Introduction
Human body communication technology is a transmission technology that uses the human body as a transmission medium to transmit signals. It features low signal leakage, high security, and low latency.
Signal attenuation – characterized by low transmission power and low carrier frequency, resulting in low interference, high security, suitable transmission range, and potential for further improvements.
High degree of miniaturization. Human body communication technology has already been used in several products for medical applications, such as using endoscopic capsules to monitor the digestive system and for testing.
Transmits heart rate and blood oxygen saturation, transmits electrocardiogram signals, monitors muscle contraction or relaxation, fluid hydration and dehydration, and assists in the diagnosis and treatment of fluid disorders.
Disorders, etc.

3.Terms, Definitions and Symbols
The following terms, definitions and symbols apply to this document.
3.1 General Terminology
3.1.1
It handles the interface located between the human body and the human body communication modem, transmitting or receiving electrical signals to or from the human body.
Note. A human body communication semiconductor interface consists of an electrode and an analog front end. The human body communication modem converts data into electrical signals and transmits them to the electrical circuit.
It can either receive electrical signals from an analog front-end or convert them into data. Human body communication semiconductor interfaces are implemented externally or internally to the human body and connect with the surrounding environment.
Equipment integration.
3.1.2
Electrode
A physical structure that attaches to or near the human body to transmit electrical signals between the analog front end and the human body.
Note. The electrodes transmit electrical signals to the non-metallic transmission channel of the human body. Simultaneously, the electrodes transmit the electrical signals received by the human body to the analog front end.
3.1.3
Analogfrontend
Semiconductor integrated circuits that recover original data from received signals transmitted from the human body.
Note. The analog front end includes a power line noise reduction filter, a signal amplifier, a high-pass filter, a comparator, and a clock and data recovery (CDR) circuitry for restoring signal strength.
The raw data is transmitted through a non-metallic transmission channel. Simultaneously, it generates control signals to control the operation of each component in the analog front-end.
3.1.4
Analog front-end circuit components that eliminate power line noise signals in the received signal caused by the human body's antenna function.
Note. See Appendix B for further information on power line noise signal generation.
3.1.5
comparator
Compare the voltage or current magnitudes of two signals and output a signal based on the comparison result, indicating which signal has a lower voltage or current.
Larger analog front-end circuitry components.
