Medical ultrasound (also known as diagnostic sonography or ultrasonography) is a diagnostic imaging technique, or therapeutic application of ultrasound.It is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs.Its aim is often to find a source of a disease or to exclude pathology. It has been proposed for a variety of applications in biomedical field. It is likely that the ultrasound community will conduct more research on 2D array design, fabrication, and the associated imaging algorithm development within the next decade or so. For the last four years the Laboratory of Biometrology of PUC-Rio has been working in the development of magnetic field transducers to be used in biomedical applications — especially in the three-dimensional localization of needles inserted in the human body and in the measurment of arterial pulse waves. BioMEMS application areas include biomedical transducers, microfluidics, medical implants, microsurgical tools, and tissue engineering. Application of Biomedical Sensor and Transducer in the Elderly Tamura, Toshiyo; Abstract .

Passive Transducers: It converts one form of energy into another form with the help of an external power source. Applications of piezoelectric material for biomechanical power generation instead of battery replacement results in avoiding surgeries are discussed in this section. When light or any other radiation of wavelength falls on the metal or semiconductor surface, it ejects electrons.

On the other hand, low cost transducer arrays are increasingly in demand by the portable ultrasound devices, which can be a smart phone-based ultrasound imaging device (e.g., butterfly4) or a fingerprint device in a smart phone [29] or part of a wearable health care system. In general, the process of transduction involves the conversion of one form of energy into another form. medical imaging applications. Transducers in the frequency range of 100 MHz up to 1 GHz are primarily used in biomedical research for low penetration applications. It is used for detecting the movement of muscles which is called acceleromyograph. The strain gauge, photoresistor, photodiode, phototransistor, and thermistor come under resistive type passive transducers. Also, US practical uses in medical therapy is shown.
