A new device that harvests energy from raindrops, winds or sunlight has been invented at the Institute for Materials Research and Innovation at the University of Bolton, UK. Elias Siores led a team who created a special polymer with piezoelectric and photosensitive properties.
Imagine that one day you could charge your mobile phone or other low-consumption devices just by placing them in noisy areas or by yelling at them. South-Korean scientists from the Sungkyunkwan University in Seoul, are now studying a type of zinc oxide-based device that could do just that.
When cars or trains move on the surface of the earth, they produce vibrations. These vibrations can be captured and directed through underground piezoelectric materials to a smart grid or roadside batteries.
Researchers from the University of Notre Dame in the US have designed a PZT (lead zirconate titanate) piezoelectric device that resembles skin (they called it the EH skin) and that can harness energy from the mechanical work applied to it. The new device can be used in a variety of applications, ranging from wireless sensor units to patches that get energy from vibrations and pass it on to the grid. The sample they tested got as much as 3.7 mW.
We’ve been presenting over time how piezoelectric devices could harness energy from different sources, and I think we were right supporting this technology. The following is a Press Release sent to us by California Assemblyman Mike Gatto, who proposed a new bill that will implement piezoelectric technology already in use in Italy and Israel to harness energy from road vibrations.
A group of undergraduate students at Cornell University has conceived a device that can harness wind-induced vibrations into electricity through the piezoelectric effect. The Vibro-Wind Research Group is led by Frank Moon, Joseph Ford Professor of Mechanical and Aerospace Engineering.
After modifying Israeli highways to produce energy from piezoelectric pads installed beneath the asphalt, Innowattech, an Israel-based company, now applied their technology on railroads.
Piezoelectrics are a class of materials that, if applied a mechanical force, exert an electric current on the sides. You may already have knowledge about this, but researchers are studying how to take piezoelectric materials to the next step.
A group of researchers at the University of Bolton have created a new piezoelectric-photovoltaic fiber that has the possibility to be implemented into different gadgets to power them using light and motion.
A Louisiana Tech University professor, dr. Long Que, has designed and prototyped a composite material that converts heat into electricity by using simple physical mechanisms found in piezoelectric materials and carbon nanotubes.
Dr. Yong Shi, from Stevens Institute of Technology has released a paper called “1.6 V Nanogenerator for Mechanical Energy Harvesting Using PZT Nanofibers.” He uses piezoelectric nanowire- and nanofiber-based generators that can convert mechanical energy into electricity.
The water that you unleash when you take a shower (with the “hot” knob closed) has two properties: pressure and temperature. You can change pressure, but to raise its temperature you usually need extra energy. Regularly, you don’t shower with the water knob turned to the maximum, so a certain extra pressure exists in the tubing, creating friction.
