Active Implantable Medical Devices (AIMDs) allow the survival and improve the quality of life for millions of patients around the world. The AIMDs are active electronic devices that are implanted into the patient’s body to perform specific critical tasks that the body can no longer perform. To protect the devices from the extremely aggressive environment found in vivo, an impervious, biocompatible barrier material is used to encapsulate the electronic devices. Currently, those barriers are rigid, metallic (e.g., titanium) welded cans. While electronic components were relatively large, these metal cans worked well. However, as electronic components decrease in size and electronic substrates become flexible, conformal, flexible coatings are becoming increasingly desirable. Unfortunately, the use of conformal coatings, such as parylene C, is extremely limited because potential degradation mechanisms in the materials are not understood and there are no accepted standard test procedures that can be used to assess the reliability and predict the lifetimes of such coatings. The Associate would join us in addressing this societally important and scientifically challenging set of goals: (1) to identify failure mechanisms related to thermally, mechanically, electrically, and chemically driven degradation mechanisms in these films; (2) to develop quantitative models to assess reliability and to predict lifetimes under a variety of conditions; and (3) to create new measurement procedures that can lead to standardized test procedures to provide experimental confirmation of the models. Backgrounds in Materials Science, Chemistry, Physics, or Biology would be valuable in this project.
