“…One of the most critical aspect of implementing WSNs is the need of simultaneous interrogation of multiple sensors by the same reader, avoiding both interference and collisions [3], [4], [6]. The reader must be able to associate a unique tag to each sensor and the discrimination techniques can be derived from communication theory, according to the following classification: frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), space division multiple access (SDMA), and different combinations of them [10]- [12].…”

This paper is devoted to the feasibility study of a wireless sensing system, mainly based on passive surface acoustic wave sensors, for remote measurement of temperature aboard space platforms. The use of passive sensors is particularly attractive since they need no battery and are robust in extreme environments, as they contain no active electronic circuits. The main objective of this paper is the complete characterization of the wireless system environment, in order to determine the main fundamental limits of this technology from a communication theory point of view. Preliminary experimental measurements are used for defining the main environment parameters, validating some of the theoretical limit computations, and proving the space application feasibility

“…Surface acoustic wave (SAW) sensors could be the enabling technology for wireless space applications as they are passive, radiation hard, operable over wide temperature ranges, small, rugged, inexpensive, and identifiable [2], [3]. Key aspect in system applications of SAW sensors is the ability for simultaneous multiple access, i.e.…”

In this article, the integration of a frequency‐coded radio frequency identification tag with an integrated temperature sensor long lifetime is proposed. It is demonstrated that temperature range can be measured and coded in a tag using tunable stub‐loaded dual‐band resonator that is connected between two orthogonal wideband antennas. The sensor tag emits two different frequencies: the first resonance is used for identification of sensor tag whereas the second frequency is equivalent to temperature. The second resonance is tuned with a varactor controlled by a negative temperature coefficient sensor and its low‐power consumption conditioning circuit. The conditioning circuit modifies the voltage of the varactor and this modifies the second resonant frequency. The resonant structure is studied as a proof of concept. Experimental results at different distances are provided. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2411–2415, 2014
