This article is mainly about the related knowledge about biomedical engineering that I learned in the introduction course of biomedical engineering this semester. This paper introduces the general situation and subject characteristics of biomedical engineering, expounds the research fields of this subject, and emphatically introduces the present situation and development trend of biomedical engineering. Finally, I wrote down my understanding and learning methods of this subject and encouraged myself to study this subject hard.

Keywords: current situation and development trend of biomedical engineering research field

Introduction to biomedical engineering

1. discipline overview

Biomedical engineering is a new frontier discipline, which combines the theories and methods of engineering, biology and medicine, studies the state changes of human body system at all levels, and uses engineering technology to control this change, with the aim of solving related problems in medicine, ensuring human health and serving the prevention, diagnosis, treatment and rehabilitation of diseases.

2. Discipline characteristics

(1) crossing: it is the product of the high crossing of various disciplines and the combination of the new era; This is an urgent need for the modernization of life sciences (biology and medicine); It is the inevitable result of the rapid development of modern science and technology.

(2) Dependence: it has not yet formed its own independent basic theory and knowledge system (different from traditional disciplines), which is based on the integration of interdisciplinary knowledge; Lack of eternal research topics and internal central objectives changes with the development of interdisciplinary subjects and the needs of application objects.

(3) Complexity: covering a wide range of knowledge, involving almost all basic theories and knowledge systems of natural science and technology; Relevant research institutions, professional education, enterprise manufacturers and marketing can only set foot in some of them, but not the overall situation.

(4) Service: focusing on applied basic or direct applied research and aiming at its final application in the biomedical field; Provide modern tools for the innovative development of life sciences and new equipment for the modern development of medical and health undertakings (support biomedical engineering industry).

Second, the research field.

Biomedical engineering is the combination of engineering, biology and medicine. The combination of any engineering discipline with biology and medicine belongs to the category of biomedical engineering, so the research field of biomedical engineering is very extensive and developing continuously. At present, there are eight mature areas as follows:

1. biomechanics

2. Biological materials

3. Modeling and simulation of biological system

4. The application of physical factors in treatment and their biological effects.

5. Biomedical signal detection and sensors

6. Biomedical signal processing

7. Medical imaging technology

8. Artificial organs
