Magnetic microrobot swarm enables 3D imaging of vascular networks
Angiography is a widely used medical imaging technique that allows medical researchers and doctors to capture the vascular network (i.e., blood vessels) using contrast agents, substances that enhance the visibility of specific structures inside the body when exposed...
PAWS: Four-legged robot can reproduce animal movement with fewer actuators
Many of the robotic systems developed in the past decades are inspired by four-legged (i.e., quadruped) animals, such as dogs, cheetahs and horses. By replicating the agile movements of these animals, quadruped robots could move swiftly on the ground, crossing long...
Wheel-less helical ring-based soft robot can move reliably in all directions
Over the past decades, roboticists have introduced a wide range of systems that can move in various complex environments, including different terrains, on the ground, in the air, and even in water. To safely navigate real-world dynamic environments without colliding...
Asymmetric ether solvents enhance Li-metal battery charging and stability
To fuel the future advancement of the electronics industry, engineers will need to develop batteries that can be charged quickly, have higher energy densities (i.e., can store more energy) and last longer. Among the most promising alternatives to lithium-ion (Li-ion)...
H-shaped bionic robot mimics cheetah’s sprint using electric charge
In recent years, roboticists and computer scientists have developed a wide range of systems inspired by nature, particularly by humans and animals. By reproducing animal movements and behaviors, these robots could navigate real-world environments more effectively.
Hydrophobic surface coating strategy addresses CO₂ electroreduction stability challenges
The conversion of carbon dioxide (CO2) into valuable chemical products via the electrochemical CO2 conversion reaction could be highly advantageous. This conversion process could help to make good use of excess CO2 in the air collected by carbon capture...
