“…Recent research has illuminated the potential of light-triggered actuation, where sensors monitor the integration of supercapacitors and thermos-responsive liquid crystalline polymer networks, facilitating the direct conversion of light into motion. 10 In other research, electronics-free soft pneumatic circuits powered by mini CO 2 cylinders have been explored, hinting at a future where sensors could regulate artificially cultured soft pumps. Flexible organic solar cells, 11 equipped with sensors to optimize energy capture, present another avenue.…”

Soft robotics, offering precise actions in complex environments, stands at the brink of transformative advancements across diverse fields. To realize this potential, the field must address five key challenges: creation of soft power and control mechanisms, emphasis on sustainability, cultivation of advanced intelligence, and the imperative for standardization. This perspective argues for solutions grounded in sensory feedback systems, aiming to fortify the foundation of soft robotics, ensure its sustainability, enhance adaptability in robot intelligence, and set the stage for scalable robot production. Addressing these challenges, we aim to pave the way for a more inclusive era of soft robotic technology.

“…In the production of programmable LCPs, the use of grafting technologies, such as photopatterning and 3D printing, is widely employed. , This approach has significant implications for the development of advanced artificial organs, such as high-power human muscles . Notably, LCPs possess the ability to split along cracks or adjust their folding direction based on the initial orientation of the LC. ,, This distinctive characteristic allows for precise control and customization of the LCP structure, thereby opening up new possibilities for tailored applications such as wrinkle structures. , …”

The capability of liquid crystals (LCs), that instantaneously modulate their physical and chemical properties in response to a target stimulus, found a killer application of liquid crystal displays (LCDs) and has made LCs one of the most widely used materials. The use of LCs, however, is not restricted to LCDs. Over decades, a range of characteristic features of LCs has been unveiled and opened access not only to the fundamental knowledge gap but also to a rich variety of applications beyond LCDs, including the measurement of Casimir torque, nonlinear electrophoresis, the morphology of the topological defect, colloidal/molecular templates, sensors, actuators, and controlled release systems. Here, we review how the unique properties of LCs have been leveraged and provided insights into the design of stimuli-responsive materials and their applications.

“…Contrarily, liquid crystal elastomeric polymer networks (LCEs) are emerging materials currently in development possessing application-specific characteristics, such as artificial muscles for soft robotics. 9–29 Molecularly aligned LCEs exhibit anisotropic macroscopic deformation typically in response to heat by programming molecular alignment. 30–32 By temperature change, the LCEs undergo order-to-disorder transformation due to nematic–isotropic phase transition and, as a result, contraction along the molecular director takes place.…”
