This manuscript presents a new experimental wind generator based on piezoelectric energy conversion for low power applications. The aim is to demonstrate an alternative renewable energy generation method for low power applications. The generator has four blades of a propeller equipped with a total of twenty-four (24) thin film piezoelectric transducers (TFPTs). The output voltage is generated using a newly developed circuit topology. The generator was tested at three wind speeds 10 m/s, 14 m/s and 18 m/s, with a maximum output voltage of 10.2 V being produced at a wind speed of 18 m/s. Results show that this generator has promise to be suitable for low power batteryless applications, for example wireless sensor nodes (WSN).

For managing the soaring power demand, various types of Energy Harvesting Systems (EHS) have been developed. The energy harvesting from unutilized natural renewable sources using piezoelectric transducers is one of them. Day-by-day different analytical models are being reported with different piezoelectric transducers to improve the energy efficiency and output power of the energy harvesting systems. The goal of this paper is to review the PEH (Piezo-electric Energy Harvesting) systems developed in last decade to harness energy required for small electronics. The Piezo-electric energy harvesting system works on the phenomena of direct piezo-electric effect; i.e. the transducer generates electric energy when it is exposed to mechanical stress/pressure/vibration. The suitability of piezo-electric transducer for different applications depends upon the piezo-electric materials, their shapes and configurations. In this article the different piezoelectric materials and the transducer configurations have been discussed. The performance parameters of different piezo-electric energy harvesting systems have been analyzed and the scope of improvement in the existing systems has been discussed in this manuscript.

“…They parallelly connected the PZTs to each other in the energy harvester being developed. Akkaya and Özdemir [8] designed an energy harvester that could convert wind energy to electric energy with the help of PZTs and in this harvester; they parallelly connected five branches consisting of five PZTs and a bridge rectifier at the output of each one. In addition to presenting a rectification strategy with low‐voltage drops, the circuit topology proposed in this study also solves electrical connection problems between more than one PZTs.…”

“…The increase in the amount of power generated by energy generation systems based on piezoelectric energy transformation has made the use of these materials in the generation of renewable energy more and more popular. The experimental study conducted by Akkaya and Özdemir can be given as an example to studies in this field [8]. With a small‐scale generator developed in this study, wind energy can be directly turned into electric energy.…”

In order to maximise the power from a harvester including a great number of piezoelectric transducers (PZTs), the outputs of these transducers should be connected in a suitable way. Since each PZT can be thought of as a non-ideal source, it is also clear that direct serial connection or parallel connection of these PZTs will not be a very good strategy. In this study, a new circuit topology is proposed for the electric connection between PZTs in a harvester including a great number of PZTs. This proposed circuit topology at the same time presents an efficient rectification and regulation strategy for each PZT used. The process of rectification takes place with minimum voltage loss due to the structure of the proposed circuit topology. In addition, the output of the proposed circuit topology can be used directly to charge an energy storage unit in addition to being connected to the input of any interface circuit. An experimental setup was designed to compare the performance of circuit topology proposed in this study in the form of connection used commonly in the literature. With this experimental setup used, various connection forms and the proposed circuit topology were compared under the same conditions.
