Piezoelectric energy harvesters (PHE) have drawn significant interest as a method of harvesting environment energy to power because of its compatibility and high energy density. Integrating piezoelectric energy harvesters into wireless sensor networks, Internet of Things (IoT)) devices, and wearable electronics enhances their functionality and also increases sustainability. This integration can be lead to the development of self-powered devices that can operate continuously without the need for external power sources. The problem occurs while using PEH are the low level of harvested power and extraction of maximum power. The extracted output power need rectification and the output voltage need to be regulated. To overcome these problems piezoelectric energy harvester or transducer cannot be used alone to harvest mechanical energy. To increase the output voltage and power it is necessary to choose a piezoelectric material, piezoelectric transducer as well as an electric circuit. In this paper, we discuss different circuits such as Switch only rectifier circuit, Voltage multiplier based energy harvesting circuit, Synchronised Switch Harvesting on Inductor (SSHI) and Synchronous Electrical Charge Extraction (SECE) to harvest piezoelectric energy. The design and optimization of the circuits were done by using Multisim software. Physically, a stack transducer is developed by using PZT materials and integrated into the electrical circuit. The output voltage of 1.2 V to 1.9 V is recorded by using the human thumb impression to piezoelectric element and this voltage is sufficient to glow an LED bulb.
