This thesis presents the design and development of quasi-static 2-dimensional Flexible Printed Circuit Board (FPCB) based micromirror for portable laser marking/ engraving system. It focuses on the modelling and prototyping of the novel 2-dimensional electromagnetic actuated micromirror which can be used in place of two 1-dimensional micromirrors having the benefits of lower footprint in size of the scanner and efficient alignment with the incident laser beam. This 2-dimensional micromirror can be used in portable low power laser marking/ engraving system ideally designed for consumer applications like printing name cards, engraving jewellery etc. The problem of drifting/ creep associated with quasi-static mode of FPCB based micromirror actuators is analyzed and Zero method is proposed to minimize the drifting issue which is proven experimentally in the thesis. From this thesis work, it is evident that the developed 2-dimensional, low-cost, quasi-static FPCB based micromirror would be a suitable candidate for replacement of the expensive conventional MEMS bonded mirrors in the market.
