Metastable material: Study shows availability of hydrogen controls chemical structure of graphene oxideMay 22, 2012 4:50 pm | by Georgia Institute of Technology | Articles | Comments
A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy storage. The study also found that after the material is produced,
Data acquisition (DAQ) hardware serves as the interface between a computer and signals from the outside world. There are hundreds of different types of DAQ hardware with a range of sampling rates, resolutions, signal conditioning options, and form factors. Use these five questions as a guide to help you choose the right DAQ hardware for your application.
Many modern day carbon dioxide (CO2) sensing and blood alcohol detection applications utilize infrared (IR) spectroscopy technology. IR spectroscopy has increased in popularity due to its combination of exceptional accuracy, selectivity, and reliability. IR spectroscopy is based on the principle that most gas molecules absorb IR light...

Designing and implementing sensor interface designs for nonlinear, temperature-dependent transducers presents some difficult challenges. The advent of dedicated and powerful Sensor Signal Conditioning (SSC) ICs has made the job easier, but choosing the right IC for a particular sensor and application is critical for
POSITAL’s ACCELENS (ACS) inclinometers are now available in two major product lines. The first of these is designed primarily for industrial environments and features a tough fiber-reinforced PBT plastic housings and fully-encapsulated electronic components. These devices can
Although force measurement has become commonplace in most manufacturing environments, many of us may still appreciate being refreshed on its rudiments from time to time. Many who have attempted to educate themselves on this topic will tell you that the reading material can be a bit unpalatable. Because of this, we are pleased to offer an overview to force measurement
The intersection of nanopositioning and microscopy is expanding and deepening rapidly. The evolutions of disciplines as diverse as single-molecule biophysics, super-resolution microscopy and automated microassay scanning share several common themes which combine to increase the prevalence of piezo-based positioning systems added-to or integrated into microscopic setups. Recently developed mechanisms of significant relevance to microscopic applications present substantial new opportunities for advancement.
Motion is the latest trump card available to CE manufacturers, enabling the ability to create a new generation of products to operate how people naturally interact. Enabling this trend is a unique class of motion-sensing chips, referred to as MEMS (Micro-Electro-Mechanical Systems).
As applications engineers supporting ADI’s compact, low-cost, gravity-sensitive iMEMs accelerometers, we get to hear lots of creative ideas about how to employ accelerometers in useful ways; but sometimes the suggestions violate physical laws! We’ve rated some of these ideas on an informal scale, from “real” to “dream land”:
Although resistive technologies have conventionally been used to detect the position of a single touch on the screen, this article examines a new dual-touch concept that uses a resistive touch-screen controller to detect the most common two-finger gestures (zoom, pinch and rotation) using inexpensive resistive touch screens.
