Stapleton says that the extent of the piezoelectricity in lysozyme crystals is significant.
Professor Tofail Syed, from the university's physics department, said: "Crystals this field yesterday are the gold-standard for measuring piezoelectricity in non-biological materials.

Piezoelectricity is a reversible property possessed by a selected group of materials that does not have a center of symmetry.
A preliminary study by researchers at the University of Michigan Ann Arbor tested an energy-harvesting device that uses piezoelectricity -- electrical charge generated from motion.
In a preliminary study, researchers tested an energy-harvesting device that uses piezoelectricity - electrical charge generated from motion.
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].
