- Description: Abstract: Autonomous systems source energy from waste heat which are generated by home appliances and industrial machineries and mitigate the effect of global warming which threatens the environment as a result of fossil fuel energy based sources that release undesirable carbon-monoxide into the atmosphere. This paper described current waste heat recovery practices in different applications, and an innovative approach to convert heat energy into usable forms. This can significantly contribute towards sustainable energy development and meet the growing need for power in small scale applications due to its relative advantages over other sources of energy generation. It will help in optimizing existing waste recovery technologies and developing new heat recovery technologies and gives an insight into various ways by which waste heat can be exploited to meet the growing energy demand and increasing interest in space exploration, satellite activities, structural health monitoring and terrestrial monitoring in harsh and inaccessible environments place a high demand for energy sources for autonomous systems.

- Description: Abstract: In this study, polyurethanes embedded with Nickel-Titanium (NiTi) SMAs is investigated by experimental methods to understand the mechanical properties of the embedded SMAs with the aim of using them as active and passive surfaces in various applications. A matrix composite was utilized for the production of the silicone moulds and casting of the specimens. The implanted NiTi SMA wires were cut into required lengths using and aged at 2500C and pre-strained by 3%. to ensure homogeneous behaviour. For each of the SMA/polyurethane composites, the treated NiTi SMA wire was properly located in the groove created in one half of the silicone mould the polyurethane resin was poured and cool to room temperature in vacuum casting machine. The result shows that the mechanical properties embedded SMA increased in of the SMA/polyurethane composite. The improvements in the properties cannot be sustained at high temperature owing to degradation of interfacial strength between the SMA and polyurethane 2 interface due to high recovery stress generated by the SMA upon activation...
