twisting. The stain sensor allows intimate mounting onto the human epidermal surface for the detection of body motion. By adopting a liquid bandage as an encapsulation layer, the device exhibits an ultrathin thickness (6.2 µ m), high sensitivity towards mechanical deformations and capability for the clear","PeriodicalId":74837,"journal":{"name":"Soft science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45597523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
