This summary presents a proof of concept for a passive chipless wireless sensor for temperature range detection. The temperature range information is encoded in a binary format using dual C-like scatterers operating at two different frequencies. The sensing principle is based on resonance shift of the Radar Cross Section (RCS) peaks of the backscattered signal from the two adjacent scatterers. This...
This paper proposes the use of a passive RFID light sensor in a daylight-adaptive lighting system. In such a system, the dimming levels of light sources are adapted to changing daylight such that a desired illuminance distribution is achieved at the place. The system is composed by photo-sensible passive RFID tags used as light sensor nodes and RFID readers connected to a central controller. The use...
This paper is dedicated to a discussion on the concept of the antenna and its evolution since its introduction as a specific device at the end of 19th century. For many decades, antennas were mainly used as transmitting and/or receiving devices. However many additional characteristics of the antenna can be considered in wireless applications. Energy harvesting, environment sensing, backscattering...
