<p>An electromagnetic energy harvesting device includes: a first vibratory structure (224) and a second vibratory structure(226). The first vibratory structure (224) is adapted to vibrate when excited by ambient vibration with low frequency, and transfers its vibration to the second vibratory structure (226). The second vibratory structure (226) is adapted to self-vibrate in a magnetic field at its high natural frequency, and generates magnetic flux change to induce electrical power.</p> |
