A research team in China has reported a significant piezoelectric effect in ultrathin and ultra-flexible polycrystalline ...

Graphical abstract. Credit: The Journal of Physical Chemistry Letters (2023). DOI: 10.1021/acs.jpclett.3c00329 A pair of chemists at Michigan State University has observed the piezoelectric effect in ...

Piezoelectricity is used everywhere: Watches, cars, alarms, headphones, pickups for instruments, electric lighters and gas burners. One of the most common examples is probably the quartz watch, where ...

The effect: polarisation and electric field are pointing in the same direction. With positive d33, the sample expands, whereas the material is contracting when d33 is negative. Since 2011, it has been ...

The word “piezo” derives from the Greek word piezein, meaning “to press tightly”. Piezoelectricity refers to a material’s ability to convert mechanical energy (pressing) into electric energy ...

Why dual-source harvesting offers benefits for powering implantable devices. How the dual-source harvester was constructed, along with its operating principles. The results achieved with this device ...

Piezoelectricity is a material’s capacity to transform mechanical energy (pressing) into electric energy (polarization) and vice versa. The word “piezo” derives from the Greek word piezein, which ...

Researchers have found a new method to induce the piezoelectric effect in materials that are otherwise not piezoelectric. It can pave the way for new uses and more environmentally friendly materials.
