Piezo-ceramic PZT fibres are drawn using a textile spinning method which produces fibres with standard diameters of 105 μm, 250 μm and 800 μm and with typical lengths of 75 and 150 mm. Piezo-composite ...

Piezoelectric materials have emerged as central to modern energy harvesting strategies, offering a direct means to convert mechanical stress or vibration into electrical energy. This ability is ...

In a study conducted at the University of Connecticut, a team led by Asst. Prof. Thanh Nguyen and postdoctoral fellow Yang Liu explored the use of a "tissue scaffold" made out of nanofibers of a ...

Piezoelectric materials hold great promise as sensors and as energy harvesters but are normally much less effective at high temperatures, limiting their use in environments such as engines or space ...

Heat and pressure can deteriorate the properties of piezoelectric materials that make state-of-the-art ultrasound and sonar technologies possible -- and fixing that damage has historically required ...

The increasing miniaturization and sophistication of electronic products, ranging from consumer media devices to medical diagnostic tools to defense-related sonar applications, presents a bounty of ...

Piezoelectricity is a property of certain materials to become electrically polarized under strain and stress. This phenomenon has been studied extensively since it was first discovered in the mid-18 ...

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 ...

Since the EU enacted the Restriction of Hazardous Substances directive (RoHS) several years ago, which bans several substances in electronics that are deemed hazardous, lead has become a material non ...
