High-Res Line Camera Measures Magnetic Fields in Real Time

Scientists have developed a high‑resolution magnetic line camera to measure magnetic fields in real time. Field lines in magnetic systems such as generators or motors that are invisible to the human eye can be made visible using this camera. It is especially suitable for industrial applications in quality assurance during the manufacture of magnets.

Sensors Monitor Dangerous Hits on the Football Field

In football, a tackle can supply 100 Gs of force or more, well above the amount that can cause a concussion and more than 10 times the force of an F‑16 jet roll maneuver. University of Florida (UF) researchers are using the helmets of Gator football players to help measure the force of on‑field hits to better understand and prevent concussions, and treat them before they cause lasting damage.

Analog Signal Conditioning for Accurate Measurements

By Jon Titus Q: Should I put some sort of circuit between my sensor and an analog-to-digital converter? A:Yes. You probably need some signal conditioning. The explanation below goes on for a bit, but stay with it and you'll understand what you need and why you need it. Before you make any connections, get the electrical specifications for the analog-to-digital converter (ADC) and for the sensor or sensors in your system. Let's assume the data-acquisition module uses a Maxim Integrated Products MAX197 12-bit ADC. This device can accept eight differential (2-wire) inputs or 16 single-ended (1-wire) inputs. Maxim's specifications show an input impedance of 21 kohms for single-ended inputs and 16 kohms for differential inputs.

Space-Based Instrument Monitors Plant Health

A new space‑based instrument to study how effectively plants use water is being developed at NASA's Jet Propulsion Laboratory. The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) will monitor one of the most basic processes in living plants: the loss of water through the tiny pores in leaves, or transpiration. ECOSTRESS will measure combined evaporation and transpiration, known as evapotranspiration, from the International Space Station.

Will "4D" materials catch on?

This week's Question: While 3D printing has still not yet reached the mainstream, MIT and other researchers are performing primary tests on the next design dimension. 4D printing, a self-assembly design process, enables the production of composite materials that react and change shape in predictable ways when exposed to external elements such as water. A printed rear wing, for example, would have the ability to transform its aerodynamics during a downpour. Autonomous pipes, too, could expand and narrow based on flow. Self-assembling technologies may eventually allow the construction of space structures whose components deposit themselves in zero-gravity environments without human intervention. Wood and carbon fibers have responded well to 4D testing, but more materials and energy sources are likely required for the materials to self‑optimize according to sensing and logic. What do you think? Will "4D" materials catch on?
