Cloaking-enhanced metastructure for tunable vibration control and energy harvesting

A multifunctional vibro-acoustic metastructure is designed by combining nonlinear magneto-elastic piezoelectric oscillators with cloaking technique. The structure, called a metabeam, contains evenly spaced voids filled with piezoelectric beams that create local resonance bandgaps and convert vibrations into electrical energy. A cloaking method using boundary reinforcement and mass redistribution surrounds these voids to keep the dynamic properties of the structure stable while improving tunability and strength. Magnetic forces allow the system to adjust its frequency range and show different behaviors (bistable, monostable, or chaotic) by changing the distance between magnets. Experimental tests confirm the predictions, showing strong performance in chaotic conditions, where the system produced 5.3 V and 46.6 μW at 8 g, enough to power seven LEDs. This metastructure offers promising applications in energy harvesting, vibration control, and power supply for small electronic devices such as wireless sensors and OLED displays.
