In work that combines a deep understanding of the biology of soft-bodied animals such as earthworms with advances in materials and electronic technologies, researchers from the United States and China have developed a robotic device containing a stretchable transistor that allows neurological function.

Cunjiang Yu, Bill D. Cook Associate Professor of Mechanical Engineering at the University of Houston, said the work represents a significant step toward the development of prosthetics that could directly connect with the peripheral nerves in biological tissues, offering neurological function to artificial limbs, as well as toward advances in soft neurorobots capable of thinking and making judgments. Yu is corresponding author for a paper describing the work, published in Science Advances.

He is also a principal investigator with the Texas Center for Superconductivity at the University of Houston.

Back in 2011 we looked at an array of small hexagonal plates created to serve as an electronic skin that endows robots with a sense of touch. The team responsible had placed 31 of these hexagonal “skin cells” on a small robot, but now they’ve gone a lot further, equipping a human-sized robot with 1,260 cells to create what they claim is the first autonomous humanoid robot with artificial skin covering its entire body – even the soles of its feet.

In the eight years since the original touchy-feely robot, Professor Gordon Cheng and his team at the Technical University of Munich (TUM) have refined the look of the individual sensor cells, but they still boast the same basic capabilities. They’re still hexagonal in shape, allowing them to be placed in a honeycomb arrangement, and they can still measure proximity, pressure, temperature and acceleration.

Sensitive synthetic skin enables robots to sense their own bodies and surroundings—a crucial capability if they are to be in close contact with people. Inspired by human skin, a team at the Technical University of Munich (TUM) has developed a system combining artificial skin with control algorithms and used it to create the first autonomous humanoid robot with full-body artificial skin.

The artificial skin developed by Prof. Gordon Cheng and his team consists of hexagonal cells about the size of a two-euro coin (i.e. about one inch in diameter). Each is equipped with a microprocessor and sensors to detect contact, acceleration, proximity and temperature. Such artificial skin enables robots to perceive their surroundings in much greater detail and with more sensitivity. This not only helps them to move safely. It also makes them safer when operating near people and gives them the ability to anticipate and actively avoid accidents.

An organic material that can repeatedly change shape without breaking would have many useful applications, such as artificial muscles, pumps or as a switch. Physicists at Radboud University accidentally discovered a material with that property. Their findings were published in the scientific journal Nature Communications today October 8, 2019.

“I tend to call it the ‘molecular pinball machine,’” says Theo Rasing, professor of Spectroscopy of Solids and Interfaces at Radboud University. Together with colleagues from Nijmegen and China, he demonstrates the shape-changing abilities of the material by having it fling a glass bead at high speed. In that process, the organic crystal material called 4-DBpFO delivers a force corresponding to ten thousand times its own weight.

It’s happening, folks.

Neil Harbisson has an antenna implanted in his skull that allows him to feel colour, while Moon Ribas has sensors in her feet that allow her to feel earthquakes.

He said it felt like being the first man to walk on the moon.

A first: paralyzed man uses brain signals to control a robot exoskeleton.

Doctors who conducted the trial said though the device was years away from being publicly available, it had the potential to improve patients’ quality of life and autonomy.

The patient, identified only as Thibault, 28, from Lyon, said the technology had given him a new lease of life. Four years ago his life was permanently changed when he fell 40ft (12 metres) from a balcony, severing his spinal cord and leaving him paralysed from the shoulders down.
