Options for Monitoring Humidity Inside Sealed Enclosures
Opening a sealed enclosure to check for moisture can introduce the very humidity you're trying to control. Humidity indicators and monitoring devices give engineers a way to evaluate conditions inside an enclosure without disrupting the protected environment.
  • Monitor relative humidity without opening the enclosure
  • Identify when moisture levels begin to rise
  • Help determine when desiccant may need attention or replacement
  • Choose from visual indicators or electronic monitoring options
Learn how humidity indicators and sensors work.

Military: UK trying ground-launched paraglider tech for covert ops
British commandos could soon be equipped with portable powered paragliders for covert missions in hostile territory, thanks to a UK Ministry of Defence-funded invention by a UK startup. Unassembled, the paragliders fit in a rucksack-sized case. Soldiers could quickly assemble and then fly the machines -- complete with weapon mounts -- up to 200 miles for covert ops.

Your smartwatch is lying to you about how many calories you burned in your last workout
If you are depending on your smartwatch to tell you the truth about how many calories you burned during a workout -- well, don't. Researchers at Florida International University tested popular smartwatches -- including Apple, Garmin, Samsung, and Fitbit -- and found they all overestimated calories burned. Here's how to still get value from yours.

Metal foam could make cars safer in collisions
A new study finds that composite metal foam could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into automobile "front rails" would allow them to absorb more energy during high-velocity impacts.

Superheated steam bests hot air for energy-efficient industrial drying
Industrial drying processes consume large amounts of energy burning fossil fuels to heat air. Researchers at Fraunhofer IGB are working with industry partners on a new approach using superheated steam. Combined with a heat pump and smart controls, this new process saves significant amounts of energy and eliminates the need for natural gas.

Image - Tech Tip: Fan selection - Why airflow is not just CFM
Tech Tip: Fan selection - Why airflow is not just CFM
For many engineers, fan selection starts and ends with a single number: CFM (cubic feet per minute). Higher CFM feels like a clear win. More air moved must mean better cooling. However, in practice, this assumption is one of the most common causes of thermal problems, excess noise, and late-stage redesigns. Find out why.
