The use of the Internet of Things in buildings has become increasingly important. Meanwhile, sensors and actuators play a very important role. With the help of sensors, various data of residents' environment and behavior can be obtained and various parameters can be controlled through actuators. Data from the presence, measurement and decision making of the components of this structure in a building can be used to model and predict the behavior of residents with methods of machine learning, data mining and artificial intelligence such as deep learning and Gaussian processes, helping to achieve the goal of residents' comfort and energy saving.In the desired structure, the sensor- actuator... 

The current research focuses on preparing conductive hydrogels with combined shape memory and actuating under the effect of external stimuli. Two studies were conducted in which hydrogels simultaneously showed shape memory and actuating behaviors. The magnetic carrageenan-based double network hydrogels were prepared in the first part. The presence of magnetic nanoparticles not only strengthened the mechanical properties, but also induced shape memory properties under a magnetic field. These hydrogels had good electrical conductivity and showed successful performance as strain sensors. The hydrogels performed well in simple and complex shape memory experiments in response to the temperature....
