Recently, “Tangential Displacement Normal Normal Stress” elements were introduced for small-deformation piezoelectric structures. Benefits of these elements are that they are free from shear locking in thin structures and volume locking for nearly incompressible materials. We extend these elements to the large deformation case for electro-active po...

Synthetic biology has allowed us to generate bioproducts from our natural environment. Modern natural sciences have been created to acquire technological mastery over natural processes, resulting in a never-ending stream of new items and technology being introduced into current society, enhancing living comfort and raising overall human well-being. As a result, this technological advancement has unintentionally resulted in increased fossil fuel use, population expansion, urbanization, and deforestation, all of that put further strain on future resources owing to pollution, resource depletion, and biodiversity loss. The study aims to analyse discussions over digital architecture and new industrialization as well as the impact of biotechnology on architecture, interior design, and more especially, the usage of living or semi-living materials in our built environment. Furthermore, as a material and technical innovator, a strong understanding of the disciplines of computational data generation, 3D printing, and digital manufacturing is critical. In addition, bio-augmented design investigates our current interaction with nature. It is the scientific study of life and living entities, ranging from simple organisms to the most sophisticated. The study demonstrates bio-fabrication, which involves designing with living beings where biosynthesis is replacing traditional manufacturing, plants which manufacture items, microbes which develop new materials, and energy-efficient bio designs. Furthermore, these new composite materials provide a vision into the near future when synthetic biology may be used to assist us in designing and building the built environment with higher performance and lower environmental impact than traditional architectural, as well as interior design approaches. The research highlights the shift from nature-inspired design to nature-integrated design. Many recent biological trends identify bio-futuristic design as a paradigm shift in interior design, creating a distinct interface for tectonic and ecological materials between nature and design, as well as an orientation towards healthier structures. Finally, the study concludes that using 50 E-ISSN 2812-4928, P-ISSN 28125339 (https://msaeng.journals.ekb.eg//) living materials, probiotic design, bio-fabrication, bio-receptive design, and bio-augmented design can help to create a sustainable environment in interior design.
... Since such man-made structures deteriorate over time, a bridge, for example, is designed to have an average life cycle of 60-80 years, the continuous, fast, accurate, and real-time monitoring of such structures is necessary in order to not only to prevent extensive damage, but also, to prevent major accidents. Over the last decades, civil engineering has been moving towards the construction of intelligent structures, in which sensors are arranged on the surface of, or embedded in, such structures, so that healthy monitoring of active vibration control, temperature and lighting, are performed in real time [1][2][3][4][5]. In this sense, piezoelectric sensors have proven to be one of the most efficient for monitoring structural health in the area of civil engineering [5][6][7][8]. ...
0–3 Cement-based piezoelectric composites were produced. It was verified that not only the piezoelectric properties of the composites, but also the influence of piezoelectric phase in the cement paste curing process. The results showed that the final piezoelectric and dielectric properties of the composites depend mainly on the interfacial microstructure between the matrix and the piezoelectric insertion. DC conductivity and impedance spectroscopy measurements showed a high sensitivity to the identification of retard hydration process or phase transformations. Piezoelectric properties show ageing fluctuations, attributed to the cement curing process which promoted unstable dipoles at the same time that it promoted piezoelectric phase constriction.

Smart structures are those structures that are capable of sensing and reacting to their environment in a predictable and desired manner, through the integration of various sensors, power sources, signal processors and control mechanisms etc. Earthquakes related vibration control is a modernized and most commonly used system for smart buildings. The scientific utilization of smart structural components in the design, construction and preservation of infrastructures needs attention in civil engineering aspect. One of the most promising environment friendly vibration control device is shape memory alloy (SMA) dampers. In this study, a G+4 storey building has been modeled and the performance of the building is under different earthquakes are evaluated using SMA dampers. SMA dampers are installed in the first storey of the frame. The time-history analysis results for both the controlled and the uncontrolled frames under different ground acceleration excitations shows that the SMA dampers are capable of mitigating floor displacement. The results also indicate that the controlled frames vibrate around the initial position, and the SMA damper shows no residual deformation after ground excitation.

and maintain. Vibration and movement measurement systems based on Internet of Things (IoT) for transport infrastructure are being more and more relied on research and development. However, choosing low cost and reliable INS sensor with a suitable data processing method to have good accuracy, coverage, and performance often is a challenging problem. In this article, we design and create measurement modules using a 9-DOF MEMS INS sensor for capturing data, processing and transmitting them by XBee wireless platforms to capture vibration and movement from the supervised objects. The station will plot the data in the real-time chart on website monitoring. We have processed the calibration to remove the error data of IMU sensor due to the impact of internal and external factors, drifting data and offsets. And some experiments have been performed for the purpose of employing a wireless sensor network for transport infrastructures in smart cities.
