Biomedical engineering (BME) combines the principles of physics, chemistry, mathematics, computer and engineering, and is engaged in the research of biology, medicine, behavior or hygiene; Put forward basic concepts, generate knowledge from molecular level to organ level, and develop innovative biological products, materials, processing methods, implants, instruments and informatics methods for disease prevention, diagnosis and treatment, patient rehabilitation and health improvement.
Biomedical engineering is a new frontier discipline. It combines the theories and methods of engineering, physics, biology and medicine, studies the state changes of human body system at all levels, and uses engineering technology to control this change. Its purpose is to solve medical problems, safeguard human health and serve the prevention, diagnosis, treatment and rehabilitation of diseases.
One of its branches is biological information, chemical biology and so on. He mainly studies biology, computer information technology and instrumental analytical chemistry. The development of microfluidic chip technology provides new technical prospects for biomedical engineering of medical diagnosis and drug screening, as well as personalized and translational medicine. Chemical biology, computational biology and microfluidic chip are all systems biotechnology, so it will move towards a unified future with system bioengineering.
Biomedical engineering rose in the 1950s, and it has a very close relationship with medical engineering and biotechnology. It has developed rapidly and has become one of the main areas of competition among countries in the world.
Biomedical engineering, like other disciplines, is determined by scientific, technical, social and economic factors. This term first appeared in America. 1958, the International Federation of Medical Electronics was established in the United States. 1965, the organization changed its name to the International Federation of Medical and Bioengineering, and later became the International Society of Biomedical Engineering.
Biomedical engineering has not only good social benefits, but also good economic benefits, and has a very broad prospect. It is one of the high technologies that countries are scrambling to develop in the new era. Taking 1984 as an example, the market size of biomedical engineering and systems in the United States is about 1 1 billion dollars. The American Academy of Sciences estimates that by the year 2000, its output value is expected to reach 40-654.38+000 billion US dollars.
Biomedical engineering is based on the development of electronics, microelectronics, modern computer technology, chemistry, polymer chemistry, mechanics, modern physics, optics, ray technology, precision machinery and modern high technology, and developed under the condition of combining with medicine. Its development process is closely related to the development of high technology in the world, and almost all high-tech achievements, such as aerospace technology and microelectronics technology, have been adopted.
