Humans and other animals walk in a way that minimizes energy consumption. We take advantage of inertial passive dynamics and elastic energy storage and return to create a walking pattern that is extremely economical [1]. A reduction in energy consumption during walking might be achieved by supplying external mechanical power to the joints of the lower limbs. With additional mechanical power app...

medium density fiberboard (mdf) was produced using moist depithed bagasse stored dry or wet. the duration of storage for either method varied between 0 to 4 months. two steaming temperatures of 175c and 185c were also used. mdf boards were produced in the laboratory and the common mechanical and physical properties were measured and compared. results showed that an increased steaming temperat...

BACKGROUND AND OBJECTIVES Few quantitative studies have investigated the temperature dependent viscoelastic properties of cartilage tissue. Cartilage softens and can be reshaped when heated using laser, RF, or contact heating sources. The objectives of this study were to: (1) measure temperature dependent flexural storage moduli and mechanical relaxation in cartilage, (2) determine the impact o...

Carbon nanotubes (CNTs) or graphene-based nanomaterials functionalized by different strategies have attracted great attention for energy storage due to their large specific surface area, high conductivity, and good mechanical properties. This feature article presents an overview of the recent progress in the functionalization of CNTs and graphene-based materials for energy storage applications ...

Discovered in 1991(Iijima, 1991), carbon nanotubes (CNTs) have attracted considerable attention in many fields of science and technology because of their unique structural, mechanical, and electronic properties. Their potential seemed paramount in the fields of materials science, including conductive and high-strength composites, energy storage and energy conversion devices, sensors, field emis...

BACKGROUND Below-knee amputees commonly experience asymmetrical gait patterns and develop comorbidities in their intact and residual legs. Carbon fiber prosthetic feet have been developed to minimize these asymmetries by utilizing elastic energy storage and return to provide body support, forward propulsion and leg swing initiation. However, how prosthetic foot stiffness influences walking char...
