Not an aging rock star, "rod creep" is a fault in a fly-fishing cast where the rod rotates forward at the end of the back cast instead of stopping. Now, thanks to MEMs technology and Noel Perkins, mechanical engineering professor at the University of Michigan, anglers may have an easier time diagnosing such faults. Perkins wanted to master fly fishing and had previous experience simulating sensor-equipped submarine detection cables for the Navy. Modeling the fly line was similar, but Perkins needed devices to help understand how much his cast deviated from ideal. Using MEMs motion sensors, he built a device to measure fly-rod motion and wired it to his Palm Pilot attached to the rod. His "casting signature" can be compared to an expert's. He is looking for partners to develop the technology. www.engin.umich.edu
The Strati EV car printed at IMTS is made of SABIC's LNP STAT KON AE003. SABIC tells Design News why this carbon fiber-reinforced compound was chosen by Local Motors and Oak Ridge National Laboratories.
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.
