一个灵活的单晶PMN-PT压电能量采集器被证明可以实现自供电的人工心脏起搏器。能量收集装置产生0.223 mA的短路电流和8.2 V的开路电压，这不仅足以满足商用电池充电的标准，而且还可以在没有外部电源的情况下刺激心脏。
A flexible single-crystalline PMN-PT piezoelectric energy harvester is demonstrated to achieve a self-powered artificial cardiac pacemaker. The energy-harvesting device generates a short-circuit current of 0.223 mA and an open-circuit voltage of 8.2 V, which are enough not only to meet the standard for charging commercial batteries but also for stimulating the heart without an external power source.
