Scientists cover robotic finger with living skin made from human cells
We’ve been hearing a lot about synthetic skins designed for robotic hands, which would give the devices more human-like qualities. Well, scientists in Japan have gone a step further, by covering a robotic finger in a self-healing skin made from live human cells.
Led by Prof. Shoji Takeuchi, a team at the University of Tokyo started by building an articulated motor-driven robotic finger, capable of bending and straightening like its human counterpart. That finger was then submerged in a cylinder filled with a solution made up of collagen and human dermal fibroblast cells – these are the main components of our skin’s connective tissues.
Due to its natural properties, that solution shrank and conformed to the contours of the finger, forming a seamless hydrogel coating. Next, the scientists added a layer of human epidermal keratinocyte cells, which constitute 90 percent of our epidermis (the outermost layer of skin). These formed a moisture-retaining/water-resistant barrier on top of the gel, and gave the finger a more natural texture.

Numerous activities, including construction and demolition, mining and industrial activities, cooking and gardening, and others, generate a substantial amount of garbage. The amount of waste generated is directly proportional to consumption and production patterns.
In most cases, waste formation is the result of inefficient material utilization. Trends in the number, composition and impacts of these materials provide insight into the nation’s efficiency in using (and reusing) materials and resources. It also provides a better understanding of the effects of waste on human health and the environment.
According to surveys, 92 million tonnes of cloth are dumped as garbage each year worldwide. Estimates predict that this figure will likely exceed 130 million tonnes by 2030. When 200 tonnes of water used to make a single tonne of fabric is considered, it becomes clear that the end-to-end processes of the garment industry are severe threats to environmental initiatives.
Scientists grew living human skin around a robotic finger
In the hopes of one day building super realistic cyborgs, researchers built a robotic finger that wears living human skin.

Training a robot to recognize and pour water

A horse, a zebra and artificial intelligence helped a team of Carnegie Mellon University researchers teach a robot to recognize water and pour it into a glass.
Water presents a tricky challenge for robots because it is clear. Robots have learned how to pour water before, but previous techniques like heating the water and using a thermal camera or placing the glass in front of a checkerboard background don’t transition well to everyday life. An easier solution could enable robot servers to refill water glasses, robot pharmacists to measure and mix medicines, or robot gardeners to water plants.
Wearable, waterproof sensors combine high sensitivity and location options
Wearable sensors—an important tool for health monitoring and for training artificial intelligence—can be waterproof or can measure more than one stimuli, but combining these factors while maintaining a high level of precision in the measurements is difficult. Researchers co-led by Huanyu “Larry” Cheng, assistant professor of engineering science and mechanics at Penn State, have created sensors that are waterproof, an important trait for exercise monitoring and for withstanding perspiration and all weather conditions; can measure temperature and motion on both small and large scales; and can be attached to distal arteries such as those located beneath the eyebrow or in a toe.
The results are available now online in the Chemical Engineering Journal ahead of publication in the journal’s September print edition.
“There are three aspects of this that are novel in combination: the underwater application, the ability to detect ultra-small vibrations and subtle motions and temperature changes, and the multiple options for sensor location, such as the eyebrow or toe,” Cheng said.
Biomimetic elastomeric robot skin has tactile sensing abilities
A team of researchers at Korea Advanced Institute of Science and Technology, working with one colleague from MIT and another from the University of Stuttgart, has developed a biomimetic elastomeric robot skin that has tactile sensing abilities. Their work has been published in the journal Science Robotics.
Roboticists continue to work on improving robot abilities and to make them more human-like. In this new effort, the researchers gave a robot arm the ability to detect such sensations as a pat, tickling, wind, or something stroking its surface. They accomplished this by partially imitating human skin.
The new robot skin is multi-layered, like human skin, to allow for different functions. The top layer is made of a rubber-like polymer resembling human skin. Beneath that, the researchers added a hydrogel to imitate the human epidermis. They chose a hydrogel because it not only deforms when pressed, but jiggles when bumped. By embedding sensors to detect these reactions, the skin is able to sense things like a finger press by monitoring the pressure of the hydrogel and the direction of its movement. If something taps against it, the system senses and measures ripples in the hydrogel to gauge what the tap felt like.
