- •
We report the development of a polymer coating for fibre Bragg grating based humidity sensors.
- •
PMMA and its co-polymers were investigated leading to structural modifications of a synthesised polyetherimide coating with a measured Bragg wavelength shift of 1.45 pm/%rh, an improvement over unmodified polyetherimide.
- •
The commercially available P84 polyimide (Evonik) was investigated and a Bragg wavelength shift of 5.29 pm/%rh measured.
- •
A modified polyimide is now in development.
