“Intelligent Sensory Microsystems for Biomedical Applications”

Intelligent sensory integrated systems acquire sensory data, perform local signal processing, and provide automated feedback to a user or the environment, all on a single physical substrate. The goal of this work is to develop high-throughput, high-integration density and low-power integrated sensory systems that are tailored for implementations on miniature wearable or implantable platforms. High throughput allows for real-time operation in applications with high computational complexity and high data rates. High density of integration yields low cost and small form factor. Low-power designs enable the use of a miniature power supply, wireless power harvesting, or other low-energy power sources. On-chip intelligence enables such integrated systems to autonomously interact with the environment making decisions and taking proper actions without the need for an explicit involvement of a user. A number of microsystem designs with electrical, optical and chemical sensory properties will be presented. Each microsystem employs an electronic microchip fabricated in a CMOS integrated circuit fabrication technology. Examples of the presented microsystem prototypes include an integrated implantable brain-chip interface for electrical neural activity monitoring and automated neurological disorders treatment, and electronic single-chip DNA detection Microsystems employing fluorescent and electrochemical sensory techniques.
