| Popis: | An implanted microelectrode is the first piece of hardware in the extracellular neural signal‐recording pathway. This work presents a simple, flexible and economical microwire array electrode for extracellular cortical recordings. The materials include Teflon insulated tungsten microwires, a printed circuit board pattern, a flexible flat cable and connector and viscose epoxy A+B. The proposed procedure is relatively simple, even for a novice worker to implement in‐house. These main steps include design and sculpting a printed circuit board, straightening microwires, connecting printed circuit board patterns, arraying and soldering microwires and packaging the microelectrode. In this study, we apply electrochemical impedance spectroscopy to measure the impedance and the phase between the electrode and the electrolyte, and then to obtain an equivalent circuit. The presented microwire array electrode is successfully adopted to record an extracellular cortical signal. The proposed microwire array ele... |
