Huawei has announced a patent for black technology, an electronic device that enables human body communication, which has attracted attention
Huawei unveils the secret technology of "human body communication".
Huawei Technology Co., Ltd. recently made public a so-called"Electronic devices, communication devices and systems based on physical communication"patents. The patent suggests that a device based on bodily communication could be a wireless headset or other wearable device. The device is made up of a device body, a plurality of signal poles and a regulating circuit. the signal electrode is positioned at each part of the device, and the signal electrode forms the path of communication signal transmission with the body of the user; the adjusting circuit is connected to one of the signal electrodes, and the adjusting circuit adjusts the operating parameters of the signal electrodes. Through the configuration of multiple signal poles, the frequency band width of communication is increased, and the setting of the line is adjusted to meet various communication requirements, so as to improve the communication quality and user feelings.
The device is based on the human body and offers a number of advantages. Firstly, a plurality of signal electrodes and the human body form a plurality of different signal transduction pathways, so that each conduction path overlaps and complements each other to achieve a large communication bandwidth. Secondly, by adjusting the setting of each line, the adjustment of each working state under each working state is realized, and the purpose of adapting to various communication requirements and improving communication quality is achieved. For example, a multi-frequency tuning circuit can adjust a signal electrode to one operating frequency point, or one operating frequency point to another, so that the bandwidth of the channel can be expanded. The working conditions of each channel are adjusted by adjusting the aperture to achieve the purpose of adjusting the total capacity and keeping the channel stable. Impedance matching circuitry can reduce reflections and losses in the line. The above characteristics make it have high communication performance and high reliability.
This technology has great practical prospects. For example, two computers can be connected by physical contact, which can achieve high-speed information transmission. During the weighing process of the body fat meter, the data of the human body test can be transmitted to the human body through the link of the human body. In certain situations, such as swimming in water, low-frequency body communication can also be used to transmit information. In this case, it is easier to connect various electronic devices, and the signals transmitted through the body can avoid the dangers of stringing, eavesdropping and theft. Compared with traditional fingerprints, iris, etc., because the physiological characteristics of the human body are more complex and difficult to crack, therefore, based on the interaction between people, it can achieve safer and more reliable detection.
Short-range communication with the human body as the carrier has many advantages. First of all, the scheme adopts a short-range wireless communication mode, using low-frequency signals, which can avoid high-frequency external interference and interference to the body. Secondly, it has the advantages of high safety, high reliability and low energy consumption, and has been widely used in practical applications. The human body is used as the data transmission medium to make the transmission of information more secure and reliable. In addition, the use of human communication technology can expand the communication channels between people, making it more intelligent and convenient.
Personal Summary. Huawei has announced an invention that uses a body-to-body communication device for body communication, which can use a wireless headset or other wearable device for body communication. The invention proposes a method of using a variety of signal electrodes and the human body to form a transmission channel of communication signal, adjusting the line parameters and improving the quality of communication. This technology has the advantages of high efficiency, stability and safety, and can meet the needs of data transmission and intelligent human-machine interaction in various applications. Human communication has a wide range of development space, which will provide more convenience and innovation for the connection of various devices.
