Self-Charging Power Cells and Batteries: What Are They?

# We typically think of energy generation and energy storage as two different processes requiring two separate devices, but recent advances have revealed that we can, in fact, do both with just one device. Research into self-charging power cells and batteries continues to accelerate as the cells become more efficient and

Piezoelectric Effect vs. Piezoresistive Effect

# The word "piezo" is derived from piezein, which is Greek for physical pressure in one form or another. Piezo devices, which come in piezoelectric or piezoresistive varieties, are activated through some form of physical pressure. The effects of such pressure depend on the type of device in question.   So, what are

The Piezoelectric Effect: Technology Generates Functional Benefits

# Anyone not familiar with it might immediately ask: What is the piezoelectric effect? It describes the various processes of electricity generation using a piezoelectric material.   Technically, the piezoelectric effect is described as the linear electromechanical interaction between the mechanical and electrical state in crystalline materials that have no inversion symmetry.   APC International

Piezo Materials for High Power Applications Made in the USA!

Piezoelectric ceramics manufactured from "hard" piezo materials are characterized by having higher mechanical quality factors (Qm) and lower dissipation factors (dielectric losses, tanD) relative to soft PZT's. Ceramic components produced from these "hard" compositions are less susceptible to depolarization from heating under high duty cycles and/or stress. Generally, a lower
