Significant structural vibration is an undesirable characteristic in helicopter flight that leads to structural fatigue, poor ride quality for passengers and high acoustic signature for the vehicle. Previous Individual Blade Control (IBC) techniques based on piezoelectric actuator schemes to reduce these effects have been hindered by electromechanical limitations of piezoelectric actuators. The...

A commonly used parameter in Structural Health Monitoring (SHM) to ensure the reliability and structural integrity of a lightweight structure is mechanical strain. Usually, strain gauge standard solution measure local The aim this paper through two-dimensional Electrical Impedance Tomography (2D EIT) combination with planar elastoresistive sensor. Thereby, quantitative value conductivity change...

Mortar specimens containing conductive additions (i.e., biochar and recycled carbon fibres – both alone together, graphene nanoplatelets) were characterized from a metrological point of view. Their piezoresistive capability was evaluated, exploiting the 4-electrode Wenner’s method to measure electrical impedance in alternating current (AC); this way, material electrode-material polarization iss...

With the rapidly aging society and increased concern for personal cardiovascular health, novel, flexible electrodes suitable electrocardiogram (ECG) signal monitoring are in demand. Based on excellent electrical mechanical properties of graphene rapid development device fabrication technologies, graphene-based ECG have recently attracted much attention, many with performance been developed. To ...

Structural health monitoring is a developing research field which is multifunctional and can estimate the health condition of the structure by data analyzing and also can prognosticate the structural damages. Illuminating the damages by using piezoelectric sensors is one of the most effective techniques in structural health monitoring. Pressurized equipments are very important components in pro...
