A strategy for bonding water-rich hydrogels to diverse materials electronic skins, energy storage, and soft optics is reported.
We present soft electromagnetic actuators from liquid metal and elastomer that are safe, stretchy, fast, durable, programmable.
Abstract Acting at high speed enables creatures to survive in their harsh natural environments. They developed strategies for fast actuation that inspire technological embodiments like soft robots. Here, we demonstrate a series of simulation-guided lightweight, durable, untethered, small-scale soft-bodied robots perform large-degree deformations frequencies up 100 Hz, are driven very low magnetic fields down 0.5 mT and exhibit specific energy density 10.8 kJ m −3 −1 . Unforeseen asynchronous...
Embedded sensors are key to optimizing processes and products; they collect data that allow time, energy, materials be saved, thereby reducing costs. After production, remain in place used monitor the long-term structural health of buildings or aircraft. Fueled by climate change, sustainable construction such as wood fiber composites gaining importance. Current not optimized for use with these often act defects cause catastrophic failures. Here, flexible, highly permeable, imperceptible...
Surgical simulators are safe and evolving educational tools for developing surgical skills. In particular, virtual hybrid preferred due to their detailedness, customization evaluation capabilities. To accelerate the revolution of a novel class simulators, Smart Artificial Soft Tissue is presented here, that determines relative position conductive instruments in artificial soft tissue by inverse resistance mappings without need fixed reference point. This particularly beneficial highly...
Epidural and spinal anesthesia are mostly performed "blind" without any medical imaging. Currently, training of these procedures is on human specimens, virtual reality systems, manikins in clinical practice supervised by a professional. In this study novel hybrid, low-cost patient simulator for the needle insertion into epidural space was designed. The phantom provides realistic force feedback comparable with biological tissue enables sensing tip position during insertion. A display delivers...
Wearable healthcare devices monitor the condition of patients outside hospital and hence increase treatment capacity resources. At same time, benefit from wireless data transmission conformable device designs, speeding up rehabilitation process integration into normal daily activities. Yet, successful implementation personalized creates an extensive engineering challenge as need to adapt a vast number different protocols. Herein, soft building blocks mobile health (mHealth) that reversibly...
Paper-Based Sensors iSens are flexible, foldable, and translucent paper-based sensors. The porous substrates consist of a fiber structure that is highly permeable to liquids. Interdigital electrodes made ultrathin copper individually designed by one step laser ablation. This platform, presented Martin Kaltenbrunner co-workers in article number 2102736, will contribute new generation imperceptible sensors seamlessly integrated into smart composite materials.
Stretchable Electronics The image, provided by Martin Kaltenbrunner and co-workers (article number 2000065), shows magnetic interfaces serving not only as mechanical but also electrical connectors in stretchable electronics. These are safeguarded a controlled release mechanism, preventing failure every-day operation allow modular user-friendly approach to the assembly of mHealth devices.
