Introduction

Human body communication technology is a transmission technology that uses the human body as a transmission medium to transmit signals. It has the advantages of 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.

GB/T 47240 "Semiconductor Devices - Human Body Communication Semiconductor Interface" is proposed to consist of the following four parts.

---Part 1: General Provisions. The purpose is to specify the general requirements for semiconductor interfaces used in human body communication, including the functional requirements of the interface.

Find the limit value and the working condition requirements.

---Part 2: Performance Characteristics. The purpose is to specify the measurement methods for the electrical performance of electrodes used in human body communication (HBC) semiconductor interfaces.

The method includes the general requirements and functional requirements of the measurement method.

---Part 3: Functional Classification and Operating Conditions. The purpose is to define the functional categories of semiconductor interfaces for Human Body Communication (HBC).

The classification of HBC interfaces includes categorizing them based on contact conditions and defining performance parameters for each type of interface.

---Part 4: Capsule Endoscopes. The purpose is to specify the semiconductor interface for capsule endoscopes using electrically coupled human body communication.

General requirements for electrical performance.

The capsule endoscope's channel transmission uses current coupling, requiring the definition of a common interface for communication with the human body via the capsule endoscope.

Ensure communication compatibility between various capsule endoscopy devices and receiving devices implemented on or inside the human body.
