“…coalescence, coarsening and drainage) that inevitably disrupt the liquid foam. 46,47 Both the ChitH and the CellH solutions proved to be not viscous enough to stabilise a foam. For this reason, we decide, on an empirical basis, to partially cure the ChitH pre-polymeric solution for 35 min and the CellH one for 20 min before starting the fluid-assisted foaming.…”

“…So that they are able to change their shapes and forms, squeeze through confined spaces, and manipulate objects dexterously to adapt to different tasks and environments. [2] Elastomeric materials generally include hydrogels, [3][4][5] hyperelastic materials, [6][7][8] dielectric elastomeric materials, [9][10][11] polydimethylsiloxane (PDMS), [12] carbonbased materials, [13][14][15] shape-memory alloys, [16][17][18] shape-memory polymers, [19] and other flexible materials, which are well suited for applications under specific conditions. However, hydrogel and carbon-based materials have poor mechanical properties.…”

Bio‐inspired micro soft robots mimic biologically specific body structures and movement mechanisms by utilizing bionic principles. Because of its soft body, it can adapt to complex external environments. However, the existing polymer material system is single and the fabrication process is limited. How to further reduce soft robot size has become a key issue. In this work, a Programming Magnetic Elastic Composites (PMEC) is proposed for 3D printing to manufacture micro soft robots. The PMEC has the advantage of changing the direction of the internal magnetic field in response to changes in the external magnetic field. A Microsoft robot is designed and fabricated using PMEC inspired by an inchworm. Numerical simulations are also used to study the effect of soft robot size parameters on local stresses and optimize the structure. The results show that the microscale soft robot can crawl with a load of 2 times its weight at a speed of 6.67 mm s−1, crawl on slopes from 0° to 90°, and crawl over obstacles with a maximum height of 7 mm. In addition, active adaptation of soft robots to complex tunnel models based on external stimuli is achieved by magnetic field control.

“…However, toward the rich application scenarios, for instance, personalized medicine [ 1 , 2 ], chemical sensors [ 3 ], personal motion monitoring [ 4 ], personalized electronic device customization [ 5 ], and so on, the true potential of IoT can only be realized if they are made self-sustainable, either by reducing the power consumption of the IoT through ultra-low-power-consumption circuits and low-voltage operation, or combining them with energy-harvesting technologies and making more energy available, or in most cases, hand in hand [ 6 , 7 , 8 ]. Meanwhile, as an emerging and ever-growing technological field, another challenging issue is to make flexible electronic materials as well as integrated power sources both durable and powerful in strained states, especially for applications such as skin-like electronics, implantable biodegradable devices [ 9 , 10 , 11 ], and bioinspired soft robotics [ 12 , 13 , 14 , 15 , 16 ]. Highly stretchable and biocompatible energy technologies will greatly boost the development of next-generation intelligent lifelike electronics [ 17 , 18 ].…”

There is an increasing need for structural flexibility in self-powered wearable electronics and other Internet of Things (IoT), where adaptable triboelectric nanogenerators (TENGs) play a key role in realizing the true potential of IoT by endowing the latter with self-sustainability. Thus, in this review, the topic was restricted to the adaptive design of TENGs with structural flexibility that aims to promote the sustainable operation of various smart electronics. This review begins with an emphatical discussion of the concept of flexible electronics and TENGs, and continues with the introduction of TENG-based self-powered intelligent systems while placing the emphasis on self-powered flexible intelligent devices. Self-powered healthcare sensors, e-skins, and other intelligent wearable electronics with enhanced intelligence and efficiency in practical applications due to the integration with TENGs are illustrated, along with an emphasis on the design strategy of structural flexibility of TENGs and the associated integration schemes. This review aims to cover recent achievements in the field of self-powered systems, and provides information on how flexibility or adaptability in TENGs can be adopted, their types, and why they are required in promoting advanced IoT applications with sustainability and intelligence algorithms.
