SENSORS:Kavlico recently introduced a rugged, aerospace-grade differential pressure (DP) sensor for monitoring pressure drop across a turbine engine style inlet air filter, also known as an inlet barrier filter. The DP sensor monitors filter health by detecting increases in pressure across the filter element. The DP sensor incorporates a piezo-resistive sense element and is available in pressure ranges of 0-1, ±1, ±5 and ±10 PSID, with other options available. Other features include an operating temperature range of -40 to 125C with a storage temperature of -55 to 150C, an accuracy of ±1.5 percent of full scale over the operating temperature and an operating voltage of 5 to 15V dc. The lightweight device (<6.5 oz) is rugged by design and has a housing constructed of an anodized aluminum with an MTBF of 300,000 hours at normal operating temperature. The DP sensor typically provides an output of 50 mV at 10V dc excitation.
The 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
