Robot face with lab-grown living skin created by scientists hoping to make more human-like cyborgs

This fleshy, pink smiling face is made from living human skin cells, and was created as part of an experiment to let robots show emotion.

How would such a living tissue surface, whatever its advantages and disadvantages, attach to the mechanical foundation of a robot’s limb or “face”?

In humans and…


A team of scientists unveiled a robot face covered with a delicate layer of living skin that heals itself and crinkles into a smile in hopes of developing more human-like cyborgs.

The skin was made in a lab at the University of Tokyo from a mixture of human skin cells grown on a collagen model and placed on top of a 3D-printed resin base, the New Scientist reported.

Scientists on the project — who published their findings in Cell Reports Physical Science on Tuesday — believe the living skin could be a key step in creating robots that heal and feel like humans.

AI improves human locomotion in robotic exoskeletons, saves 25% energy

The exoskeleton is being developed for older adults and people with conditions like cerebral palsy:


A new method developed by researchers uses AI and computer simulations to train robotic exoskeletons to autonomously help users save energy.

Researchers from North Carolina State University, in their new study, showed the technologically advanced instrument as an achievement in reinforcement learning, a technique that trains software to make decisions.

In a demonstration video, provided as part of their new research published in Nature, the method consists of taping into three neural networks: motion imitation, muscle coordination, and exoskeleton control networks.

AI strategy may promise more widespread use of portable, robotic exoskeletons—on Earth and in space

Exoskeleton for real world adoption.

A super smart or “learned” controller that leverages data-intensive artificial intelligence (AI) and computer simulations to train portable, robotic exoskeletons.

This new controller provides smooth, continuous torque assistance for walking, running, or climbing…


Safer, more efficient movements for factory workers and astronauts, and improved mobility for people with disabilities could someday become a more widespread reality, thanks to research published June 12 in the journal Nature.

Cambridge Scientists Develop “Third Thumb” That Could Redefine Human Capability

Researchers at Cambridge have shown that the Third Thumb, a robotic prosthetic, can be quickly mastered by the public, enhancing manual dexterity. The study stresses the importance of inclusive design to ensure technologies benefit everyone, with significant findings on performance across different demographics.

Cambridge researchers demonstrated that people can rapidly learn to control a prosthetic extra thumb, known as a “third thumb,” and use it effectively to grasp and handle objects.

The team tested the robotic device on a diverse range of participants, which they say is essential for ensuring new technologies are inclusive and can work for everyone.

Living brain-cell biocomputers are now training on dopamine

Current AI training methods burn colossal amounts of energy to learn, but the human brain sips just 20 W. Swiss startup FinalSpark is now selling access to cyborg biocomputers, running up to four living human brain organoids wired into silicon chips.

The human brain communicates within itself and with the rest of the body mainly through electrical signals; sights, sounds and sensations are all converted into electrical pulses before our brains can perceive them. This makes brain tissue highly compatible with silicon chips, at least for as long as you can keep it alive.

For FinalSpark’s Neuroplatform, brain organoids comprising about 10,000 living neurons are grown from stem cells. These little balls, about 0.5 mm (0.02 in) in diameter, are kept in incubators at around body temperature, supplied with water and nutrients and protected from bacterial or viral contamination, and they’re wired into an electrical circuit with a series of tiny electrodes.

Intelligent Neuroprostheses: Brain-Controlled Devices Mimic Natural Motor Control

Researchers have tested a range of neuroprosthetic devices, from wheelchairs to robots to advanced limbs, that work with their users to intelligently perform tasks.

They work by decoding brain signals to determine the actions their users want to take, and then use advanced robotics to do the work of the spinal cord in orchestrating the movements. The use of shared control — new to neuroprostheses — “empowers users to perform complex tasks,” says José del R. Millán, who presented the new work at the Cognitive Neuroscience Society (CNS) conference in San Francisco today.

Millán, of the Swiss Federal Institute of Technology in Lausanne, Switzerland, began working on “brain-computer interfaces” (BCIs), designing devices that use people’s own brain activity to restore hand grasping and locomotion, or provide mobility via wheelchairs or telepresence robots, using people’s own brain activity.

Imperceptible sensors made from ‘electronic spider silk’ can be printed directly on human skin

While wearable technologies with embedded sensors, such as smartwatches, are widely available, these devices can be uncomfortable, obtrusive and can inhibit the skin’s intrinsic sensations.

“If you want to accurately sense anything on a biological surface like skin or a leaf, the interface between the device and the surface is vital,” said Professor Yan Yan Shery Huang from Cambridge’s Department of Engineering, who led the research. “We also want bioelectronics that are completely imperceptible to the user, so they don’t in any way interfere with how the user interacts with the world, and we want them to be sustainable and low waste.”

There are multiple methods for making wearable sensors, but these all have drawbacks. Flexible electronics, for example, are normally printed on plastic films that don’t allow gas or moisture to pass through, so it would be like wrapping your skin in plastic film. Other researchers have recently developed flexible electronics that are gas-permeable, like artificial skins, but these still interfere with normal sensation, and rely on energy-and waste-intensive manufacturing techniques.
