Researchers have reported that piezoelectricity in GaN and ZnO nanowires is enhanced by as much as two orders of magnitude as the diameter of the nanowires decrease. Gallium nitride (GaN) and zinc ...

(Nanowerk Spotlight) One of the greatest challenges in harnessing the power of nanotechnology is achieving dynamic control of mechanical, electronic, optical and chemical properties of nanoscale ...

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

Researchers have opened the door to low-power off/on switches in micro-electro-mechanical systems, MEMS, and nanoelectronic devices, as well as ultrasensitive bio-sensors, with the first observation ...

(Nanowerk News) Researchers at Chalmers University of Technology in Sweden and at the University of Magdeburg in Germany have developed a novel type of nanomechanical resonator that combines two ...

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 ...

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 ...

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 ...

Piezoelectricity is the ability of some materials such as crystals and certain ceramics, to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are ...
