A pair of chemists at Michigan State University has observed the piezoelectric effect in liquids for the first time. In their paper published in The Journal of Physical Chemistry Letters, Md. Iqbal ...

Hafnium oxide thin films are a fascinating class of materials with robust ferroelectric properties in the nanometer range. While the ferroelectric behavior is extensively studied, results on ...

One of the reasons gold is so valuable is because it is highly unreactive—if you make something out of gold, it keeps its lustrous radiance. Even when you can react it with another material, it’s also ...

Diamond, long deemed non-piezoelectric, now shows stable voltage generation in ultrathin flexible membranes, unlocking ...

Piezoelectric materials play a pivotal role in wearable sensors 1. Drawing from the mechanism of pressure signal propagation, the utilization of polytetrafluoroethylene (PTFE) and fluorinated ethylene ...

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 ...

How the piezoelectric effect can be used with a special nylon for energy harvesting. How the nylon was modified during ...

Plates and shells are widely used as load-bearing structures in various equipment like carrier rockets and underwater vessels. These structures not only need to meet static the load requirements but ...

This article appeared in Electronic Design and has been published here with permission. Providing power to implanted medical devices is a major challenge. Obvious approaches such as using a ...

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 ...

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 ...

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 ...
