a method for fabricating an environmentally robust micro - wineglass gyroscope includes the steps of stacking and bonding of at least an inner glass layer and an outer glass layer to a substrate wafer ; plastically deforming the inner glass layer into a mushroom - shaped structure and deforming the outer glass layer into a shield capable of extending over the inner glass layer , while leaving the inner and outer glass layers connectable at a central post location ; removing the substrate layer and a portion of the inner glass layer so that a perimeter of the inner glass layer is free ; and bonding the deformed inner and outer glass layers to a handle wafer . the resulting structure is an environmentally robust micro - wineglass gyroscope which has a double ended supported central post location for the mushroom - shaped structure of the inner glass layer .
