The new developments in medical electronics, aims to facilitate significantly the process of acquisition of biomedical signals, in order to achieve a correct approach when developing diagnostic or medical monitoring, to optimize the required care process and sometimes to reduce the cost of such processes.The development of biomedical devices allowing the acquisition of various signals for subsequent monitoring and analysis in real time.
Just the way wherein bio-material based devices are getting shaped as synthetic organs, devices research in medical electronics is challenged by the need to develop synthetic systems capable of bio-signal recognition , processing, response instructions translated back as bio- signals recognized by brain. Objective will be to support quality of life , wherein in a human body ,sensors are working, transmission is working but processing alone is not functional kind of situation faced by brain and such functions are to be taken over.
Dear Badir,
I would just go in details about a market of medical equipments. I would like to mention market players, medical equipment and signal base medical equipment used for patients and physicians and surgeons for their applications and research as well. Semiconductor, engineering(mechanical and electronics), physics, optics and solid state electronics play an important role in the development of medical equipment.

Ltd, STMicroelectronics N.V., NXP Semiconductors N.V., Medtronic PLC., Cypress Semiconductor Corporation, Analog Devices, Inc., On Semiconductor Corporation, Siemens Healthcare Private Limited, and Philips Healthcare Pvt. Ltd.
With advancement in technology, newer medical electronics devices are emerging in healthcare which is also expected to boost growth in medical electronics market. Moreover, factors such as increased market penetration rate of portable medical devices, increasing trend of remote patient monitoring, and high availability of electronic components such as memory devices, display technologies and microcontrollers are expected to create growth opportunities for medical electronics market.
Electronic devices are increasingly used for therapy, diagnosis, and rehabilitation in the field of medicine. Electromechanical equipment and medical electronics have become indispensable for providing better services to patients. Medical equipment and instruments are used for medical applications such as research, diagnosis, therapy, anesthesia control, surgery, and cardiac control. It integrates medicine and environmental science with engineering practices and theories. Semiconductors have become an integral part of medical electronics equipment for reducing the cost which is changing the affordability of equipments. Rapid advancement in IT and increasing health care consciousness has accelerated the scope for medical electronics market. Advanced technology in medical electronics include telehealth in intensive care unit (ICU), emergency department (ED) and hospital ward and skilled nursing facility (SNF). With the advent of digital stethoscopes, digital X-ray systems and handheld smart phone-sized ultrasound systems, conventional medical devices have evolved to aid medical electronics market.
Biomedical signals obtained from the human body can be beneficial in a variety of scenarios in a healthcare setting. Physicians can use the noninvasive sensing, recording, and processing of a heart’s electrical activity in the form of electrocardiograms (ECGs) to help make informed decisions about a patient’s cardiovascular health. A typical biomedical signal acquisition system consist of sensors, preamplifiers, filters, analog-to-digital conversion, processing and analysis using computers, and the visual display of the outputs. These signals, intelligent methods and computer algorithms can be developed for analysis of the signals. In the second generation, with the implementation of the Fast Fourier Transform (FFT) technique, many spectral domain approaches were developed to get a better representation of the biomedical signals for analysis. For example, the coherence analysis of the spectra of brain waves also known as electroencephalogram (EEG) signals have provided an enhanced understanding of certain neurological disorders, such as epilepsy.
