Background

The acquisition, processing and analysis of nerve electrical signals and the application of specific functions realized by the induction of electrical stimulation in the nervous system have important significance in the research of neuroscience and the rehabilitation medicine. The acquisition of the electrical nerve signals and functional electrical stimulation require electrodes as interface devices.

The electrodes can be classified into invasive and non-invasive electrodes according to whether the electrodes are implanted into the nerve tissue to be measured. Invasive electrodes can be implanted precisely into the portion of interest of the neural tissue to be measured or stimulated, but can cause minimal trauma to the neural tissue. The non-invasive electrode has no damage to nerves, is attached to or wraps nerve tissues to collect nerve electrical signals or stimulate nerves to generate action potentials, but cannot accurately collect the electrical signals of the target nerves or effectively stimulate the target nerves.

For invasive electrodes, sword-shaped electrodes and Utah electrodes invented by the university of Utah in the United states are common, but the electrodes have the following disadvantages.

1. Is not easy to fix: when the organism moves, the separation is easy.

2. The detection is not flexible: the electrode tip lengths of all channels are fixed and it is not possible to choose whether to insert an electrode and the depth of the electrode according to the specific requirements of the region of interest.
