US developed an electronic microchip to replace the electrode sheet to connect the nerve tissue with the controlled prosthesis
Release date: 2007-02-02
U.S. develops electronic microchips to replace electrode pads to connect nerve tissue with controlled prostheses. Researchers at the University of Pennsylvania recently announced that they have connected human nerve tissue to electrodes and developed new technologies for connecting neural tissue to controlled prostheses.
The researchers found a portable living tissue that was connected to the electrode and implanted the other end of the nerve tissue that was not connected to the electrode into the patient's nervous system to ensure that it delivered a signal to the electrode.
The researchers put forward the idea of ​​transmitting information to the prosthesis with undamaged nerve tissue. The key is to ensure the two-way connection between the prosthesis and the brain. That is to say, the nerve signal from the brain must be converted into the motion of the prosthesis, and the prosthesis Sensing system signals, such as temperature and pressure, should be ensured to be fed back to the brain.
It is reported that the researchers used the method of cultivating nerve cell processes to develop the above-mentioned mixed nerve tissue. Since the nerve cell process can stretch to the required length between the two electrode sheets, the researchers replaced one of the electrode sheets with an electronic microchip in the development.
Currently, researchers are testing the electrical activity of the neurons they develop, and plan to use it to restore the muscle motor function of animals with damaged nervous system in the experiment, and then carry out clinical experiments on neurons. —— Information from: Kexun Information Center
