Abstract
Disclosed are a body channel communication method and an apparatus performing the same. An operating method of a transmitter includes obtaining an input signal including biometric information, generating an encoded signal and a control signal by encoding the input signal, generating a return-to-zero (RZ) signal of a biphasic waveform based on the encoded signal, and transmitting the RZ signal through a body channel.
Claims10
An operating method of an implantable transmitter, the operating method comprising:
- obtaining a neural input signal generated by a nerve of a human user, including biometric information;
- generating an encoded signal and a control signal by encoding the obtained neural input signal that includes the biometric information;
- generating a return-to-zero (RZ) signal of a biphasic waveform based on the encoded signal, the RZ signal including a zero signal between each data pulse of the generated RZ signal;
- transmitting, with the implantable transmitter, the RZ signal through a body channel of the human user to a device coupled to the human user;
- and
- performing passive charge balancing based on the control signal.
An implantable transmitter for transmitting signals in a body channel of a human user, comprising:
- a memory configured to store a neural input signal generated by a nerve of the human user, including biometric information;
- a return-to-zero (RZ) encoder configured to generate an encoded signal and a control signal by encoding the neural input signal generated by the nerve of the human user;
- a channel driver configured to generate an RZ signal of a biphasic waveform based on the encoded signal, the RZ signal including a zero signal between each data pulse of the generated RZ signal;
- and
- an electrode configured to transmit the RZ signal through a body channel of the human user to a device coupled to the human user, and
- wherein the channel drier is configured to perform passive charge balancing based on the control signal.
