The theory of Disruptive Technologies explains the evolution of technologies that disturb the status quo of both dominant technology platforms and competitive market layouts. In this paper, the theory of Disruptive Technologies for the space sector is explored. This exploration is required because the Disruptive Technology theory is currently based upon the innovation dynamics of mass consumer markets, which are significantly different from the dynamics of the low volume, highly governmentally influenced space sector. The objective is to clarify the dynamics of innovation in space (with particular respect to technological disruptions) in order to help decision makers in their effort to support innovation in the development of space technologies. This is done by analyzing the dynamics of the space sector and the theory of Disruptive Technologies in respect to its applicability to the space sector. The result of these analyses leads to the creation of a theory that is tailored to the ...

Shape memory polymers and their composites are capable to hold a temporary shape and recover to the original shape upon exposure to a particular external stimulus. The stimulus light is considered as the optical radiation of any wavelength from 1 to 10^6 nm. Light enables unique and advanced shape memory effects that can fulfill the sophisticated demands in micro and small-scale engineering, biomedical, space and large-scale engineering applications. The ability to vary the stimulus light’s wavelength, intensity, irradiated position, periodicity and polarization enables the progressions of wavelength selective, sequential, reversible and multiple shape memory effects. Current study provides a comprehensive review of the advances in experimental and numerical investigations on light activated shape memory polymers and composites. Actuation mechanisms, functionalities, characteristics, applications, merits and demerits of photoresponsive shape memory polymers and photothermal shape memory polymer composites are considered. The recent advancements on material design and optical technologies have dramatically changed the light activation scenarios of shape memory polymers. Advanced optical technologies and light dispersion methods that are advantageous for the light activation of SMPs are described. However, to date there are many unexplored areas that need to be researched further to develop sophisticated real-life applications of light activated shape memory polymers and composites. Herein the future research opportunities and directions are highlighted.
