![]() ![]() Her research focusses on creating functional biointerfaces to understand and control biological systems, but also on how to use biological materials or bioinspired strategies to create functional materials. She is a Principal Investigator of MacDiarmid Institute for Advanced Materials and Nanotechnology. Jenny Malmström is a senior lecturer at the Department of Chemical and Materials Engineering at the University of Auckland. His broad experience range from assay development and research into Covid-19 immunity tests to characterization of biopiezoelectricity. Sjoerd Deijs is a bio-molecular scientist with broad experience in biotechnologies. His passion for biology and materials engineering pushed him to pursue higher education in Master of Engineering, where he joined Dr Jenny Malmström's research group to investigate the piezoelectric properties of Bovine tendon collagen and apo-haemoglobin fibrils. For his fourth-year project, he undertook research to investigate the effect of teeth's exposure to coke on its mechanical properties. Ratanak Lay holds a Bachelor of Chemical & Materials Engineering from the University of Auckland. This paper attempts to explain the basis of piezoelectricity in biological and non-biological materials and research involved in those materials as well as applications and limitations of each type of piezoelectric material. Thus, they are useful for many applications such as tissue engineering, biomedical and energy harvesting. On the other hand, biological piezoelectric materials are biodegradable, biocompatible, abundant, low in toxicity and are easy to fabricate. Traditional piezoelectric inorganics show high piezoelectric outputs but are often brittle, inflexible and may contain toxic compounds such as lead. A growing amount of research has been done to investigate the energy harvesting potential of this phenomenon. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back.Piezoelectricity, a linear electromechanical coupling, is of great interest due to its extensive applications including energy harvesters, biomedical, sensors, and automobiles. From the above information, finally, we can conclude that this device is used to measure the distance to an object by using sound waves. Thus, this is all about an overview of an ultrasonic transducer. It will face problems while reading the reflections from small objects, thin and soft objects.This temperature variation may change the ultrasonic reaction. Ultrasonic transducers are sensitive to temperature variation.The disadvantages of these transducers include the following. It can measure in high sensing distances also.In any type of environment, the ultrasonic transducers will work in a good manner.The ultrasonic transducers are not affected by temperature, water, dust or any.These ultrasonic transducers can able to measure in any type of material.Here will discuss the advantages of the ultrasonic transducer. Advantages and DisadvantagesĪny system has advantages and a few disadvantages. By these transducers, they can measure the distance of certain objects to avoid a collision, in production line management, liquid level control, wire break detection, people detection for counting, vehicle detection and many more. In the industrial field, ultrasonic transducers have few important applications. In the medical field, the ultrasonic transducer is having the applications in diagnostic testing, surgical devices while treating cancer, internal organ testing, heart checkups, eyes and uterus checkups ultrasonic transducers are useful. This helps finds the targets, measure the distance of the objects to the target, to find the position of the object, to calculate the level also the ultrasonic transducers are helpful. These are having more applications because of ultrasonic waves. These transducers have many applications in different fields like industrial, medical, etc. The applications of Ultrasonic Transducers are They contact transducers, angle beam transducers, Delay line transducers, immersion transducers, and dual element transducers. (its center frequency is 2 MHz – 7 MHz)įor non-destructive testing, the ultrasonic transducers are again having different types. Phased Array Ultrasonic Transducers – Phased array transducers have a small footprint and low frequency. For in-depth examinations these are preferable. In this type, the piezoelectric crystal is in a curvy form. Standard Ultrasonic Transducers – This type is also called as convex transducers. Linear Ultrasonic Transducers – In this type of transducers, piezoelectric crystal arrangement is linear. There are various types of ultrasonic transducers available based on factors like piezoelectric crystal arrangement, footprint, and frequency.
