A significant increase of the surface energy of the powder and the piezoelectricity
was found in the composites with the ceramic powder with bigger particle size.

The result: a form of PVDF that displays the intriguing property of piezoelectricity
(from the Greek word "piezein," meaning to press), first reported in crystals such as quartz and sodium chloride in the early 1880s by Pierre Curie and his brother Jacques.
Thus, stretching provides us a new method to generate the [gamma]-form structure of potential piezoelectricity
is a well-known effect in which stretching or compressing a material causes it to generate an electrical voltage (or the reverse, in which an applied voltage causes it to expand or contract).
Key words: tactile sensors, piezoresistive materials, robotics, PVDF, piezoelectricity
, object recognition
semiconductivity of proteins, piezoelectricity
of tissue), while on the other hand he studied facts from the field of electronics, physics of semiconductors and cybernetics.
To quote Fukada, whom the others regard as a pioneer in the subject, "Stress-induced electricity in bone is caused by both piezoelectricity
in collagen and streaming potential in microcanals in bone.
Part 1 Materials and design of ultrasonic transducers: Piezoelectricity
and basic configurations for piezoelectric ultrasonic transducers
is the phenomenon whereby certain materials produce an electric charge when the material is under stress.
is the accumulation of a charge in a solid in response to mechanical stress.
