江苏省常州市正衡中学2024年九年级二模英语学习情况调查
It might sound like magic, but in February, a paralyzed(瘫痪的) patient was able to drink water on his own by controlling a special glove with his brain. The glove then acted as his hand. This was a success in brain-machine interface (BMI, 脑机接口) technology made by a team of Chinese scientists and doctors.
BMI refers to creating a connection between the human brain and external devices (外部设备), making communication between the brain and computers. For paralyzed people, BMI can allow them to move and do simple things by themselves.
On Oct 24, 2023, the team put a BMI chip (芯片) in the patient's head. The chip can receive neural signals (神经信号) from the brain.
After three months of home recovery (康复) training, the patient can now use his brain signals to control a special glove powered by air pressure. This helps him do things like drinking water independently.
BMI technology usually means putting chips directly onto the patient's brain. However, this project is minimally invasive (微创的), making sure the patient's brain is not harmed. So it is an important breakthrough. It also uses a wireless power supply(无线电源), so the implanted(植入的) device doesn't need a battery(电池).
Li Yuanning from Shanghai Tech University told CCTV News that BMI is now mainly used in the medical field to improve the lives of people with brain-related problems or speech difficulties.
In China, BMI technology is still in the early stages of research, with no products on the market yet. Some people are worried that tests may influence patients' independence and even who they are. Ethical concerns(伦理问题) related to BMI also need to be addressed. These include whether the patient has a clear understanding of what is going on when they agree to take part in the test.
