Recommended schools: Tianjin University, School of Precision Instruments and Optoelectronics, Biomedical Engineering.
Biomedical engineering includes a wide range of things, one of which is what you call medical device development class.
The biomedical engineering of Tianjin University, although the ranking is not as forward as that of Tsinghua University, which is about 10th in the country, still has some strength. Tianjin University originally favored engineering, especially in the College of Precision Instrumentation (mainly research instrumentation), so the biomedical engineering and instrumentation of the University of Tianjin is very closely linked (formerly known as the medical instrumentation program). However, graduate students will also be divided into many directions, including Professor Li Gang's group is mainly engaged in medical instrumentation, the professor's theory and practice are very strong, but also a very personalized teacher. It is said that many companies specifically go to him to ask for graduate students.
