eng	Functionally Graded Materials for Sensor and Energy Applications	Principles, preparation, characterisation, and application of functional materials containing a gradient of their functional properties are surveyed, with main emphasis on thermoelectric (TE) materials for application in sensors and thermogenerators. Further examples of the implementation of functionally graded materials (FGM) presented are dielectric thin-film stacks for capacitors with low temperature coefficient, microwave-processed structural gradients in fuel cell electrodes, and zone-melted graded (Bi1-xSbx)(2)Te-3 materials for Peltier coolers. Preparation and properties of compositional gradients in TE solid solutions (FeSi2 doped by alloying, (Bi1-xSbx)(2)Te-3, Mg-2(Si,Ge,Sn), PbTe) are analysed, as well as composites joining thermoelectrics of dissimilar chemistry and joints to metallic contacts and interlayers. Thermal spraying of doping-graded FeSi2 was developed as a preparation technique of TE silicide-based FGM.	FGM;thermoelectrics;silicides;thermal sensors;energy conversion
