Abstract

Simultaneous Wireless Information and Power Transfer (SWIPT) technology enables Internet of Things (IoT) devices to extend their lifespan by voluntarily harvesting energy. However, the current SWIPT researches primarily focuses on low-band radio frequency (LRF) signals as a source of energy harvesting (EH) and information decoding (ID). In case of LRF signal, with limited spectrum resources, it could be impossible to cope with high-performance communication among massive IoT devices using only RF signals may be challenging. To address this, the article proposes a novel SWIPT scheme, called hybrid frequency SWIPT (HF-SWIPT), based on a frequency division mechanism that employs two different frequencies to access information and energy more efficiently. By leveraging the ultra-wide bandwidth, ultra-high speed, low latency, real-time interaction, and security of Terahertz (THz) communication, information interaction has been achieved in the HF-SWIPT system. Furthermore, RF signal is used for energy transmission due to its higher transmission power and less attenuation in space. Through modeling and investigating, the simulation experiments have been demonstrated that the proposed HF-SWIPT scheme can enhance the performance of IoT devices while reducing their dependence on traditional energy sources.
