An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

Scientists have developed a hyper-stretchable elastic-composite energy harvesting device called a nanogenerator. A research team led by Professor Keon Jae Lee of the Department of Materials Science ...

Your legs are like springs. When you run, you stretch those springs -- in particular the Achilles tendon, and to a lesser extent the arch of the foot -- and store energy that's then released to power ...

Introduction If you've ever been shot with a rubber band then you know it has energy in it—enough energy to smack you in the arm and cause a sting! But have you ever wondered what the relationship is ...

Potential energy is the energy stored of position by an object. It is a type of energy that can be converted to other forms and related to some attractive or pushing forces. Gravitational potential ...
