In situ integrated microrobots driven by artificial muscles built from biomolecular motors.

Science robotics
Microrobots have been developed for applications in the submillimeter domain such as the manipulation of micro-objects and microsurgery. Rapid progress has been achieved in developing miniaturized components for microrobotic systems, resulting in a v...

Programmable Auxeticity in Hydrogel Metamaterials via Shape-Morphing Unit Cells.

Advanced science (Weinheim, Baden-Wurttemberg, Germany)
Mechanical metamaterials recruit unique mechanical behavior that is unavailable in bulk materials from a periodic unit cell structure with a specific geometry. However, such metamaterials can typically not be reconfigured once manufactured. Herein, t...

A biomimetic elastomeric robot skin using electrical impedance and acoustic tomography for tactile sensing.

Science robotics
Human skin perceives physical stimuli applied to the body and mitigates the risk of physical interaction through its soft and resilient mechanical properties. Social robots would benefit from whole-body robotic skin (or tactile sensors) resembling hu...

Small-scale soft grippers with environmentally responsive logic gates.

Materials horizons
Small-scale soft grippers are adaptive and deformable, and can be utilized for confined environments (, the human body). Small-scale soft grippers require logic-based computation to achieve intelligent control and perform logical analysis of the surr...

Methods for numerical simulation of knit based morphable structures: knitmorphs.

Scientific reports
Shape morphing behavior has applications in many fields such as soft robotics, actuators and sensors, solar cells, tight packaging, flexible electronics, and biomedicine. The most common approach to achieve shape morphing structures is through shape ...

Parallel transmission in a synthetic nerve.

Nature chemistry
Bioelectronic devices that are tetherless and soft are promising developments in medicine, robotics and chemical computing. Here, we describe bioinspired synthetic neurons, composed entirely of soft, flexible biomaterials, capable of rapid electroche...

Programmable Morphing Hydrogels for Soft Actuators and Robots: From Structure Designs to Active Functions.

Accounts of chemical research
Nature provides abundant inspiration and elegant paradigms for the development of smart materials that can actuate, morph, and move on demand. One remarkable capacity of living organisms is to adapt their shapes or positions in response to stimuli. P...

Acquiring structural and mechanical information of a fibrous network through deep learning.

Nanoscale
Fibrous networks play an essential role in the structure and properties of a variety of biological and engineered materials, such as cytoskeletons, protein filament-based hydrogels, and entangled or crosslinked polymer chains. Therefore, insight into...
