VIDEO ON THE TOPIC: Piezoelectric Effect Explained

Piezoelectric energy harvesting: Developments, challenges, future The days when piezoelectric energy harvesting was considered unreliable and had low power output are long gone. Hand in hand with the development of ultra low power electronics, energy harvesters have been drastically improving also. Jan 10, Dr Harry Zervos.

The days when piezoelectric energy harvesting was considered unreliable and had low power output are long gone. Basic input-output principle of piezoelectric energy generators. Source: Arveni. The improvements in reliability and output, along with the convergence of developments of associated technologies have led to an interest in the market for energy harvesting that is spurring further growth.

The number of units will rise from million this year -predominately used in cigarette lighters currently, but bound to be utilised in more complex devices such as remote controls, sensors and wireless sensor networks - to million units in For more information read the IDTechEx report "Piezoelectric Energy Harvesting Forecasts, Technologies, Players" highlighting the opportunity, challenges and trends with the technology.

For full details see: www. There are over piezoelectric materials that could be used for energy harvesting , with the appropriate ones being selected for each application. Although barium titanate was the first piezoelectric ceramic discovered, the ceramic lead zirconate titanate, also known as PZT, is still the most commonly used material for piezoelectric harvesting.

Alternatives are receiving some attention, usually where efficiency and temperature performance of the material itself is not the primary consideration but factors such as flexibility, light weight or even toxicity concerns come to the fore.

For instance, sodium potassium niobate exhibits properties very similar to PZT without containing lead; or there are polymer piezoelectric materials such as polyvinylidene difluoride, in which piezoelectricity is due to intertwined long-chain molecules attracting and repelling each other when an electric field is applied.

Wide band harvesting - innovative architectures. A challenge of piezoelectrics is that while they are efficient at optimal resonance, only a slight variation away from the optimal resonant frequency causes a significant reduction in energy generation - the bell curve is very steep.

Some try to compensate for this by using magnets to limit the vibrations within the main resonance of the device, which adds bulk and cost and does not enable true broadband ability. Another solution offered is to electronically pre-bias the piezoelectric material. A charge put on the material acts as a damper and requires the material to do more work against it. As a result, a power gain up to 20 times has been demonstrated when compared to an optimal resistive load.

Focusing on basic scientific principles that demonstrated how the "33" longitudinal excitation mode on piezoelectric harvesters is characterised by 3 times higher energy conversion efficiency than the "31" transverse excitation mode, the NIA researchers described the design and construction of a hybrid piezoelectric energy harvesting transducer that can harvest 4 times more energy than a traditional "31" harvester.

In , researchers at the NPL National Physical Laboratory in the UK also demonstrated some really interesting results, which initially might seem counter-intuitive. NPL scientists found that reducing the amount of piezoelectric material covering a typical cantilever energy harvesting structure increases the power output. This means that, in order to get the most energy out of your device, you only need to cover the cantilever for two thirds of its length.

Arveni 's piezoelectric harvesters are enabling a variety of applications: remote controls, wall switches for home automation and building infrastructure, the biggest adopter of energy harvesting technologies so far.

The company calls its product a "Pulse Harvester", as it delivers a small amount of electrical energy up to 2 mJ in response to a user action such as a push or a twist. MicroStrain , a company recently acquired by the Lord Corporation further integrates piezoelectric energy harvesters in applications as niche as the condition monitoring of rotor blades in helicopters, powering the harvester through the rich vibration environment in which it operates.

And talking of micro Microgen , a spin out from the University of Vermont is looking into miniaturising piezoelectric harvesters, generating microwatts of power for applications with lower power requirements, such as wireless sensor networks or tyre pressure monitoring systems.

Piezoelectricity is the electric charge that accumulates in certain solid materials such as crystals , certain ceramics , and biological matter such as bone, DNA and various proteins [1] in response to applied mechanical stress. The word piezoelectricity means electricity resulting from pressure and latent heat. The piezoelectric effect results from the linear electromechanical interaction between the mechanical and electrical states in crystalline materials with no inversion symmetry. For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.
