New polymer-piezoelectric hybrid creates potential for “materials that compute”
New polymer-piezoelectric hybrid creates potential materials that compute
2015/7/13
Moving closer to the possibility of "materials that compute" and wearing your computer on your sleeve, researchers at the University of Pittsburgh Swanson School of Engineering have designed a respons...

2010/10/12
Environmental concerns are strongly driving the need to replace the lead-based piezoelectric materials currently employed as multilayer actuators. The current review describes both compositional and s...
Modified strip saturation model for a cracked piezoelectric strip
Applied mechanics Crack growth rate Piezoelectric ceramics
2009/12/2
Purpose: The investigations aim to propose a model for arresting an electrical opening of a crack which weakens
a narrow, poled and infinite piezoelectric strip. The edges of the strip are subjected ...

Lead-free piezoelectric ceramics (1−x)(Na0.5K0.5)NbO3-xBiFeO3 (x = 0 0.07) were
synthesized by the solid-state reaction. Differential scanning calorimetry (DSC) measurements
revealed that an...
