Tunable Plug‐and‐Play Meta‐Nanogenerator Materials for Multi‐Range Force Measurements

Advanced Science, EarlyView.
The multifunctional and tunable meta‐nanogenerator material system combines a mechanical metamaterial and a triboelectric nanogenerator enabling self‐powered, real‐time force sensing across application‐specific ranges. Geometrical tuning adjusts stiffness and the force sensing range, while modular integration streamlines assembly.

Fiber Reinforced Concrete (FRC)

International Journal for Research in Applied Science and Engineering Technology
A detailed experimental investigation was conducted on the use of natural fibers—bamboo fiber, coconut fiber, and human hair fiber—as reinforcing agents in concrete. The primary aim was to explore their feasibility as sustainable, costeffective, and eco-friendly alternatives to synthetic fibers like polypropylene or steel.
