Engineers 3-D print flexible mesh for ankle and knee braces
Hearing aids, dental crowns, and limb prosthetics are some of the medical devices that can now be digitally designed and customized for individual patients, thanks to 3-D printing. However, these devices are typically designed to replace or support bones and other rigid parts of the body, and are often printed from solid, relatively inflexible material.
Cytophone detects melanoma in earliest stages
A research team has demonstrated the ability to detect and kill circulating tumor cells in the blood using a noninvasive device called Cytophone that integrates a laser, ultrasound and phone technologies.
Algorithm tells robots where nearby humans are headed
A new tool for predicting a person's movement trajectory may help humans and robots work together in close proximity.
Selenium improves thin film solar cells
The rows of blue solar panels that dot landscapes and rooftops are typically made out of crystalline silicon, the workhorse semiconductor found in virtually every electronic device.
Low-cost, high-tech synthetic biology for the classroom
How can high school students learn about a technology as complex and abstract as CRISPR? It's simple: just add water.
Hummingbird robot uses AI to soon go where drones can't
Researchers have engineered flying robots that behave like hummingbirds, trained by machine learning algorithms based on various techniques the bird uses naturally every day.
Snake-inspired robot slithers even better
Bad news for ophiophobes: Researchers have developed a new and improved snake-inspired soft robot that is faster and more precise than its predecessor.
Robots that can sort recycling
Every year trash companies sift through an estimated 68 million tons of recycling, which is the weight equivalent of more than 30 million cars.
New approach could boost energy capacity of lithium batteries
Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today's versions, potentially enabling electric cars to travel further or portable electronics to run for longer without recharging.
3D printed tissues may keep athletes in action
Bioscientists are moving closer to 3D-printed artificial tissues to help heal bone and cartilage typically damaged in sports-related injuries to knees, ankles and elbows.
New 3-D printing approach makes cell-scale lattice structures
A new way of making scaffolding for biological cultures could make it possible to grow cells that are highly uniform in shape and size, and potentially with certain functions. The new approach uses an extremely fine-scale form of 3-D printing, using an electric field to draw fibers one-tenth the width of a human hair.
Spider silk could be used as robotic muscle
Spider silk, already known as one of the strongest materials for its weight, turns out to have another unusual property that might lead to new kinds of artificial muscles or robotic actuators, researchers have found.
Charting a path to cheaper flexible solar cells
There's a lot to like about perovskite-based solar cells. They are simple and cheap to produce, offer flexibility that could unlock a wide new range of installation methods and places, and in recent years have reached energy efficiencies approaching those of traditional silicon-based cells. But figuring out how to produce perovskite-based energy devices that last longer than a couple of months has been a challenge.
Unleashing perovskites' potential for solar cells
Researchers have been able to decipher a key aspect of the behavior of perovskites made with different formulations: With certain additives there is a kind of "sweet spot" where greater amounts will enhance performance and beyond which further amounts begin to degrade it.
Converting Wi-Fi signals to electricity with new 2-D materials
Imagine a world where smartphones, laptops, wearables, and other electronics are powered without batteries. Researchers from MIT and elsewhere have taken a step in that direction, with the first fully flexible device that can convert energy from Wi-Fi signals into electricity that could power electronics.
Sodium ion battery research could power up renewable energy storage
Longer life and increased capacity for a new technology battery that could be the workhorse of a renewable energy grid are the goals of a study of the effect of charging cycles on the structure of anodes in sodium ion batteries.
IDTechEx analyst Nadia Tsao interviewed AxoSim Technologies CEO Dr Lowry Curley and Director of Business & Partnership Development Ben Cappiello. AxoSim provides a nerve-on-a-chip platform for drug development.
Foldable drone flies through narrow holes
A research team have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Manganese may finally solve hydrogen fuel cells' catalyst problem
Manganese is known for making stainless steel and aluminum soda cans. Now, researchers say the metal could advance one of the most promising sources of renewable energy: hydrogen fuel cells.
