(via sciencedaily.com) Original source A new patch uses tiny needles to measure electrical signals in the human body with incredible accuracy, even when these devices are stretched or twisted.
Published Artificial muscles -- lighter, safer, more robust
(via sciencedaily.com) Original source Researchers have developed artificial muscles that are lighter, safer and more robust than their predecessors. The newly developed actuators have a novel type of shell structure and use a high-permittivity ferroelectric material that can store relatively large amounts of electrical energy. They therefore work with relatively low electrical voltage, are waterproof, more robust and safer to touch.

Published Researchers propose AI-guided system for robotic inspection of buildings, roads and bridges
(via sciencedaily.com) Original source Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.
Published Robot trained to read braille at twice the speed of humans
(via sciencedaily.com) Original source Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers.
Published Utilizing active microparticles for artificial intelligence
(via sciencedaily.com) Original source Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists have now created a type of neural network that works not with electricity but with so-called active colloidal particles.The researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series.
Published Scientists design a two-legged robot powered by muscle tissue
(via sciencedaily.com) Original source Compared to robots, human bodies are flexible, capable of fine movements, and can convert energy efficiently into movement. Drawing inspiration from human gait, researchers from Japan crafted a two-legged biohybrid robot by combining muscle tissues and artificial materials. This method allows the robot to walk and pivot.
Published Autonomous synthesis robot uses AI to speed up chemical discovery
(via sciencedaily.com) Original source Chemists have developed an autonomous chemical synthesis robot with an integrated AI-driven machine learning unit. Dubbed 'RoboChem', the benchtop device can outperform a human chemist in terms of speed and accuracy while also displaying a high level of ingenuity. As the first of its kind, it could significantly accelerate chemical discovery of molecules for pharmaceutical and many other applications.
Published Mini-robots modeled on insects may be smallest, lightest, fastest ever developed
(via sciencedaily.com) Original source Two insect-like robots, a mini-bug and a water strider may be the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second.
Published New technology for conducting deep-sea research on fragile organisms
(via sciencedaily.com) Original source Scientists have successfully demonstrated new technologies that can obtain preserved tissue and high-resolution 3D images within minutes of encountering some of the most fragile animals in the deep ocean.
Published 'Smart glove' can boost hand mobility of stroke patients
(via sciencedaily.com) Original source This month, a group of stroke survivors in British Columbia will test a new technology designed to aid their recovery, and ultimately restore use of their limbs and hands. Participants will wear a new groundbreaking 'smart glove' capable of tracking their hand and finger movements during rehabilitation exercises.
Published Squishy, metal-free magnets to power robots and guide medical implants
(via sciencedaily.com) Original source 'Soft robots,' medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism -- thanks to a metal-free magnetic gel developed by researchers. Carbon-based, magnetic molecules are chemically bonded to the molecular network of a gel, creating a flexible, long-lived magnet for soft robotics.
Published Artificial muscle device produces force 34 times its weight
(via sciencedaily.com) Original source Scientists developed a soft fluidic switch using an ionic polymer artificial muscle that runs with ultra-low power to lift objects 34 times greater than its weight. Its light weight and small size make it applicable to various industrial fields such as soft electronics, smart textiles, and biomedical devices by controlling fluid flow with high precision, even in narrow spaces.
