“…Tactile perceptual functioning and smart learning are the trends of the next‐generation robot developments . Due to the advanced piezoelectric capacity of the hemisphere‐shaped sample (Figure t), the self‐powered sensor was carefully attached to one tip of a robotic arm (Figure a–c), allowing the robotic arm to feel and then respond to diverse objects.…”

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.

[3-5] Furthermore, generating electricity using a traditional electromagnetic apparatus is difficult under low water supply, such as rainwater or fog. [6] Therefore, a small, novel, and portable electromagnetic system that can harvest energy from tiny water drops can act as a water-electricity transducer; such a system is an alternative to traditional hydropower equipment. Bioinspired superhydrophobic materials have low surface energy and microor nano-scale surface roughness, [7-9] rendering their unique capability to manipulate water droplets. By carefully designing and controlling the superhydrophobic surfaces, water drops can pin, [10] roll, [11] separate, [12] jump, [13] and react [14] and, therefore, can possess a variety of

Flexible magnetic field sensors attract significant interests in magnetic detection and flexible electronics. However, two challenges, low sensitivity, and limited working range, impede their practical application. Herein, a new type of magnetic‐sensitive crack sensor (M‐CS) by depositing graphene nanosheets upon a flexible magnetic film through a facial infrared drying technique is reported. The M‐CS exhibits an ultrahigh sensitivity (relative resistance change up to 4.0 × 1010) toward a moderate magnetic field of 43 mT at room temperature. In addition, the M‐CS shows a long cycling stability over 10 000 cycles. Such a superior sensitivity is attributed to physically cutting/recovering the pathways of electron transport through nanosheets’ separation/contact. Diverse experimental parameters, such as the concentration of graphene solution and the thickness of bottom magnetic substrates, have been tailored to improve the magnetic sensitivity of M‐CS. Furthermore, the array of M‐CSs with different relative resistance change can be used as the cipher key to recognize aimed magnetic signal without contact. It is believed that the M‐CS with an ultrahigh magnetic sensitivity at operational condition and long‐term stability could benefit the development of magneto‐sensitive sensors, and exploit the application of 2D materials in flexible electronic devices.
