The applications of intelligent shape-memory materials in robotics and the construction of electromechanical command and control devices are based on the properties of some alloys to modify their geometry when they undergo phase transitions to modify the martensite-austenite crystalline structure [1]. After phase transitions, forces are developed that can act conveniently and perform the desired operations by the designer. We have realised some applications using smart shape memory materials with different geometries and different physico-mechanical characteristics [2-4]. Continuing these concerns, in this paper, the thermomechanical properties of SMA bands and wires are studied, the results being used in the design of electromechanical devices. Figure 1 Figure 2 Thermal measurements performed on SMA bands revealed phase transitions, for which process enthalpy was calculated (Figure 1). Mechanical and thermomechanical properties for the same material were determined by DMA and TMA. By AFM measurements, interaction of intelligent alloys with several azo-food dyes has been highlighted. Figure 2 shows the deposition on the SMA band of E155 food dye. SMA characterization is complemented by magnetic studies.
