Hello friends welcome to engineering tutorial Blog in today's blog we are going to start a new topic new subject which is very much related to the field of electrical electronics instrumentation basically the sensors and transducers part so it is basically an application of all the concepts of sensors transducers and instrumentation so the topic of discussion is biomedical engineering so the field of biomedical engineering or bioengineering it is the biggest contribution of sensors and transducers to humankind because here the concepts of sensing transduction and instrumentation these technologies are used for the diagnosis of various medical ailments present in human bodies and devising means to preet those elements so it is basically involved in the process of saving human lives so that's why I say that this is the biggest contribution of the field of electronics or electrical engineering the field of sensors transducers and instrumentation to the whole mankind so let's start our discussion with a very basic introduction to biomedical engineering and then we will go deeper and deeper into more and more concepts associated with it so first let us understand what basically the field of bioengineering or biomedical engineering is so it is a discipline that combines and integrates the knowledge of three fields three different domains okay and those three domains are engineering of course basically Electrical and Electronics Engineering as I said sensing transduction and instrumentation and biology and medicine these three domains come together and the meeting point of these three domains gives rise to the field of biomedical engineering okay so it has three main cornerstones the field of biomedical engineering so the first one is of course engineering electrical electronics and instrumentation then biology and then medicine so the main objective of biomedical engineering is first to identify the problems okay what is the objective of biomedical engineering is to first identify the problems to help in the efficient and quicker diagnosis of the medical ailments and then to suggest and devise memes and procedures to plead those elements in an effective way okay so it is a cross-disciplinary discipline it involves the knowledge data and information of the three domains separate domains and it combines the knowledge of the three domains to give rise to various cross-disciplinary activities so it actually takes something from each and every domain biology some concepts of biology will be utilized some concepts of chemistry will be utilized where biochemistry comes into play life sciences physics and some mathematics okay so it involves a little bit of everything okay so the field of bioengineering has has taken something some chunk from each and every discipline okay basic disciplines okay it has something from biology something from physics something from chemistry something from Life Sciences and also some contribution of mathematics so the systematic qualitative and quantitative so as I said bioengineering or biomedical engineering is the meeting point of three main disciplines three main and separate domains which come together and the meeting point is biomedical engineering biology medicine and engineering so the field of biomedical engineering is again subdivided into various sub disciplines okay which are which should be studied separately in order to understand them in a better way and each of these sub disciplines is very vast and exhaustive okay so let us just discuss them in short so here are the various sub disciplines of biomedical engineering okay first one is the bionics and biomedical engineering so this field it basically deals with the design of artificial body parts such as artificial limbs artificial legs and hand arms and various other body parts so it is involved in that so here the concept of instrumentation physics and also mechanics those concepts come into play because we have to utilize those knowledge and data to design the various body parts the artificial body parts in order to replace the damaged parts in the human model next is tissue engineering again it deals with artificial organs and these artificial organs are created by combining some biological material and some artificial man-made material so some portion will be natural biological materials and some portion will be a man-made material okay so where this you can understand with the artificial heart pacemaker machine where other artificial organs are replaced so there this concept comes into play artificial skin so these all of these things which we'll discuss in detail in later parts because if I go into that it would not be sufficient and would take a lot of time so here we are just brushing up the basics okay so the tissue engineering it deals with the artificial organs okay where some component is natural biological and some component is artificial then is genetic engineering it involves with the modification and manipulation of human genes okay gene therapy through DNA recombinant technology genetic modification and genetic splicing these are the techniques that are used for the modification and manipulation of human genes for the treatment of various diseases or for other purposes next is neural engineering of course it the name neural engineering suggested deals with human brain so it involves understanding repairing replacing and enhancing the neural systems so this all deals with human brain here the concept of neural networks fuzzy logic and genetic algorithm also those things come into play then we have is the pharmaceutical engineering here it deals with creation of drugs medicines and various other chemicals for treatment of diseases then we have medical devices so medical devices involves all those equipments tools that are involved in the clinical setup okay so it can be the ultrasonography machine or it can be the laser technology it can be all other medical equipment such as the blood pressure measurement machine stethoscope it can be anything each and every tool equipment that is present or that is used in the clinical setup in the hospitals and medical centers those are dealt and the medical devices field of biomedical engineering then we have the medical imaging so the medical imaging is used for developing technologies to form and to view the inside of the human body which is not visible to the naked eye okay so the various imaging technologies can be through ultraviolet or radiology or laser technology or magnetism so various techniques it can be ultrasonography endoscopy or other imaging techniques that are used it can be through laser sensing so various technologies have come up so all of those are those things they come under medical imaging then we have the last which is clinical engineering so here as I said it deals with the actual installation implementation and application of the various equipments and technologies in hospitals and other clinical settings so it involves teaching the medical professionals how to use those equipments those tools for the diagnosis of the medical elements and then to treat them for the quick recovery and rehabilitation of the patients so here are the various sub disciplines of biomedical engineering and all of these individual disciplines are very much very vast okay it would be very difficult to cover even these sub disciplines we'll separate in detail it would take very long period of time so it is a very vast field the field of biomedical engineering and it is relatively as compared to other disciplines as compared to other subjects it is a relatively new field okay so so it has very much scope for more and more research and more to know more and more in detail about this subject so here we have discussed some of the basic introductory concepts just a basic introduction to the field of biomedical engineering and the upcoming blogs will discuss in detail about the various other associated concepts with it so I hope you like this blog.thaks
