3-3 진동 모드 압전 캔틸레버 에너지 하베스터의 제조 및 전기적 특성

A piezoelectric cantilever energy harvester (PCEH) driven in longitudinal (3-3) vibration mode was fabricated, and its electrical properties were evaluated by varying the resistive load. A commercial PZT piezoelectric ceramic with a high piezoelectric charge constant ( $d_{33}$ ) of 520 pC/N and t...
