Abstract: An RF tag circuit including a power storage unit is provided, in which an increase in time required for a voltage change occurring when an impedance is adjusted is reduced. The RF tag circuit is connected to an antenna and a load. The RF tag circuit includes a rectification circuit, a matching circuit, a power storage unit, and a control unit. The rectification circuit rectifies a radio wave received by the antenna and supplies DC power. The matching circuit, of which an impedance is changeable, is interposed between the antenna and the rectification circuit. The power storage unit stores DC power input from the rectification circuit and supplies the stored DC power to the load. The control unit disconnects the power storage unit from the RF tag circuit and adjusts the impedance of the matching circuit such that the amount of the power supplied by the rectification circuit increases.

Abstract: A wireless sensor system includes a sensor tag configured to include a radio frequency tag and a communication device configured to wirelessly communicate with one or more sensor tags. Each of the sensor tags is configured to receive a measurement signal from one or more sensor circuits and stores identification information capable of being distinguished from other sensor tags. The communication device includes a transmission means configured to transmit a command signal to the one or more sensor tags and the command signal includes designation information for designating a sensor target serving as an object. Each of the sensor tags generates measurement data on the basis of the measurement signal if the designation information included in the command signal received from the communication device matches its own stored identification information and starts transmission of a response signal including the generated measurement data when a predetermined response start condition is satisfied.
