Abstract
Devices included in a wireless neural interface system are disclosed. According to an embodiment, an internal device of a wireless neural interface system that performs communication through a human body channel may include: bio-electrodes including a first electrode, a second electrode, a third electrode, and a fourth electrode that are attached inside a human body; an oversampling converter configured to detect a biosignal on the basis of the first electrode and the second electrode, and output an oversampling signal by oversampling the biosignal; a wireless signal transmitter configured to encode the oversampling signal on the basis of a human body channel characteristic, and transmit the encoded oversampling signal to an external device, which is connected with the internal device through the human channel, through the third electrode; and a wireless power receiver configured to supply power to the oversampling converter and the wireless signal transmitter in response to a power signal received from the external device through the fourth electrode.
