Wireless biomedical implants of the future will interface with biological systems to perform physiological tasks such as vision restoration, reanimation of paralyzed limbs, and chemical sensing. The potential benefit to society will come not only from alleviating human suffering and improving quality of life, but also by reducing the health care costs now directed to assist people with disabilities such as blindness, stroke and spinal-cord injury survivors. Using similar technologies, cochlear implants have already restored functional hearing to over 100,000 deaf patients around the world. The outcomes of the project can also be applied to a variety of other applications such environmental monitoring, security and identification systems. Read moreRead less

Devices based on silicon-on-sapphire processing are potentially faster and are prepared with fewer processing steps than those based on conventional silicon processing technology. However, silicon-on-sapphire films prepared by traditional methods are unsatisfactory due to the high densities of defects they contain. The development of solid phase epitaxial processing has lead to significant increases in performance. This project will characterize the structures of films grown by this new process, and relate them to both the processing conditions and device performance. A greater understanding of the relationship between processing, structure and properties will assist the commercial development of these devices.Read moreRead less
