She has made significant contributions to the field of actuator and sensor technology, holding a total of five patents. Her work focuses on creating innovative solutions that enhance the performance and stability of various systems.
Latest Patents
One of her latest patents is for a thermally stable actuator/sensor structure. This invention involves a singly or doubly encapsulated actuator/sensor package, where a ceramic actuator/sensor is first encapsulated in a primary material and then in a fiber-reinforced composite material. The combination of materials and ply angles is utilized to control the selection of a composite coefficient of thermal expansion (CTE) and the stiffness of the package. This optimal selection allows for a CTE of zero or one that matches an underlying structural member, maximizing actuation strength in a specific direction. This invention is particularly beneficial for precision structures, enabling them to be designed with low stiffness while maintaining thermally stable actuation forces.
Another notable patent is the spacecraft antenna vibration control damper. This system is designed for an appendage, such as an antenna, that is coupled to a spacecraft platform. The antenna extends from the spacecraft and is supported by guidelines that connect remote portions of the antenna to its base. The invention includes motion control elements within the antenna structure that reduce oscillation settling time relative to the spacecraft. These elements utilize materials whose damping response changes based on the magnitude of an electric or magnetic field applied to them.
