This paper presents various aspects of the wavefront control strategies for an ultra-lightweight composite reflector made polymers large primary a space telescope, and shape is by set patterned unimorph strain actuators attached to reflector. It starts with analytical investigation mechanical behaviors strain-actuated curved shell, resulting in accurate prediction typical features, such as damp...

1 Introduction Energy harvesting (EH) research area has been emerged to build self-powered wireless electrical devices such as wireless sensors by collecting ambient or wasted energy. This EH technology is highly demanding because wireless sensors are increasingly used in the areas of structural health monitoring (SHM), building automation, and so on. The battery, a current power source for wir...

This paper begins with a quick survey of potential space applications and brief review previous experiments on the shape control spherical shell reflector thin film PVDF-TrFE. Next, problem thermal sensitivity is addressed numerically; it found that, because large expansion active material, surface figure error generated by linear gradient unimorph considerable its correction requires voltages....
