Guidelines for the Design and Optimization of Wireless Sensors Based on the Modulated Scattering Technique

This paper presents the guidelines for the development and optimization of wireless sensors based on the modulated scattering technique (MST). In particular, this paper is focused on the design and optimization of different MST tag prototypes with different modulation techniques. In addition, it is shown how to obtain the best performance of such sensors in terms of communication range and load efficiency. The preliminary measurements obtained with different experimental tag prototypes demonstrate that these MST sensors are able to measure and to correctly send data without an expensive radio frequency (RF) transmitter or a bulky wired connection. The results obtained show that such sensors could be an interesting alternative to standard RF identifier and wireless sensors.
