Summary: To enable soft robotics to be intelligent, researchers have developed impressive artificial skin and actuators. However, the complex demands of raw materials pose a challenge for autonomous soft actuators to achieve manufacturing repeatability and reproducibility, unlike their rigid counterparts. Inspired by stem cells, a potential multifunctional gel with salt-induced regulating module, conductivity, and other bionic properties has been introduced. This gel serves as a dual-purpose electrode for actuation and sensing, enabling the formation of an artificial reflex arc through tight integration with an e-brain. This efficient strategy shows promise in effortlessly fabricating fully soft robotics with minimal raw materials.

Summary: Lattice structures, especially when integrating gradient and composite/structural designs, have become functional structures, but lack sufficient intelligence for interacting with the environment. Inspired by the human skeletal-muscle-skin system, this study proposes an intelligent structure by interpenetrating low-stiffness and high-stiffness material structures in a gradient manner and designing media transfer channels for touch perception. The structure achieves accurate and large-coverage collision detection with excellent load-bearing capacity. Gradient design improves damage pattern and enhances mechanical properties, with a 59.9% increase in compression modulus. Soft-and hard-composite design further increases energy absorption capacity by over 100% and effectively limits catastrophic damage. The structure has great potential for applications such as intelligent interactive robots requiring load-bearing and collision detection capabilities.
