Sensors are used by engineers to characterize the characteristics or behavior of an object or system. Choosing the right sensor for the job is critical. more...
Introduction to Optical Sensors
Optical sensors detect the presence or behavior of light waves. This could include light in the visible spectrum, or outside the visible spectrum. more...
An Introduction to Accelerometers
Accelerometers allow engineers to measure the accelerations in bodies and systems to ensure safety and proper operation, but can also be found in everyday objects. more...
Non-Destructive Evaluation Methods
Non-destructive evaluation methods allow for inspection and characterization of complex systems to find flaws before they become critical. more...
Chemical engineers are involved in pharmaceuticals, fossil and biofuels, materials and processes related to many household products. more...
Electrical and mechanical sensors are widely used to characterize the performance and properties of components and systems, but are also found in household objects. more...
National Engineers Week occurs in February each year, and is held to create awareness of the contributions of engineers to society. more...

An Introduction to Solar Energy
Solar power is the ultimate renewable energy source. Here is an introduction to the basic science that makes all solar energy technologies possible. more...
An Introduction to Tin Whiskers
Tin whiskers are mysterious, hair-like metal crystals that sprout from circuit boards and hardware, causing shorts and power failures in critical electronic systems. more...
Non-Defense Nuclear Technologies
Nuclear radiation has great potential for destruction. But engineers and scientists have harnessed the power of atomic forces for a wide range of uses to help humanity. more...
Nuclear Radiation Detectors 101
How do radiation detectors work? And how does Homeland Security use them at the borders to prevent nuclear materials from being used in weapons of mass destruction? more...
Nuclear power plants provide about one-fifth of the world's electricity. How do they work? And why do they produce radioactive waste that will remain toxic for centuries? more...
An Introduction to RFID Technology
RFID is not a new technology but it is being used in new ways. RFID tags keep track of things using tiny electronic circuits that can be "read" by a special receiver. more...
Research to Expand Biofuel Sources
Ethanol made from corn is already helping to reduce CO2 emissions and increase national security, by providing a renewable alternative fuel to the U.S. energy portfolio. more...
