More recently, soft actuators have evoked great interest in the next generation of soft robots. Despite significant progress, the majority of current soft actuators suffer from the lack of real‐time sensory feedback and self‐control functions, prohibiting their effective sensing and multitasking functions. Therefore, in this work, a near‐infrared‐driven bimorph membrane, with self‐sensing and feedback loop control functions, is produced by layer by layer (LBL) assembling MXene/PDDA (PM) onto liquid crystal elastomer (LCE) film. The versatile integration strategy successfully prevents the separation issues that arise from moduli mismatch between the sensing and the actuating layers, ultimately resulting in a stable and tightly bonded interface adhesion. As a result, the resultant membrane exhibited excellent mechanical toughness (tensile strengths equal to 16.3 MPa (||)), strong actuation properties (actuation stress equal to 1.56 MPa), and stable self‐sensing (gauge factor equal to 4.72) capabilities. When applying the near‐infrared (NIR) laser control, the system can perform grasping, traction, and crawling movements. Furthermore, the wing actuation and the closed‐loop controlled motion are demonstrated in combination with the insect microcontroller unit (MCU) models. The remote precision control and the self‐sensing capabilities of the soft actuator pave a way for complex and precise task modulation in the future. [ABSTRACT FROM AUTHOR]

Manufacturing flexible integrated sensing systems by combining versatile printable inks and diverse printing techniques allows for the monolithic utilization of the electrochemical/sensing performance of individual devices. Herein, we developed an integration strategy for fabricating high-performance flexible integrated sensing systems by utilization of multi-dimensional printable MXene electrodes. With branched polyethyleneimine (BPEI) serving as joining sites and flexible spacers, the flexible printed electrodes exhibited weak self-restacking, high interlayer charge carrier transporting ability, and remarkably enhanced mechanical robustness. As a result, the printed micro-supercapacitors (MSCs) showed ultrahigh areal capacitance (3783.53 mF cm−2 at a scan rate of 1 mV s−1), outstanding flexibility (stable after 1000 bending/release cycles), high energy density (99.4 μW h cm−2) and high power density (18 mW cm−2). Besides, the printed strain sensor board displayed high sensitivity over a wide working strain range (e.g., gauge factor: 11 781.5 in the 41–52% strain range). These results represent the record values in most state-of-the-art devices. In addition, an all-in-one flexible sensing system integrated with both an MSC and a strain sensor on a flexible substrate is demonstrated, which exhibited exceptional sensitivity to body movements. This proposed strategy paves a high-efficiency pathway toward high-performance, monolithically integrated electronics. [ABSTRACT FROM AUTHOR]
