Artificial muscles give soft robots superpowers

Mon, 27 Nov 2017 15:00:07 EST

Soft robotics has made leaps and bounds over the last decade as researchers around the world have experimented with different materials and designs to allow once rigid, jerky machines to bend and flex in ways that mimic and can interact more naturally with living organisms. However, increased flexibility and dexterity has a trade-off of reduced strength, as softer materials are generally not as strong or resilient as inflexible ones, which limits their use.



Old, meet new: Drones, high-tech camera revamp archaeology

Fri, 24 Nov 2017 10:34:41 EST

Scanning an empty field that once housed a Shaker village in New Hampshire, Jesse Casana had come in search of the foundations of stone buildings, long-forgotten roadways and other remnants of this community dating to the 1790s.



New method analyzes corn kernel characteristics

Fri, 17 Nov 2017 02:17:51 EST

An ear of corn averages about 800 kernels. A traditional field method to estimate the number of kernels on the ear is to manually count the number of rows and multiply by the number of kernels in one length of the ear. With the help of a new imaging machine developed at the University of Illinois breeders can learn the number of kernels per ear, plus a lot more information than can be manually observed.



Optically tunable microwave antennas for 5G applications

Thu, 16 Nov 2017 07:40:03 EST

Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas in silicon to tune both radiation patterns and operation frequency.



Research could 'untangle' vexing problem in computer-simulation technology

Wed, 08 Nov 2017 11:50:32 EST

The computer simulations used to design, optimize, test or control a vast range of objects and products in our daily lives are underpinned by finite element methods.



Fully integrated circuits printed directly onto fabric

Wed, 08 Nov 2017 08:41:33 EST

Researchers have successfully incorporated washable, stretchable and breathable electronic circuits into fabric, opening up new possibilities for smart textiles and wearable electronics.

Fluidic transistor ushers the age of liquid computers

Fri, 03 Nov 2017 16:12:19 EST

Transistors, those tiny electrical switches that process signals and data, are the brain power behind every electronic device – from laptops and smartphones to your digital thermostat. As they continue to shrink in size, computers have become smaller, more powerful, and more pervasive. However, as we look to build squishy, human-friendly machines that have the look and feel of soft natural organisms, we need to look beyond the rigid materials used to create electrical switches and circuits.
