电池作为主要的便携式电源的应用不再适用，因为它的使用寿命有限。本文介绍了近年来对无线传感器节点功率需求的关注，以及利用压电器件开发能量采集系统的研究。环境能量收集是替代电池和布线的替代方案之一，在这种情况下，来自太阳能、气流或振动等环境来源的少量能量被收集起来形成电能。大量研究表明，能量采集设备的功率密度在数百微瓦范围内，而从文献研究中可以看出，大多数电子设备的功率要求在毫瓦级范围内。因此，在许多情况下，成功部署能源收集技术的一个关键挑战仍然是提供足够的电力。文末还对全波桥式整流和倍压整流两种整流方式进行了综合论述。
The application of batteries as the main portable power sources is not applicable any longer as it has limited lifespan. This paper presents the recent concern on the power requirements of Wireless Sensor Nodes and the studies on the development of energy harvesting system using piezoelectric devices. Ambient Energy harvesting is one of the alternatives in replacing the use of batteries and wiring where small amounts of energy from environmental sources such as solar, air flow or vibration is harvested to form an electrical energy. Numerous studies have shown that power density of energy harvesting devices is in the range of hundreds of microwatts, while from the literature study it reveals that power requirements of most of electronic devices are in the range of milliwatts. Therefore, a key challenge for a successful deployment of energy harvesting technology remains, in many cases, the provision of adequate power. General discussion on two types of rectifier; full-wave bridge rectifier and voltage doubler also presented at the end of this paper.
