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.

Domains are areas in the ferroelectric crystal that have the dipole moments aligned in the same direction. Piezoelectricity is a material property where the crystal generates electrical charge under ...

Piezoelectricity was discovered by two French scientists’ brothers, Jacques and Pierre Curie, in 1880. They found out about piezoelectricity after first realizing that pressure applied to quartz or ...

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 ...

Scientists harness the power of lysozyme, a protein found in tears and egg whites, to make energy. Scientists harness the power of lysozyme, a protein found in tears and egg whites, to make energy.

As if its list of properties was not already impressive enough, materials scientists working with sophisticated computer models at Stanford University have added another useful trick to graphene’s ...

Bulletin mathématique de la Société des Sciences Mathématiques de Roumanie, Nouvelle Série, Vol. 48 (96), No. 2 (2005), pp. 209-232 (24 pages) We study the frictional contact between an ...

In recent years, wearable energy harvesters and sensors have gained significant attention for several applications, including human-machine interfaces, robotics, and personalized healthcare.

Piezoelectric materials generate mechanical strain under an applied electric field, and vice versa. Over the past 20 years, these materials have come into wide use in inkjet printers, guitar pickups, ...

Piezoelectricity ( /piˌeɪzoʊˌilɛkˈtrɪsɪti/) is the charge which accumulates in certain solid materials (notably crystals, certain ceramics, and biological matter such as bone, DNA and various proteins ...
