Temperature sensing device 700 to sense aircraft wheel brake temperature, the temperature sensing device comprising a sensing device substrate 602; and one or more package layers attached to the sensing device substrate, wherein: the sensing device substrate carries one or more electronic components 302 for sensing temperature. Preferably the electronic components comprise a surface acoustic wave Saw sensor mounted to the substrate and a sensor antenna 304 coupled to the SAW sensor. The package layers may comprise a first package layer 610 on a first surface 608 of the substrate to cover the sensor antenna and SAW sensor and also may comprise a second package layer 702. A method of manufacturing a temperature sensing device to sense aircraft wheel brake temperature, and a wireless relay device to wirelessly transmit an interrogation signal to a temperature sensing device and wirelessly receive an output signal from the temperature sensing device are also claimed.
