The Internet of Things (IoT) is a rapidly emerging application space, poised to become the largest electronics market for the semiconductor industry. IoT devices are focused on sensing and actuating of our physical environment and have a nearly unlimited breadth of uses. In this paper, we explore the IoT application space and then identify two common challenges that exist across this space: ultra-low...
In- and outboard plasma facing components (PFCs) of Korea Superconducting Tokamak Advanced Research (KSTAR) have been fully installed in 2010 for D-shaped diverted plasmas. Before the start of plasma operation, the PFCs were baked up to 200 by hot nitrogen gas circulation system to remove impurities including water. The surface temperature of the PFC tiles was monitored by 200 thermocouple...
We report the hydrogen sensing properties of a sensor using TiO2 nanotube arrays. The TiO2 nanotube arrays were fabricated by anodization on titanium foil, in an electrolyte containing 0.5 wt% hydrofluoric acid mixed with water, the electric potential being 15V. TiO2 nanotube arrays were annealed at 600 Celsius for 1 h. The sensors were equipped with platinum electrodes. These two were connected with...
