| Abstract: | Based on the implanted sieve microelectroe and the neural signal conditioning circuit which we have finished designing, an integrated system is brought out to pick up the sciatic nerve signal of rats in order to discover the methods of harvesting peripheral nerve information . With microsurgery technology, the microelectrode was implanted into the fascicle of the rat sciatic nerve, The electric signals of the nerve were delivered out by microelectrode and consequently recorded by signal conditioning circuit. The analysis on the waves of electric signalsdelivered successfully and stably brings the finding of nerve actions potentials characteristics, and further validates that the sciatic nerve signal of rats can be recorded with intrafasciclar microelcctrodes. |
