There is a need for methods that can produce piezoelectric composites having suitable physical characteristics and also optimized electrical stimulatory proper-ties. The present application provides piezo-electric composites, including tissue-stimu-lating composites, as well as methods of making such composites, that meet these needs. In embodiments, methods of making a spinal implant are provided. The methods suitably comprise preparing a thermoset, thermoplastic or thermoset/thermoplastic, or copolymer polymerizable matrix, dispersing a plurality of piezoelectric particles in the polymerizable matrix to generate dispersion, shaping the dispersion, inducing an electric polarization in the piezoelectric particles in the shaped dispersion, wherein at least 40% of the piezoelectric particles form chains.

Composite reinforcing strip comprising: a covering capsule surrounding a plurality of longitudinal channels developing parallel to a longitudinal development direction of the composite reinforcing strip and arranged in sequence between opposite lateral ends of said composite reinforcing strip, a plurality of longitudinal reinforcing fibres arranged inside reinforcing channels of the plurality of longitudinal channels, and a plurality of longitudinal permeable fibres arranged inside at least one permeable channel of the plurality of longitudinal channels.

The covering capsule has, at least at an upper surface of the covering capsule opposite to a lower surface of the covering capsule, a plurality of surface openings leading to the at least one permeable channel so as to define a fluid communication between the plurality of longitudinal permeable fibres and an external environment.
