— A computing platform that works under extreme conditions (> 250 • C and at radiation > 1 Mrad) can be attractive in a number of important application areas, including automotive, space and avionics. Nanoelectromechanical systems (NEMS) switches have emerged as promising candidates for computing in harsh environment. Designing reliable memory specifically(More)
An implantable miniaturized imaging device can be attractive in many clinical applications. They include automated, periodic, high-resolution monitoring of susceptible organs for early detection of an anomalous growth. In this paper, we propose an implantable ultrasonic imager capable of online high-resolution imaging of a region inside the body. A(More)
— Wireless battery charging has been incorporated into an increasing number of commercial electronics with power requirements ranging from a few milliwatts to several hundred watts. With this growing number of deployed devices, there is a necessity to quickly locate and charge them individually. Conventional localization techniques either require(More)
Growing number of important application areas, including automotive and industrial applications as well as space, avionics, combustion engine, intelligent propulsion systems, and geo-thermal exploration require electronics that can work reliable at extreme conditions - in particular at a temperature > 250°C and at high radiation (1-30 Mrad), where(More)
