Effective June 2006, oil companies began distributing low sulfur diesel fuel to meet the U.S. Environmental Protection Agency's (EPA) requirement for diesel fuel for on-road motor vehicles. The new fuel's sulfur content decreased from 500 ppm to 15 ppm. This change in material composition certainly justifies reevaluating the elastomer products used in these vehicles. In addition, other EPA regulations for truck engines have resulted in an operating temperature increase of almost 50F. The combination concerned engineers at Ashtabula Rubber who investigated alternate formulas for automotive customers. "Anytime you deal with a changing environment, it's important to understand the entire application as well as the full scale of the changes taking place," says Aaron Hall, engineering manager, Ashtabula Rubber Co. "The more we know about the operating environment, the better we are able to find the right material and design for our customers."

There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
