Networked systems of tiny wireless and sensing-enabled devices continue to give birth to a host of new applications that range from medical sensors for image-guided surgery, to distributed image-based surveillance of remote areas for security or environmental reasons. Such applications mandate new requirements in terms of size of the devices as well as the bandwidth required. Extreme requirements for small size packaging of the devices are obvious for many applications including biomedical ones. Fully integrated sensor modules that are capable of harvesting energy, sensing the environment and communicating with other sensors or base stations are becoming a necessity. Despite the development chips for these systems, there continues to be a need for improved implementations of micro-scale detection and processing systems for further convenience, scaling and portability. These systems would include a sensor module (mostly in mems), attached to analog front end circuitry, an analog to digital converter and a wireless communication module. We will present the research conducted at KAUST addressing many of these components. A flagship project demonstrating these concept is a single chip implantable wireless sensor system for Intraocular Pressure Monitoring (IOPM). This system-on-chip (SoC) is battery free and harvests energy from incoming RF signals, consumes 513 W of peak power and when implanted inside the eye, it can communicate over a distance of more than 15 cm.
Dr. Salama received his bachelor's degree with honors from the Electronics and Communications Department at Cairo University in Egypt in 1997, and his master's and doctorate degrees from the Electrical Engineering Department at Stanford University in the United States, in 2000 and 2005 respectively. He was an assistant professor at RPI between 2005 and 2009. He joined King Abdullah University of science and technology (kaust) in January 2009 and was the electrical engineering founding program chair till August 2011. His work on CMOS sensors for molecular detection has been funded by the National Institutes of Health (NIH) and the Defense Advanced Research Projects Agency (DARPA), awarded the Stanford-Berkeley Innovators Challenge Award in biological sciences and was acquired by Lumina Inc in 2008. He is the co-author 100 papers and 10 patents on low-power mixed-signal circuits for intelligent fully integrated sensors and non linear electronics specially memristor devices. He is a senior member of IEEE.
