This article offers a thorough review of the current state-of-the-art in four-dimensional (4D) printed antennas and possible adaptable designs. It provides a succinct examination of various categories of materials used in three-dimensional (3D) and 4D printing, including the utilization of smart materials available in both printable and synthesized forms. The review encompasses a concise analysis of fabrication techniques, stimuli, and response behaviors applied in various types of smart materials. These materials have the potential to fabricate antennas with tunable and reconfigurable properties, including frequency of operation, bandwidth, gain, and radiation pattern. Given the novelty of applying 4D printing in antenna technologies, the review also considers additional reconfigurable antennas with mechanically tunable properties, as well as those in non-printed formats. This exploration hints at potential adaptations to the latter for the development of 4D printed antennas. The utilization of 4D printing presents a complex yet intriguing approach to antenna fabrication, offering the possibility of creating dynamic antennas with sophisticated characteristics.

“…The shape memory characteristics of SMPs provide possibilities for the design of large deformable and deployable structures. Thus, SMPs are widely used in various fields, including aerospace, smart actuators, and biomedicine [20][21][22][23][24]. The deploying process of deployable structures actuated by SMP is slower, low impact, and more controlled than traditional elastic or bi-stable structures, as compared in supplementary video S1.…”

Deployable drag sails are used for passively deorbiting defunct satellites and other spacecraft. Designing the deployable boom is the main challenge in this technology. We present a bi-stable shape memory polymer composite (Bi-SMPC) boom with high stiffness, a high unfolding/folding ratio, and consistent roll-out deployment. It was designed and fabricated by a strategy of controlling the gradual release of elastic energy stored in a bi-stable composite structure through thermal-driven shape memory polymer matrix. Two heating layer strategies were investigated experimentally to determine the optimal driving layer and driving parameters. Based on these parameters, verification tests of a four-stage deployment Bi-SMPC boom were conducted. Meanwhile, a proof-of-concept prototype of a four-stage deployment drag sail based on the Bi-SMPC booms was designed and fabricated. Tests were conducted to verify the effectiveness of the drag sail deployed by the booms. It was found that shape memory polymers can effectively control the deployment of bistable composite structures. The nickel-chromium alloy heating layer offers a more uniform driving temperature field compared to carbon fiber. The drag sail can be deployed successfully under the driving of four Bi-SMPC booms.

“…Stimulations' forms could include thermal drive [17,18], electric drive [19,20], optical drive [21,22], magnetic drive [23,24] and chemical drive SMP [25,26] and so on. Since the thermal-driven stimulation is easy for changing the SMP shape, thermaldriven SMPs have wide range of applications [27], such as aerospace [28], biomedical [29,30], soft robot [31] and electronic components fields [32]. Ming et al studied a deployable SMP parabolic reflector based on thermal-driven method [28].…”

The traditional rebar binding devices require complex drive and transmission mechanisms, which leads to large volume and complex structure. In this paper, a cylindrical thermoplastic shape memory polymer (SMP) fixture is proposed to verify the rebar binding method of thermal-mechanism coordination. The SMP fixture is manufactured by the injection molding technology through selecting suitable-ratio Polylactic acid (PLA) and Polycaprolactone (PCL) blend materials. Besides, an additional auxiliary device is presented to overcome the incomplete recovery disadvantage existing in the thermoplastic SMP and completely achieve binding the rebar. On this base, two different binding methods are proposed to compare the mechanical performance after fixing the rebar, and the external force/thermal contributions are tested and discussed in detail. The tested results show that the binding contribution of heat could reach 70% while the binding contribution of external force could reach 30% above the transition temperature (Tg). The maximum tensile force that the binding rebar can withstand under the thermal-mechanism coordination action could reach up to 657.7 N, which is higher than the maximum tensile force of the wire binding. In addition, the maximum friction force between rebar and notches of fixture could reach up to 94.1 N, which further verifies the feasibility of thermal-mechanism coordination for binding reinforcing mesh based on SMP fixture.
