WEST LAFAYETTE, Ind. – A multidisciplinary team of researchers led by Steve Son, a professor of mechanical engineering at Purdue University, has received a $7.5 million grant by the Air Force Office ...

Energy-harvesting, or “scavenging,” systems extract energy from the ambient environment. Unfortunately, these power generators supply much less energy than do standard batteries. However, thanks to ...

Piezoelectric buzzers find wide use as audible-signal generators because of their low power consumption and clear, penetrating sound. An external driver or a self-driven circuit that oscillates at the ...

These small and strong materials offer a wide frequency range, suiting a variety of applications and specific design needs without sacrificing performance. Electronic engineers are no strangers to odd ...

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...

A lighted footpath powered partially by piezoelectric tiles will soon be operational at the Kennedy Space Center. jtoon@gatech.edu ...

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 ...

Parquet power: fungus-treated wood could soon be used to create energy-generating floors. (Courtesy: Pazzo4562/CC BY-SA 4.0) Infecting wood with wood-decay fungus can boost its piezoelectric output by ...

Tunability in lenses typically requires bulky components, but researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied.

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 ...
