A sensor is disclosed comprising a laminate structure and including: a first outer sheet layer of heat resistant material 1; a first adhesive layer 2 adhesively bonded along the first surface of the first adhesive layer to the first outer sheet layer; a fibre sensor element resting on the second surface of the first adhesive layer; a second adhesive layer 4 having a first surface adhesively bonded to the second surface of the first adhesive layer and with the fibre element sandwiched therebetween; and a lid layer 5 adhesively bonded to the second surface of the second adhesive layer. Preferably the first and second adhesive layer each comprise an aperture and the apertures overlap to form an aperture region, with the fibre sensor element positioned within it. Preferably the fibre sensor element rests on a second sheet layer 3, comprising a curved channel. Preferably the sensor is a temperature sensor and the invention isolates the sensor from the effects of strain.
