Two bimorph array facing opposite to each other are designed and attached with metal micro plates. The micro solar cell (or) film can be placed on the top of each plate for storing the energy. With respect to the direction of sun light, one bimorph array receives more energy in the form of heat than the other and deflects accordingly. The deflection of the bimorph array depends on the material used for the configuration.

The thermal bimorphs and microplates are designed using COMSOL Multiphysics 4.1. With the Solid Mechanics and Thermal Stress in Structural Mechanics, the performance is simulated.
