The Air Force Research Laboratory is developing a high-temperature, high-performance dielectric film for the aircraft capacitors. Capacitors are devices that store electrical charges. The new film, called Fluorene Poly Ester, is suitable for applications from -55 to 227C. Aircraft capacitors are the weakest link in an aircraft's power electronics system because of their limited operating temperature, according to Sandra Fries-Carr, one of two developers of the film at the Air Force Research Laboratory. The laboratory formed a partnership with Wright Technology Network for developing the film for capacitor manufacturers. Initial applications include military aircraft projects.

Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
