Hexagonal Microbolometer Pixel for Flexible Substrates
Nature becomes an inspiration source to many imaging system researches. Imaging features owned by biological forms such as high resolution, wide field of view, high depth of field, high sensitivity to motion and light are attractive reasons to mimic the nature in imaging system applications. In this study, an arthropod eye’s hexagonal shaped ommatidia are taken as a model for uncooled microbolometer pixel structure. A hexagonal pixel with 34 μm diagonal length which has the thermal conductance value of 1.48x10-7 W/K and the time constant value of 0.69 ms is designed for the first time in literature.
