Title:
HUMAN BODY CHANNEL COMMUNICATION SYSTEM BASED ON CURRENT LOOP CONTROL
Document Type and Number:
WIPO Patent Application WO/2021/007965
Kind Code:
A1
Abstract:
Disclosed is a human body channel communication system based on current loop control. The human body channel communication system is used for the communication of a wearable or implanted apparatus. In the system of the present invention, an energy sending apparatus comprises a pair of electrodes, which are in contact with body tissue, and a signal source, and an energy receiving apparatus comprises another pair of electrodes, which are in contact with the body tissue, and a switching device and a load. The energy-sending apparatus transfers energy to the energy-receiving apparatus via the pair of electrodes, and the energy-receiving apparatus receives energy via the pair of electrodes, such that an energy transmission current loop is formed. The switching device is controlled to be switched on and off by means of a baseband digital signal of the energy-receiving apparatus, so as to switch the energy transmission current loop, thereby realizing data communication from the energy-receiving apparatus to the energy-sending apparatus, and making it possible to save on hardware overheads and reduce system power consumption.
