When the need arises to detect various physiological signals of the human body, clothing embroidered with near-field effect patterns can be utilized as a long-term power supply medium to provide power to long-distance transmitters and receivers, creating a wireless power supply system. The proposed system utilizes an optimized parallel circuit to achieve a power transfer efficiency over five times higher than that of the existing series circuit. The power transfer efficiency is increased significantly, even reaching 25.1% when powering eight sensors simultaneously, and can still reach 13.21% even when reducing the sensors to just one. Furthermore, the system is also applicable for a range of 2 to 12 sensors.
When it is necessary to detect various physiological signals of the human body, clothing embroidered with near-field effect patterns can be used as a long-term power supply medium to supply power to long-distance transmitters and receivers to form a wireless power supply system. The proposed system uses an optimized parallel circuit to achieve a power transfer efficiency of more than five times higher than that of the existing series circuit. The power transfer efficiency of simultaneously supplying energy to multiple sensors is increased higher than five times and even more when only one sensor is coupled. When powering eight sensors at the same time, the power transmission efficiency can reach 25.1%. Even when eight sensors powered by the coupled textile coils are reduced to one, the power transfer efficiency of the whole system can reach 13.21%. Additionally, the proposed system is also applicable when the number of sensors ranges from 2 to 12.
