The piezoelectricity in such a material may be due to several effects, thus research into the mechanism of piezoelectricity and the enhancement of activity by new forming and poling processes and synthetic methods is still required [4].
Some material that first appeared in the 2000 revised first edition is included here, as well as new topics such as piezoelectricity, groups, subgroups and supergroups, liquid crystals, incommensurate materials and the structure of foamed and amorphous materials, and martensitic transformation in nickel-titanium shape-memory alloys and zirconia ceramics.
Interest in piezoelectricity of polymers arose in the second half of the 20th Century when Kawai claimed that poled thin films of Polyvinylidene Fluoride (PVDF) exhibited a large piezoelectric coefficient.
One way would involve stringing quartz crystals, which can transfer electricity via piezoelectricity, underground along known fault lines.
However, in AE measurements of ferroelectric materials under electric fields, there are two possible kinds of AE signals: AE signals from within the ferroelectric sample and vibro-acoustic emission (vibro-AE) signals related to the piezoelectricity of the sample [6].
