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 ...
Penn State's research on KNN piezoelectric materials reveals potential for efficient energy harvesting and biocompatible ...
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 ...
Cheap piezo buzzers are everywhere. They’re so cheap that they can be used in novelty birthday cards. Applying an alternating voltage across a piezo crystal makes it expand and contract, and fixing ...
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 ...
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 ...
