Biomedical electronics and information technology is a branch of biomedical engineering, and biomedical engineering (BME) is a marginal discipline that combines science, engineering and medicine, and is the product of the penetration of various engineering disciplines into biomedical biomedicine. It is a comprehensive and high-tech discipline that uses the principles and methods of modern natural science and engineering technology to study the structure, function and interrelationship of the human body at multiple levels from the perspective of engineering, reveal its life phenomena, and provide new technical means for disease prevention and treatment. People of insight believe that with the continuous development of natural sciences in the new century, the prospects for the development of biomedical engineering are immeasurable.

The discipline of biomedical engineering is a highly comprehensive interdisciplinary discipline, which is its biggest feature.

Compared with biomedical engineering, biomedical electronics and information technology may be more focused on electronic and information technology, that is, information engineering, and biomedical engineering covers a wide range of fields.

The human body is a huge bioelectric field, and the organs, tissues and cells of living organisms undergo potential and polar changes during life activities. Biological electric wave vibration is the result of a kind of physical, physico-chemical changes in the process of life activities, which is the manifestation of normal physiological activities, and is also the most basic basic feature of biological composition, growth and development.

Almost all biological activities are related to the electrical energy of living organisms. As early as more than 2,000 years ago, human beings discovered the fact that the animal body was electrified, and used the bioelectric ** psychosis of electric rays, since then, human beings have never stopped studying their own bioelectricity, and with the development of science and technology, it is becoming more and more clear.

In 1920, Danish scientist Sven Ingefa discovered that an external electric field causes changes in animal neurons.

In 1924, Dutch physiologist Wilhelm Einthofen was awarded the Nobel Prize in Medicine for his successful recording of the frequency of cardiac bioelectric waves and the invention of the "electrocardiograph".

In 1950, "Biomedical Electronics" became an independent discipline and rose rapidly in developed countries such as the United States and the United Kingdom.

In 1952, British physiologist Hodgkin was awarded the Nobel Prize in Physiology for recording the changes of radio waves across nerve cell membranes for the first time.

In the same year, the famous American book "The New Revolution in Medicine, Making the Impossible Possible, Electric Current Healing, Human Beings Will Have No Terminal Disease" mentioned for the first time: "If human beings want to stay away from terminal diseases, they can only be completed by applying "Biomedical Electronics". ”

In 1958, Rune Elmqvist invented the first pacemaker.

In the 70s of the 20th century, the first generation of islet chargers and stabilized chargers were born. It allows many patients with diabetes and hypertension to completely get rid of the pain of injections and medicines in just 90 days, completely subverting the traditional concept of diabetes and hypertension.

At the beginning of the 21st century, "Biomedical Electronics" began to be applied to aeromedicine, plant physiology and bionics.

In 2009, Ludinggong International Health Consultant Management Co., Ltd. successfully developed a quantum bioelectric energy product, which completely kept patients with chronic metabolic imbalance diseases such as hypertension, diabetes, and cardiovascular and cerebrovascular diseases away from drug damage.

Biomedical electronics applies electronic technology to solve problems in biomedicine, and starts from the particularity of life itself, to study the theories, methods and means of electronic science in biomedical applications, such as detection, processing, display and recording of biomedical signals.
