Super Sensitive Electronic Skin for Prosthetic Devices

Artificial skin with the ability to feel is a major research goal for engineers working on improving prosthetic technology. Researchers in the past have created materials with sensors spread over a few square inches, but these have typically had a number of limitations. One thing that causes many such electronic skins to be impractical is [… (Read more...)

Artificial Muscle Fibers for Biomedical Applications

Scientists at MIT have taken inspiration from cucumber tendrils, the helical offshoots that grab onto fences and anything else they can, to create artificial muscle-like fibers. The new fibers can quickly contract and expand, and can lift objects many times their weight. The hope is that these may one day find their way into medical […]

Printing Skin, Bones for Surgeries on Way to Mars

Traveling to Mars, our closest planet and which may one day serve as another base for humanity, is very far away. Any practical mission there and back will take years. The health of the astronauts undertaking such a journey will be paramount, so researchers are working on ways to be able to create customized tissues […]

Microfluidic Chip Allows Embryonic Stem Cells to Differentiate

Complex multicellular organisms, such as ourselves, start out from stem cells that differentiate into different kinds of cells. This process is controlled by groups of cells that secrete special signaling molecules called morphogens, which guide nearby stem cells to turn into the kinds of cells that should be located in that region. This is an [&he (Read more...)

Severely Disabled People Mind-Control a Robotic Arm via EEG

Scientific collaborators from Carnegie Mellon University and University of Minnesota have created a way for people to control a robotic arm using a non-invasive brain-computer interface (BCI). Previously, electrode array implants in the brain have been necessary to give severely disabled people the ability to manipulate an external robot. That is b (Read more...)

Researchers Trip People to Improve Prosthetic Legs

People using prosthetic legs have to be constantly vigilant about potential obstacles in their way. That is because if they stumble, there’s a pretty good chance that they’ll suffer a fall. Prosthetic legs, even powered ones, don’t have the capacity to recover from a stumble, as this is a very challenging task for a mechanical [&h (Read more...)

Electric Brain Stimulation Shown to Improve Memory Function

Our memories often seem ephemeral, coming and going without any obvious reasons. Researchers at UCLA seem to have come up with a way to bring some memories back that would probably otherwise have gone missing forever. The team relied on transcranial direct current stimulation (tDCS), a technology that can direct low energy electricity into specific (Read more...)

Octopus-Inspired Wearable Biosensor Sticks to Wet and Dry Skin

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a new waterproof, wearable biosensor that can stick to the skin in a unique way. Their work, recently published in ACS Applied Materials and Interfaces, demonstrates the biosensor adheres to the skin in wet and dry conditions and can monitor [ (Read more...)

Study of People with Extra Fingers Points to New Approaches for Development of Prosthetic Devices

Kids with extra fingers on their hands usually have them removed soon after birth, but some get to keep them into adulthood. This condition, known as polydactyly, is usually looked upon as a disability that has to be studied and addressed. Researchers at the University of Freiburg in Germany, Imperial College London, and the Université [&hel (Read more...)

Patches Made of Heart Tissue Going to Clinical Trials

Stem cell therapies to heal damaged hearts have proven to be lacking so far, probably because simply injecting new cells into afflicted regions isn’t enough. Researchers from Imperial College London have now created patches made of cardiac tissue to sew over damaged areas of the heart. These patches, which can beat on their own to […]

Tripod Prosthetic Foot for More Stability on Rough Terrain

Researchers at Stanford have developed an unusual tripod-like prosthetic foot equipped with sensors to monitor movement and the surrounding environment. The device provides more stability for users when walking on rough terrain. The research team designed the prototype device using a prosthetic emulation system that allowed them to rapidly modify a (Read more...)

Smart Glove for Prostheses Identifies Objects in Hand

One thing that prosthetic device users hope for is to gain the ability to feel what they’re touching with their hands. There have been some developments in this space (see flashbacks below), but they’re still relatively rudimentary, not very sensitive, and not very good at helping users to identify what it is that they’re touching (Read more...)
