Latest Patents
One of her latest patents is titled "Low temperature degradation resistant yttria stabilized zirconia." This invention addresses the destructive low-temperature, humidity-enhanced phase transformation of yttria-stabilized zirconia. The invention aims to eliminate low-temperature degradation of yttria-stabilized tetragonal zirconia polycrystalline ceramic (Y-TZP). This class of materials is crucial for packaging small implantable neural-muscular sensors and stimulators due to its high fracture toughness and mechanical strength. By employing post-machining hot isostatic pressing, the average grain size is reduced to less than about 0.5 microns, ensuring the safety of long-term implants.
Another significant patent is the "Method for removing surgically implanted devices." This method involves an integral removal loop or circumferential ring that facilitates the removal of an implantable electronic microdevice without the need for additional surgery. The device can be extracted by pulling it along the surgically created implantation path. Additionally, a radio-opaque tether can be used to locate the implantable microdevice, enhancing the removal process.
