Applicable situation: some tetrode electrode are distributed around the fiber, and a fine-tuning module is installed on the electrode. After a period of implantation, the electrode and the fiber can be synchronously fine-tuned and stepped to collect new regional signals. This electrode could avoid the problem of no signal acquisition due to glial cells wrapping the electrode wire after implantation for a period of time. This kind of electrode greatly prolongs the validity period after implantation in the body. The adjustable step accuracy is 250um per week which is suitable for use in optical fibers. The electrophysiological signal Spike/LFP is collected at the same time of recording or stimulation, and the microcurrent stimulation of the tissue is performed.
Conventional parameters: commonly used 20/25um diameter nickel-titanium alloy wire, length 5mm/8mm, adjustable length 2mm , one rotation step 250um.
Parameters can be customized according to actual needs
