Highly twisted rods that deform helically provide these metamaterials with a high stiffness and enable them to absorb and release large amounts of elastic energy.
Water droplets under freezing conditions do not spontaneously detach from surfaces as they do at room temperature due to stronger droplet-surface interaction and lack of an energy transformation ...
Building blocks for greener energy: Reconfigurable elastic metasurface Date: April 2, 2024 Source: Pohang University of Science & Technology (POSTECH) Summary: Energy harvesting, an eco-friendly ...
Here we show that the metabolic rate of human walking can be reduced by an unpowered ankle exoskeleton. We built a lightweight elastic device that acts in parallel with the user’s calf muscles, ...
The paper is about invariants of networks by labeling and relabeling its nodes or arcs. These invariants can be used to classify networks as to their complexity, or to distinguish non-isomorphic ...
We built a lightweight elastic device that acts in parallel with the user's calf muscles, off-loading muscle force and thereby reducing the metabolic energy consumed in contractions.
Computer simulations indicate that Himalayan megaearthquakes must occur every 1,000 years or so to empty a reservoir of energy in southern Tibet not released by smaller earthquakes, according to a ...
In fact, studies over the years have concluded that between 40% and 50% of the energy you need to run is recycled from stride to stride through this elastic energy storage-and-return mechanism.
Highly twisted rods that deform helically provide these metamaterials with a high stiffness and enable them to absorb and release large amounts of elastic energy.
