The scope of this paper is to introduce four such smart materials namely, Piezoelectric materials, Magnetic Shape Memory Alloys, Halochromic materials and Chromogenic Systems. These smart materials would be discussed in the paper along with their practical usage and limitations.
Piezoelectric materials are smart materials that generate voltage when force is applied on such materials. The word ‘Piezo’ is a Latin term that means to press (How it works, 2003). In this manner, such materials are able to change their proportions when force, typically uni-axial compressive force is applied. One is able to identify piezoelectric materials as they produce voltage with the application of force or stress. Another identifying factor is the ability to change shape or become deformed once force is applied. Some examples of Piezoelectric materials are Quartz, Barium Titanate, Lead niobate and potassium sodium tartrate.
The initial usage of this device was found during the Second World War as they were used in SONAR devices. Commonly such materials are used in electro-mechanical devices including speakers and microphones. In microphones, Piezoelectric materials detect audible frequencies. They are also used in welding to serve various purposes such as welding inflexible thermoplastics, metal micro-bonding, steam welding sheets, insertion of metal into plastic etc. They are also used in hydrophones to monitor the heart and the circulatory system (Kutz, 2002).
While the usage of Piezoelectric materials is quite widespread, they are not without their limitations. ‘The most obvious limitations are associated with non-linearity, hysteresis, creep, depoling, electrical breakdown, Curie temperature’ ...Download file to see next pagesRead More

...Chemistry 14 November Materials in Green Cement The largely used construction material globally is Portland cement with an annual production of about 12 billion tones. However, its production utilizes vast amounts of raw materials such as limestone and sand, liberating a ton of carbon dioxide gas per ton of cement produced (Shah & Wang 15). The current focus on sustainable development in concrete technology aims at producing more environmentally friendly cement, which spawns less carbon dioxide and expends less energy. Such environmentally favorable cement is what is referred to as “green cement.” This paper focuses on the advancement of “non-clinker green cement” through the utilization...

...MATERIALS FOR CONSTRUCTION Registration Number: In this case, we are going to compare two structures. We have structure A and structure B. structure A is a 500 slab. This slab is 30 cm thick, so the total volume of the slab is 150. This structure has a tidal zone of San Diego. This is the reason why the structure has constructed using quite a strong mixture. On the other hand we have structure B which is a 800 circular column with a thickness of 50 cm. the total volume for this structure is 400. The analysis period for this structure is similar to that of the above structure. This structure is also exposed to the tidal zones of Miami. The main differences occur in the mixtures that were made and used in the construction...

...Engineering and Construction Materials Markillie highlights the role of digital transition in the manufacturing sector and the third industrial revolution. Manufacturing tools are undergoing changes in a manner that will transform the nature of work in the sector. Past engineers used drills and moulding machines in manufacturing processes. Current engineers, however, apply automated machines in undertaking manufacturing works. Old machines are no longer applicable in the manufacturing process; automated machines outdo the role of old machines. Markillie emphasizes on the introduction of 3D printers among other new automated set of machines applied in manufacturing (1). 3D printers are efficient and simplifies most...
