3D-Printed Soft Robot ‘Walks’ on Any Terrain

Traditional robots often feature isolated mechanical joints. These discrete components limit a rover’s ability to traverse sand, stone, and other challenging environments.

A team at the University of California San Diego has demonstrated a more flexible option: a soft robot that lifts its legs over obstacles and operates on a variety of terrains. The 3D-printed quadrupedal technology may someday support search-and-rescue missions requiring intelligent navigation capabilities.

Non-Toxic Material Generates Electricity Through Heat, Cold Air

Imagine a body sensor powered by one's jewelry, or a cooking pan that charges a cell phone in a few hours.

Using a combination of the chemical elements calcium, cobalt, and terbium, University of Utah researchers created an efficient, inexpensive and bio-friendly material that generates electricity through a thermoelectric process involving heat and cold air.

Researchers Craft New Material That Could Improve LED Screens

Researchers working at the Ultrafast Laser Lab at the University of Kansas successfully created a new bilayer material, with each layer measuring less than one nanometer in thickness. The new material, that someday could lead to more efficient and versatile light emission, was made by combining atomically thin layers of molybdenum disulfide and rhenium disulfide.

Researchers Find 'Golden' Idea for New Wearables

Researchers at Missouri University of Science and Technology have developed a way to “grow” thin layers of gold on single crystal wafers of silicon, remove the gold foils, and use them as substrates on which to grow other electronic materials. The discovery could lead to new wearable developments, including a smartphone that conforms entirely to one's wrist.

'Tougher-than-Metal' Hydrogels Support New Biomaterials

Scientists from Japan's Hokkaido University have created tough hydrogels combined with woven fiber fabric. The "fiber-reinforced soft composite" fabrics are highly flexible, stronger than metals, and can support a number of potential applications, including artificial ligaments and tendons subjected to load-bearing tension.

Engineers and scientists at the University of Texas at Austin and the AMOLF institute in the Netherlands have invented mechanical metamaterials that transfer motion in one direction while blocking it in the other. The material can be thought of as a mechanical one-way shield that blocks energy from coming in but easily transmits it going out the other side. The researchers developed the mechanical materials using metamaterials, which are synthetic materials with properties that cannot be found in nature.

Light-Absorbent Material Keeps Buildings Cool

Engineers at the University of California San Diego have created a thin, flexible, light-absorbing material that absorbs more than 87 percent of near-infrared light. The technology could someday support the development of solar cells; transparent window coatings to keep cars and buildings cool; and lightweight shields that block thermal detection.

Researchers Awaken Graphene's Hidden Superconductivity

Since its discovery in 2004, scientists have believed that graphene contained an innate ability to superconduct. Now researchers from the University of Cambridge have found a way to activate that previously dormant potential, enabling the material to carry an electrical current with zero resistance.
