Passive Resonant Sensors: Trends and Future Prospects
The choice of topic was « Passive Resonant Sensors: Trends and Future Prospects » . The review focuses on technologies that exploit the « resonance phenomenon » that occurs with all types of waves: acoustic, electromagnetic and optical. The sensors considered include acoustic, magneto-elastic and electromagnetic transducers. They are presented through their relevant technological aspects and their main advantages, in particular their integrability in embedded systems and/or their energy autonomy requirement. The use of these resonant sensors is illustrated in a wide variety of applications (Fig. 1), ranging from environmental, structural, and food packaging monitoring, to wearable or implanted sensors of physiological parameters in health-related, Internet of Things (IoT), and Industry 4.0 applications.
