To support an Oak Ridge National Laboratory programs exoskeleton project, a unique multi-axis foot force/torque sensor was constructed and tested that has biomedical application such as clinical gait analysis. The challenging aspect of this multi-axis force sensor is that it had to conform to the bending of the human foot, withstand high impact loads, have high force sensitivity, feel comfortable to the human wearer, be integrated into a military style boot, measure the forces on the human foot when either the ball or the heel of the foot is in contact with the ground, respond to both positive and negative loading and have a low overall height and weight. This paper describes the design and testing of this unique sensor.

Lockheed Martin and Oak Ridge National Laboratory (ORNL) are working on an additive manufacturing (AM) system (Big Area Additive Manufacturing, or BAAM) capable of producing components measured not in terms of inches or feet, but multiple yards in all dimensions. The highly automated system has the potential to manufacture parts completely unbounded in size.

The term transnationalism is used frequently in reference to the rapid circulation of “capital, labor, technology, and media images” in the global economy governed by postindustrial capitalism (Sharpe 110). When incorporated into such phrases as transnational capitalism, the term implies a critical view of historically specific late modern or postmodern practices of globalizing production, marketing, distribution, and consumption for neocolonial ends. By the same token, transnationalism is often used to suggest counterhegemonic practices prompted by or accompanying the migrations and diasporas occasioned by these new economic processes of globalization. Thus, Homi Bhabha's privileging of “cultural hybridity” as a way to resist global homogenization is often traceable to his emphasis on “migrant workers,” who are “part of the massive economic and political diaspora of the modern world” and thus “embody […] that moment blasted out of the continuum of history” (8). If these new, exploited cosmopolitans experience every day their dislocation from the familiar boundaries of nation, first language, and citizenship, they may also be particularly able to comprehend how to negotiate transnational situations, even in some cases turning such circumstances to their advantage.
