Abstract

A piezoelectric fibre comprising a conductive core 17, a polymer based piezo active layer 18 and an electrolyte based outer layer 19. The method of producing such a fibre includes the steps of: melting the polymer; extruding the polymer through a die at a set speed; feeding conductive material through the same die at a faster speed; drawing and poling the fibre; and passing the fibre through an electrolyte solution to create an outer electrode. Also disclosed is a fabric comprising such a fibre, and uses of such a fibre. The polymer may be poly(vinylide fluoride) (PVDF) or other like polymers. The fibre generates a voltage when a mechanical or vibrational force is given to the fibre.
