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.

“…[ 226 ] Using the flexible magneto‐electric materials, Wu et al manufactured a self‐powered out‐of‐plane wind sensors through mimicking trichobothria of spiders (Figure 20j). [ 215 ] This sensor consists of three parts, which are support substrate, electrical and magnetic. By utilizing screen printing technique, silver nanoparticles were patterned on the polyethylene terephthalate film and the artificial cilium was fabricated in triangle shape.…”

Bionic engineering provides a promising way for promoting the development of science and technology. Next‐generation diversified mechanosensors that can efficiently sense four types of mechanical signals, including tactile, vibration, air/water flow, and sound, are also benefiting from the bioinspired approach. Natural organisms have evolved sophisticated biological mechanosensilla with excellent performance, such as ultrahigh sensitivity, resolution, stability, anti‐interference, and miniaturization, providing a great deal of inspiration for urgently needed mechanosensors that are difficult to achieve through conventional methods. Here, the recent advances in biological mechanosensilla and corresponding bioinspired mechanosensors are reviewed in detail. According to the classification of the mechanosensilla, i.e., tactile sensilla, vibrational sensilla, flow sensilla, and acoustic sensilla, this review is mainly divided into four parts. In each part, the research on functional mechanisms of the mechanosensilla based on well‐organized mechanosensory micro/nanostructures and unique functional materials, as well as the bionic design strategy and preparative technique of bioinspired mechanosensors are individually summarized and discussed. Meanwhile, insight into the further efforts in comprehensive understanding of the mechanosensilla, learning from the multiperformance integration of sensilla, and establishing the efficient preparation methods for bioinspired mechanosensors is provided, all of which are needed to be addressed urgently before having bioinspired mechanosensors of practical value.

Skin‐like wearable sensors are regarded as key technologies toward home‐based healthcare, human–machine interfaces, robotics, prostheses, and enhanced augmented/virtual reality (AR/VR). Inspired by human somatosensory functions, artificial sensory feedback systems play vital roles in shaping interactions with complex environments and timely decision‐making. This study presents an overview of recent advances in feedback‐driven, closed‐loop skin‐inspired flexible sensor systems that make use of emerging functional nanomaterials and elaborate structures. Drawing on feedback solutions, four categories of sensor systems are highlighted, which include prosthesis‐ and AR/VR‐based human–machine interfaces, smartphone‐based approaches for point‐of‐care detection, and smart wearable displays for direct signal visualizations. Furthermore, the progress of machine learning on the reliable recognition of massive quantities of signals generated by flexible sensor networks is briefly discussed. The state‐of‐the‐art hybrid sensor techniques, along with other emerging strategies, will enable total sensory feedback loop systems to be developed for next‐generation electronic skins.
