Features of using the energy of electromagnetic radiation for modern electronics are considered. The structure of the sensor with a receiver of radio emission energy, the methods of use and the field of application of radio emission energy receiverst.
A system of wireless data transfer using energy-independent temperature and strain sensors was developed on radio-frequency identification (RFID) technology and Bluetooth (BT). In case of RFID technology, the radio wave energy conversion is used to provide the power supply of transceiver. This ensures the battery lifetime on one set of batteries up to 5 years and longer. Bluetooth technology enables...
This paper presents the concept and design of a wireless multimodal localization sensor for hybrid localization systems combining vision-based, radio-based and inertial techniques in order to alleviate problems in harsh and complex industrial environments. It supports two radio technologies, 868 MHz UHF RFID and 2.4 GHz WSN, for positioning purposes and communications. The sensor includes LED light...
Electromagnetic energy harvesting has been identified as a free compliment resource to wireless sensor nodes, which essentially prolongs the operating lifespan of built-in batteries. Voltage multiplier is a critical component in energy harvesting circuits and it attracted plenty of efforts in studying how to optimize the design. However, little information was found on how to determine the necessary...
