New Way To Make Sheets Of Graphene Discovered
Posted in News, Electronic Components, Solar Power, Coatings & Adhesives on Tuesday, 10 June 2014
Graphene's promise as a material for new kinds of electronic devices, among other uses, has led researchers around the world to study the material in search of new applications. But one of the biggest limitations to wider use of the strong, lightweight, highly conductive material has been the hurdle of fabrication on an industrial scale.

Researchers at the National Institute of Standards and Technology (NIST), Gaithersburg, MD, say that they have built and demonstrated a chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging. The new microfluidic chip produces polarized (or magnetized) xenon gas and then detects even the faintest magnetic signals from the gas.
New Algorithms Enable Self-Assembling, Printable Robots

In two new papers, MIT researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed three-dimensional configurations.

One paper describes a system that takes a digital specification of a 3-D shape — such as a computer-aided design, or CAD, file — and generates the 2-D patterns that would enable a piece of plastic to reproduce it through self-folding.

The other paper explains how to build electrical components from self-folding laser-cut materials. The researchers present designs for resistors, inductors, and capacitors, as well as sensors and actuators — the electromechanical “muscles” that enable robots’ movements.

“We have this big dream of the hardware compiler, where you can specify, ‘I want a robot that will play with my cat,’ or ‘I want a robot that will clean the floor,’ and from this high-level specification, you actually generate a working device,” said Daniela Rus, the Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT.

New Rotary Sensor Keeps Conveyor Belts Running Smoothly
Posted in News, Electronic Components, Consumer Product Manufacturing, Industrial Controls & Automation, Optics, Photonics, Sensors, Measuring Instruments on Wednesday, 28 May 2014
Rotary sensors can help determine the position of a moveable body in relation to an axis. They are essential to the smooth running of car engines in the automotive industry, for example. In factories, goods and products are transported from one processing station to the next via conveyor belt. For the transfer from one belt to the next to run smoothly, it must take place precisely at a specific position, which means knowing the relative position of objects on the conveyor belts as they move towards each other. This can be determined from the angle of rotation, which refers to the position of a moveable body to an axis.
Wireless System Paves Way for 'Electroceutical' Medical Devices
Posted in News, Wireless, Electronic Components, Power Management, Drug Delivery & Fluid Handling, Implants & Prosthetics, Patient Monitoring on Tuesday, 27 May 2014
A wireless system uses the same power as a cell phone to safely transmit energy to chips the size of a grain of rice. The technology paves the way for new "electroceutical" devices to treat illness or alleviate pain.

The central discovery is an engineering breakthrough that creates a new type of wireless power transfer that can safely penetrate deep inside the body.

The technology could spawn a new generation of programmable microimplants – sensors to monitor vital functions deep inside the body; electrostimulators to change neural signals in the brain; and drug delivery systems to apply medicines directly to affected areas.
