This work proposes a graded metamaterial-based energy harvester integrating the
piezoelectric energy harvesting function targeting low-frequency ambient vibrations (< 100 …

We experimentally achieve wave-mode conversion and rainbow trapping in an elastic
waveguide loaded with an array of resonators. Rainbow trapping is a phenomenon that …

In maritime transportation, a fender acts like a bumper to absorb the kinetic energy of a boat
berthing against a jetty, pier wall, or other boats. They have high energy absorption and low …
