Results for tag: "Radio Frequency Energy Harvesting"

Radio Frequency Energy Harvesting (RFEH) refers to the process of converting energy from radio frequency (RF) waves into electricity, which can then be stored and used for various applications. This is particularly relevant for powering small devices and sensors within the Internet of Things (IoT), wearable electronics, medical devices, and other low-power applications. The energy storage aspect of RFEH is crucial, as it allows the captured energy to be stored in small-scale batteries or capacitors for later use. This technology enables a self-sufficient power supply, reducing reliance on external power sources or frequent battery replacements, which is advantageous for remote or inaccessible locations. RFEH systems typically include an antenna, a rectifying circuit, and a storage component. The antennas capture the ambient RF radiation, which is subsequently converted into DC voltage by the rectifiers. The energy is then stored for use by the connected device. Developments in RFEH have led to the emergence of companies specializing in various aspects of the technology. Some notable players in the RF energy harvesting market include Powercast Corporation, which provides wireless power solutions and RF energy harvesting technology; Texas Instruments, known for its semiconductors and electronics, also provides energy management and storage solutions; Fujitsu, offering a range of technology products, including RFEH technologies; and e-peas, a company specializing in energy harvesting and processing solutions. These companies, among others, are contributing to the advancement of energy harvesting and storage technologies by developing more Show Less Read more
