Summary: This article investigates the performance of curved piezo transducers in energy harvesting and structural health monitoring (SHM) in reinforced concrete (RC) structures. The study compares the open-circuit voltage, power developed under impedance matching conditions, and power storage potential of curved and straight configurations. Results show that curved piezo transducers exhibit better performance in both energy harvesting and SHM. Finite element analysis and numerical simulations also provide insights into the optimal bend angle, position, and thickness for energy harvesting in RC structures.

Summary: Electrical impedance spectroscopy (EIS) is a powerful tool in biomedical research, but single-channel systems lack spatial resolution. Researchers have developed a low-cost multichannel setup using a microelectrode array (MEA) to map cell distributions in a fluidic environment. The MEA, connected to programmable multiplexers and an analog front-end module, produced impedance maps that matched optical images of yeast cell distribution in a reservoir.

Summary: This study presents a novel approach to assess the setting time of concrete by using the electro-mechanical impedance (EMI) sensing technique. The method involves continuous monitoring of EMI changes by embedding a piezoelectric sensor directly in the concrete. Compared with the conventional penetration resistance test using mortar samples extracted from the concrete, the EMI sensing technique showed a significantly lower time deviation rate of the setting time, highlighting its effectiveness and potential for improved evaluation of concrete setting time.

Summary: This paper investigates soil moisture loss monitoring based on lead zirconate titanate (PZT) transducer using electro-mechanical impedance (EMI) technique. Experimental results indicate that the peak frequency in the conductance signatures shifts to the right as water evaporates, and the corresponding peak magnitude decreases with continuous soil moisture loss. Statistical metrics analysis demonstrates the feasibility and reliability of using embedded PZT transducer for monitoring moisture loss in cohesive and sandy soils. This study also serves as a proof-of-concept for the performance of EMI technique in soil moisture content monitoring.

Summary: In recent years, low-cost accelerometers have gained more attention in Structural Health Monitoring applications. Existing accelerometers based on Arduino or Raspberry Pi technologies have some limitations. In this study, a new low-cost triaxial accelerometer based on Arduino technology (LARA) is proposed to address these limitations. Laboratory tests show that LARA has a low noise density and high frequency sampling speed, and its application in eigenfrequency analysis has reliable results compared to high-precision commercial sensors.
