Even though the vibration frequency is as low as 1 Hz, two orders-of-magnitude improvements in normalized power (the ratio of power to product of external force and coil turns) provided from previous reports can be obtained. Further, comparing our device with maturely accelerometer chip (MMA7361) indicates that proposed strategies benefit harvesting vibration energy on driving automobile indeed. This vibrated power generator inturn provides high potential for applications, such as human motion (1 Hz ∼ 2 Hz), sporting (5 Hz ∼ 10 Hz), and automotive (10 Hz ∼ 1 kHz) etc. © 2012 IEEE. |
