“…25,27 Super-oleophobic low adhesion surface with self-healing capacity was prepared through constructing a hierarchical micro/ nanostructure on epoxy shape memory polymer (ESMP) and modifying (3-Aminopropyl) triethoxysilane (APTES). 28 In the past few years silicon rubber (SR)-based composites have received much attention due to their unique characteristics, such as low toxicity, chemical stability, low-temperature toughness and low-surface energy. 16 For strain sensors layer, polymer matrix with high flexibility and easy processing was crucial.…”

Flexible strain sensors based on conductive fillers and flexible polymers possessed significant advantages in human motion detection. Preparing a strain sensing layer with high electrical conductivity and excellent mechanical property under high content of conductive filler contributed to the stability of flexible strain sensors. In this study, MWCNTs/PDMS composite film was prepared by the organic solvent method. The microstructure, electrical conductivity, mechanical property, and piezoresistive characteristics of the composite film at different MWCNTs contents were characterized and discussed. When the mass fraction of MWCNTs in the composite film was 5%, the composite film exhibited a high electrical conductivity of 9.56 S/m while maintaining ideal mechanical properties, and the film thickness was just about 180 μm. The relationship between electrical signals and film strain was performed. The piezoresistive characteristic results demonstrated that the prepared composite film could be used as flexible strain sensor for human motion detection. The prepared thin MWCNTs/PDMS composite film in this paper illustrated high conductive and desired flexibility, and was an alternative material for human motion detection.

“…Besides, they also have various important potential applications in wireless communication, , underwater communication, renewable energy, and decarbonization . The Internet of Underwater Things (IoUT) is defined as a worldwide network of smart interconnected underwater objects; IoUT has broad application prospects in the civil and military fields, and therefore, underwater studies play an important role in IoUT, such as an underwater superoleophobic low adhesion surface with self-healing capacity, underwater–waterproof electrical devices, , and high-efficiency signal transmission systems . Most smart gloves are based on airtight film-based sensor arrays.…”

Rapid advancements in immersive communications and artificial intelligence have created a pressing demand for high-performance tactile sensing gloves capable of delivering high sensitivity and a wide sensing range. Unfortunately, existing tactile sensing gloves fall short in terms of user comfort and are ill-suited for underwater applications. To address these limitations, we propose a flexible hand gesture recognition glove (GRG) that contains highperformance micropillar tactile sensors (MPTSs) inspired by the flexible tube foot of a starfish. The as-prepared flexible sensors offer a wide working range (5 Pa to 450 kPa), superfast response time (23 ms), reliable repeatability (∼10000 cycles), and a low limit of detection. Furthermore, these MPTSs are waterproof, which makes them well-suited for underwater applications. By integrating the high-performance MPTSs with a machine learning algorithm, the proposed GRG system achieves intelligent recognition of 16 hand gestures under water, which significantly extends real-time and effective communication capabilities for divers. The GRG system holds tremendous potential for a wide range of applications in the field of underwater communications.

Reducing the weight and profile of machinery and robotics is currently a prime challenge for materials scientists and engineers alike. Solving this challenge could lead to an improvement in space travel feasibility, manufacturing capability, and the birth of new medical interventions and technologies altogether. LCEs are currently considered to hold good potential as artificial muscles due to their unique molecular structure. With the recent boom in materials science and the emergence of advanced fabrication techniques, LCE-based artificial muscles/flexible actuators are at the cusp of commercialization. LCEs can now be fabricated into several different forms (films, fibers, and 3D printed arbitrary shapes). Furthermore, LCE artificial muscles fabricated using these advanced techniques can also be functionalized so that they can controllably be triggered into actuating via stimuli such as light or electrical currents. This has led to reports of several LCE-based artificial muscles which boast impressive performance as artificial muscles. For example, recently certain Joule heating LCE fibers can directly be stimulated into actuation via the application of electrical currents and can actuate on sub-second time frames and outperform human skeletal muscles in terms of actuation stress. Given this, whilst currently there are no commercial applications of LCEs as artificial muscles in robotics, we believe that LCEs are poised to soon be directly applicable as artificial muscles in the broader field of robotics, which inspired us to author this review. This review presents an overview of the mechanisms, synthetic methods, and alignment methods for LCEs. In addition, we provide the latest achievements in fabrication techniques and means of inducing/controlling the actuation of LCEs. We do so in the aspiration that this review can bridge the gap that exists between academia and industry on the topic of LCEs. Graphical abstract Illustration of LCEs acting as artificial muscles in robotics.
