A review of 4D printing
TL;DR: A comprehensive review of the 4D printing process is presented in this article, which summarizes the practical concepts and related tools that have a prominent role in this field and summarizes the unimportant aspects.
Journal ArticleDOI
Plant leaf-mimetic smart wind turbine blades by 4D printing
TL;DR: A new paradigm for design and fabrication of wind blades is demonstrated by 4D printing process, which combines several beneficial attributes in one blade that can show reversible bend-twist coupling (BTC) and lead to eco-friendly wind turbines.
Journal ArticleDOI
Nature-inspired smart solar concentrators by 4D printing
Farhang Momeni,Jun Ni +1 more
TL;DR: This work is inspired by diurnal and nocturnal flowers and their differences and proposes a smart solar concentrator that can increase the overall optical efficiency more than 25% compared with its non-smart counterparts.
Journal ArticleDOI
Laws of 4D Printing
Farhang Momeni,Jun Ni +1 more
TL;DR: By starting from fundamental concepts, a universal bi-exponential formula is derived and validated that is required to model and predict the fourth D of 4D printed multi-material structures and it is demonstrated that two different types of time-constants govern the shape-shifting behavior of almost all the multi- material 4D printing structures over time.

Laws of 4D printing
Farhang Momeni,Jun Ni +1 more
TL;DR: In this paper, the authors derive and validate a universal bi-exponential formula that is required to model and predict the fourth dimension of 4D printed multi-material structures, and reveal three general laws that govern the time-dependent shape-shifting behaviors of almost all (photochemical-, photothermal-, solvent-, pH-, moisture-, electrochemical-, electrothermal-, ultrasound-, enzyme-, etc.-responsive) multilayer 4D structures.
