| We introduce novel Magneto-Mechano-Electric (MME) harvesters with colossal energy density can turn on 20 LEDs under miserably weak magnetic field at low frequency. The MME harvesters are magnetoelectric (ME) laminates composed of (011) oriented anisotropic single crystal fiber composite (SFC) bonded on Ni plate and Nd permanent magnet proof mass. The ME laminate has strong ME coupling (ME ~160 V/cmOe) at zero magnetic bias. It is also found that the MME harvester of ME laminate with permanent magnet proof mass generates colossal output power density of 47 mW/cm3Oe2 under weak magnetic field of 1.6 x 10-4 T at 60 Hz. This MME harvester can be potential ubiquitous power source for sensor networks by harvesting tiny parasitic magnetic energy induced from electric power cables. |
