Huawei headphones enable human body communication, exposing new black technology!

According to reports, Huawei recently applied for a new patent. This patent involves a new type of electronic equipment. This technology is based on the principle of human body communication (HBC), using the human body as a medium for information transmission to achieve short-range communication. And this method has the advantages of high security, avoidance of environmental interference and low power consumption.

To put it simply: this technology uses the human body as a "communication line" to allow different Electronic devices such as headphones, watches, and mobile phones can transmit data through the human body. Just like when we touch two devices with our fingers, they send information through our bodies.

The patent also mentions a variety of usage scenarios. For example, two computers can be connected through human touch for rapid information transfer. When weighing, the body fat scale and the watch establish a connection through the user's body and transmit body detection data. In addition, in special environments, such as underwater swimming, devices such as headphones and watches can also transmit data through low-frequency human body communication technology. The application of this technology provides a more direct and convenient way for the interconnection between electronic devices.

Xiao Lei believes that this new technology is still very promising and has many technical advantages.


First of all, it uses the human body as a transmission medium, which can reduce the risk of data being intercepted, because the communication range is limited to the human body contact range. Due to the limitation of the communication range, this technology can also better Protect user privacy.


Secondly, it can realize direct physical connection between devices, and devices can be connected without complicated pairing process. Compared to traditional wireless communication technologies such as Bluetooth or Wi-Fi, body-to-body communication may be more energy-efficient.

Furthermore, its application fields are also very wide, for example, it can be applied to wearable devices: smart watches, Health monitoring equipment, etc., data synchronization and transmission between them. There is also rapid data exchange between smartphones and smart ecological devices such as computers and tablets.

Even in the fields of medical health and payment security, this technology is very promising, and patients can transmit key information through their bodies. health data to medical monitoring devices. Another example is the payment scenario that we use every day. Transactions can be completed with a simple touch at the payment terminal, which may be safer and more convenient than today's fingerprint or face recognition.


Nowadays, AI and various smart devices are developing rapidly. If this technology based on human body communication is combined with the Internet of Things (IoT) and artificial intelligence (AI), it can greatly enhance the smart environment. perception capabilities and automated operation levels.


For example, in the Internet of Things, various devices are connected to each other and exchange data through human body communication. Users can interact with smart home devices through simple touch or proximity movements. Or combined with artificial intelligence technology, the system can learn user preferences and behavior patterns based on data collected through human body communication, thereby providing more personalized services. For example, health data collected by smart wearable devices through body communication can be used to adjust the settings of a home health monitoring system.
