Generating electricity from air flow

A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity. ...

Straintronics: Engineers create piezoelectric graphene

In what became known as the 'Scotch tape technique," researchers first extracted graphene with a piece of adhesive in 2004. Graphene is a single layer of carbon atoms arranged in a honeycomb, hexagonal pattern. It looks like ...

Piezomagnetic material changes magnetic properties when stretched

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds ...

Study reveals missing boundary in PZT phase diagram

(Phys.org) —Piezoelectric materials, which produce electricity in response to mechanical stress, account for a $12 billion global industry that is projected to grow at a rate of 13.2% per year, according to a recent report ...

Lab-on-a-chip technology gets a flexible upgrade

Microfluidic devices move liquids through tiny, hair-sized pathways carved into glass slides and have distinct advantages over traditional laboratories when it comes to medical diagnostics. At these reduced scales, fluid ...
