Summary: Thin film-based flexible strain sensors have advantages for structural health monitoring (SHM). Previous research has developed a flexible strain sensor based on a soft elastomeric capacitor (SEC) and investigated an AC bridge-based method to convert dynamic capacitance changes into voltage signals. However, limitations in AC-bridge balancing, signal amplification control, and calibration have hindered its practical use. This study addressed these limitations with critical updates in hardware and software, resulting in a fully automated high-sensitive capacitive strain sensing system.

Summary: In this work, a passive microwave sensor node called Phavar CraSen is proposed for metallic structural health monitoring. The sensor uses zero-power harmonic generation to isolate the sensor signal from the interrogation signal, and a six-port modulator and capacitive comb-like structures are used to modulate the sensing data. Compared to other sensors, CraSen offers higher robustness and sensitivity for damage detection. It also has advantages in terms of simplicity, low cost, easy fabrication, and measurement, making it suitable for developing smart structures.

Summary: Structural health monitoring (SHM) using wireless sensor networks (WSN) is widely implemented for its low maintenance and installation costs. However, the use of battery-powered sensors in a centralized approach leads to energy consumption limitations. To address this, a distributed algorithm for SHM using wireless passive sensor networks (WPSNs) is proposed, allowing passive sensors to detect and signal changes in the monitored structure.
