Wireless interrogation of passive antenna sensors

Recently, we discovered that the resonant frequency of a microstrip patch antenna is sensitive to mechanical strains or crack presence in the ground plane. Based on this principle, antenna sensors have been demonstrated to measure strain and detect crack in metallic structures. This paper presents a wireless method to remotely interrogate a dual-frequency antenna sensor. An interrogation horn a...

Long-Range Wireless Interrogation of Passive Humidity Sensors Using Van-Atta Cross-Polarization Effect and Different Beam Scanning Technique

This paper presents a method for the remote interrogation of batteryless humidity sensors based on statistical estimations and three-dimensional beam scanning techniques. As a proof-of-concept demonstration, a Van-Atta reflectarray sensor is interrogated with a 24 GHz Frequency-Modulated ContinuousWave transceiver at various reading ranges. The extension of the proposed approach to passive or m...

Wireless Passive Autonomous Sensors with Electromagnetic Transduction

Wireless sensors market is growing very fast these last years tanks to the availability of cheap, small and efficient micro-sensors, batteries, analog and RF circuits, and to the presence of standardized communication protocols. Even if these active sensors are very attractive for a lot of applications, they suffer from weak energy autonomy and they are not compatible with harsh environment. In...

A Study on Passive Crowd Density Estimation using Wireless Sensors

For automatic monitoring systems and user oriented services, crowd density estimation becomes an important research topic. There are existing methods like the camera based crowd density estimation or the RFID based counting systems. However, these methods need deployment cost and enough spaces to set the sensors. In this paper, we therefore present a passive estimation system that could be easi...

Passive Learning from Television

Learning is generally conceived as active and purposive behavior, involv. ing motivation, practice, achievement. Here, the authors focus on "passive" learning, on what is "caught" rather than "taught," and on the processes by which such learning may take place. Passive learning is typically effortless, responsive to animated stimuli, amenable to artificial aid to relaxation, and characterized b...
