Flexible/soft tactile sensors enable the robotic arms to gain real‐time mechanical responses, which are of utmost importance for future deep learning in robotic sciences and technologies. Learning from nature will inspire the advances of soft tactile sensors as mother nature is proficient in achieving unique functionality at the simplest construction. Herein, the fabrication of self‐powered soft tactile sensors is reported. The shape of flexible sensors mimics Merkel's disks, allowing for a well tactile perceptual functionality. Due to the use of flexible magnetoelectric materials, the sensors are self‐powered without external power supply. This unique functionality is explained by Maxwell's numerical simulation, allowing for further improvement of their performance by adjusting diverse fabrication factors. Furthermore, such self‐powered soft tactile sensors are attached to the tips of a robotic arm, enabling the arm to distinguish different objects after smart learning. The soft sensor design reported here is expected to manifest in a range of self‐powered sensing systems, opening up as yet unexplored avenues for the development and the exploitation of future intelligent robots and their deep learning.

Ions transport through confined space with characteristic dimensions comparable to the Debye length has many applications, for example, in water desalination, dialysis, and energy conversion. However, existing 2D/3D smart porous membranes for ions transport and further applications are fragile, thermolabile, and/or difficult to scale up, limiting their practical applicability. Now, polymeric carbon nitride alternatively allows the creation of an ultrathin free-standing carbon nitride membrane (UFSCNM), which can be fabricated by simple CVD polymerization and exhibits excellent nanofluidic ion-transport properties. The surface-charge-governed ion transport also endows such UFSCNMs with the function of converting salinity gradients into electric energy. With advantages of low cost, facile fabrication, and the ease of scale up while supporting high ionic currents, UFSCNM can be considered as an alternative for energy conversion systems and new ionic devices.

Biological soft robots have attracted extensive attention and research because of their superiority in executing designed biomedical missions compared with conventional robots. Here, inspired by the crawling mechanism of snakes and caterpillars, a novel biological soft robot composed of asymmetric claws, a carbon nanotube (CNT)-induced myocardial tissue layer, and a structural color indicator is presented. The asymmetric claws can assist the whole soft robot to accomplish directional movement during the cardiomyocytes' contraction process. The oriented conduct of the CNT layer can regulate the cardiomyocytes' arrangement and improve their beating capability and the contraction performance. However, the structural color indicator provides a visualized monitoring approach to dynamically and immediately reflect the motion status of the biological soft robots. With these three functional layers, the cardiomyocyte-driven soft robot can greatly simulate the crawling behavior of a caterpillar. It is demonstrated that by integrating these soft robots in a microfluidic organ-on-a-chip system with multitrack construction, they can run along the tracks and exhibit different running speed based on the stimulus concentrations in the tracks. These features indicate the potential values of the cardiomyocyte-driven soft robots for providing an effective screening platform for clinical diseases.
