The subject of the research were the static and dynamic properties of a new
PVDF-based transducer. The tested transducer was a cable consisting of an
internal semiconductive electrode, a PVDF material and an external electrod
e in the form of a thin layer of semiconductive lacquer with copper wire fo
r providing electrical contacts. The measurements of electrical signals (el
ongation, force, electrical charge) received under mechanical tension are p
resented. Piezoelectric coefficients d and g for tension were calculated on
the basis of the measurements. The results can be used to make mechano-ele
ctrical models of such transducers. (C) 2001 Elsevier Science B.V. All righ
