Magnetic soft robots exhibit attractive advantages such as nontethered constraints and remote control capabilities, with broad prospects in environmental exploration, minimally invasive surgery other fields. However, constrained by the magnetic mode high flexibility of materials, achieving rapid movement perception-feedback are still challenging. Therefore, this paper aims to draw inspiration from biomimetic joint structures design fabricate a arthropod robot capable cyclic extension-contraction deformation under an alternating field. First, type A (MASR-A) is developed speed up 1.4 body length per second (BL/s) three-joint-unit. Next, we designed B (MASR-B) that offers higher adaptability bodies owing five-joints structure. Then, inspired snail's tentacles, bionic antennae based on triboelectric tactile sensors (TTSs), which can convert external mechanical collisions into electrical signals output, sensitivity 0.13 V KPa−1. By mounting head MASR-B realize robot's sensing function, enabling detect obstacles various materials (PMMA, Resin, PLA etc.). Particularly, consists two completely independent units (LTTS RTTS). The these TTSs received identified microcontroller determine direction obstacle relative robot. relay then controlled alter field generated electromagnetic coils enable avoid obstacle. This provides approach for flexible robots.

Emerging soft robots based on liquid crystal elastomers (LCEs) exhibit remarkable capabilities for large reversible shape morphing, enabling them to adapt complex environments and perform diverse tasks such as locomotion camouflage. Despite extensive studies, current methods locally controlled actuation of LCE-based often involve intricate structural design, programming LCEs, incorporation multiple materials, or methods. Here, we present a simple efficient approach achieve deformation modes within simply programmed LCE structure by harnessing Joule heating-induced thermal gradients across the volume. Oxidized metal (LM) thin films, which increased resistance, enhanced viscosity, high conductivity, deformability, are employed heating in this study. Using an strip via uniaxial stretching example, systematic studies effect essential parameters, including voltage, dimensions, LM-to-LCE thickness ratio, behaviors LCEs induced three-dimensional In addition, concurrently actuating two adjacent surfaces yields previously inaccessible coupled bending behaviors. Finally, demonstrate crawling robot constructed from LM-coated strips with adjustable capabilities, enable multimode locomotion, forward movement turns, enhancing biomimetic functionality akin leg movements observed living organisms like reptiles. The reported strategy, is both straightforward versatile, promises scalability holds potential various applications multifunctional intelligent systems robotics biomedical devices.

Implantable medical devices (IMDs) provide effective solutions for diverse health care applications. Electrical circuits are crucial implantable due to the requirement of intended functions, such as communication with external devices. Circuits have several risks, biocompatibility issues, power limitations, or size constraints. In this work, we propose a passive modulated ultrasound (PMU) principle IMDs and develop circuit-free ultrasonic system (CUS) thoracic pressure monitoring. The PMU can passively modulate monitored physiological signals into pulses without using electrical supply. developed CUS is only 2.5 millimeters in radius 850 micrometers height. Animal experiments demonstrated that CUS, high sensitivity (−22.96 millivolts per kilopascal), monitor assist diagnosing different heart diseases, including cardiac arrest myocardial infarction. provides human-friendly wireless sensing strategy IMDs, which promotes advancements applications within human body.
