 In this paper, we analyze theoretically and experimentally the performance of fiber Bragg gratings as temperature sensors. These sensors have potential applications in monitoring the temperature in aerospace structures and smart structures. Index Terms  Fiber Bragg Gratings, Optical Fibers and Temperature Sensors.

Many electroactive functional materials have been used in smalland microscale transducers and precision mechatronic control systems for years. It was not until the mid-1980s that scientists started integrating electroactive materials with large-scale structures as in situ sensors and/or actuators, thus introducing the concept of smart materials, smart structures, and structronic systems. This p...

Wireless Sensor Networks (WSNs), usually batterypowered, thus very energy-constrained, present energy efficiency as the main challenge. To reduce the overall energy consumption of the network, research community has been tackling power management (PM) techniques on different levels — sensing, communication, computation and energy harvesting. Usually in WSNs the communication consumes most of th...

Smart home technology with situation-awareness is important for seniors to improve safety and security. With the development of context-aware computing, wearable sensor technology, and ubiquitous computing, it is easier for seniors to manage their health problem in smart home environment. For monitoring senior activity in smart home, wearable, and motion sensors-such as respiration rate (RR), e...

S mart-home technology has evolved beyond basic convenience functionality, such as automatically controlled lights and door openers, to provide tangible bene ts. For instance, water ow sensors and smart meters facilitate energy e ciency. IP-enabled cameras, motion sensors, and connected door locks o er be er control of home security. However, a ackers can manipulate smart devices to cause users...
