Wireless power supply implantable neural signal recording and stimulating system

Abstract

The invention relates to a wireless power supply implantable neural signal recording and stimulating system. A wireless power supply system supplies power to other systems, and a nerve recording and stimulating system records or stimulates nerves through microelectrodes; a wireless data link transmission system communicates with the nerve recording and stimulating system through an SPI bus and communicates with a data receiving and file processing system through a mobile phone Bluetooth APP; and the data receiving and file processing system performs Matlab drawable processing on a file. Wireless power supply is adopted, neural signal acquisition and stimulation functions are integrated, the size is small, rejection reaction of an organism due to foreign matters is reduced, free movement of an animal body in an experiment is facilitated, voltage stimulation is accurate, and long-term implantation in the animal body can be realized.

Description

technical field [0001] The invention belongs to the technical field of biomedical electronics, and in particular relates to an implantable nerve signal recording and stimulating system with wireless power supply. Background technique [0002] With the development of biomedical electronics and the rapid development of neuroscience research, some animals are often required to carry out some neural research, which needs to be connected to neurons through equipment to record nerve signals and stimulate nerves and then observe the physiological activities of animals. Studying the electrical signals of nerves and identifying their underlying mechanistic patterns may play an important role in the treatment of a variety of neurological diseases, including epilepsy, Parkinson's syndrome and Alzheimer's disease. Existing nerve recording and stimulation devices are often not the same one. One records and stimulates the other, and they all transmit the collected nerve data to the outsid...

AI Technical Summary

Problems solved by technology

Existing nerve recording and stimulation devices are often not the same one. One records and stimulates the other, and they all transmit the collected nerve data to the outside of the body through a wired connection, and send instructions to the body, and they are wired. The way of power supply or battery power supply will bring a greater risk of infection to the animal body, and it is not conducive to the activities of the animal. The collected data may have little reference value, and, for implantable neural recording and stimulation, There are strict requirements on the size, too large size will not be conducive to implantation in the body
