A device comprising a bendable fibre comprising a fibre axis, a thermally expandable material and a resistance wire extending longitudinally through the fibre spaced apart from the fibre axis;
- wherein, in use, electrical power applied to the resistance wire causes the temperature of the resistance wire to increase.
A method of manufacturing a bendable fibre comprising a fibre axis, thermally expandable material and a resistance wire spaced apart from the fibre axis using a draw apparatus, the method comprising the steps of:
- providing a preform comprising a preform axis, a thermally expandable material and a resistance wire channel extending longitudinally through the preform spaced apart from the preform axis, to the draw apparatus;
- heating a portion of the preform;
- drawing the heated portion of the preform in order to form a fibre;
- and
- feeding a resistance wire into the resistance wire channel during or after the draw such that the resistance wire is positioned within the resistance wire channel of the fibre spaced apart from the fibre axis.
