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).

“…[ 177 ] The composite cantilever structure on the basis of the main BaTiO 3 material part consists of a slice of BaTiO 3 ceramic in thickness of 300 μm adhered to a polyethylene glycol terephthalate (PET) substrate with ITO and Ag respectively as top and bottom electrodes, where two ends of BaTiO 3 ceramic part are attached with a mass and fixed by an acrylic fixture, which makes the BaTiO 3 ceramic obtained efficient vibration. [ 178,179 ] The PET substrate and the attached mass play the roles of protective layer and effective vibration gain, respectively. Besides, the effective illumination area of the BaTiO 3 ceramic is ≈2.4 cm 2 under 405 nm LED optical radiation.…”

Ferroelectric barium titanate (BaTiO3) with an intrinsic spontaneous polarization performs multiple remarkable properties. Recently, ferroelectric BaTiO3 based materials and devices are fabricated in multi‐effects coupled systems, such as self‐powered ultrasensitive sensing, energy harvesting, and electrochemical applications, which have gained growing interest with worldwide increasing researches. This review places a focus on current achievements in ferroelectric BaTiO3 based multi‐effects coupled materials and devices for capacitors, nanogenerators, sensors, electrochemistry, and other applications. First, the structure–activity relationship of BaTiO3 materials including various crystal structures and different morphologies is reported. It is interesting that multi‐effects coupled electronic devices and systems combining multiple properties have attached significant effort to realize enhanced performance contrasted to device applications with single effect. Finally, a brief understanding of opportunities and challenges for ferroelectric BaTiO3 based multi‐effects coupled materials and devices is given. The intention of this review is to encourage more effort in this nontoxic intelligent material, and impel more attention in pushing progress of this field in the future.

The purpose of this paper is to design an energy harvester to improve output performance. The theoretical analysis of the piezoelectric energy harvester has been performed. Reducing the length of one cantilever beam, thereby changing the relative impact position, causing the amplitude of the two cantilever beams to be different, and making the waveform of two beams different. Some experiments have been tested to verify the feasibility of the device and compare the differences with Plan A. Based on the experiment, it can be concluded that the output voltage is higher at both high and low speeds. When the rotation speed is 255 r min−1, Plan B arrives at the optimum speed, and the maximum output voltage is 166.2 V, which significantly increases from 97.2 V of Plan A. The maximum output power is 0.966 W under the load resistance of 10 kΩ. The maximum voltage is 157.7 V under the load resistance of 120 kΩ. Nevertheless, the maximum voltage and maximum power of Plan A are 92.62 V and 0.52 W. Besides, the prototype has fewer materials and nearly 1.5 times the energy conversion rate compares to Plan A. It can light up 42 LEDs easily and can adapt to environmental vibration frequency changes, so it has an intensely adaptable and outstanding performance in practical applications.
