Electrical Impedance Spectroscopy-Based Defect Sensing Technique in Estimating Cracks
A defect sensing method based on electrical impedance spectroscopy is proposed to image cracks and reinforcing bars in concrete structures. The method utilizes the frequency-dependent behavior of thin insulating cracks: low-frequency electrical currents are blocked by insulating cracks, whereas high-frequency currents can pass through thin cracks to probe the conducting bars. From various frequ...
متن کاملReal-time monitoring primary cardiomyocyte adhesion based on electrochemical impedance spectroscopy and electrical cell-substrate impedance sensing.
The cell-substrate distance is a direct indicator of cell adhesion to extracellular matrix which is indispensable in cell culture. A real-time monitoring approach can provide a detailed profile of cell adhesion, so that enables the detecting of adhesion-related cell behavior. In this work, we report a novel real-time impedance-based method to record the adhesion profile of cardiomyocyte, overco...
متن کاملReview Article: Application of Electrical Impedance Spectroscopy in Bladder Cancer Screening
Introduction Bladder cancer is the most common malignancy in elderly people and most bladder cancers are transitional cell carcinomas (TCC). Bladder pathology is usually investigated visually by cystoscopy and this technique can represent different conditions ranging from simple inflammation to flat CIS. However, biopsies must be taken from the suspected area to obtain diagnostic information. T...
متن کاملArts of electrical impedance tomographic sensing
This paper reviews governing theorems in electrical impedance sensing for analysing the relationships of boundary voltages obtained from different sensing strategies. It reports that both the boundary voltage values and the associated sensitivity matrix of an alternative sensing strategy can be derived from a set of full independent measurements and sensitivity matrix obtained from other sensin...
متن کاملMicro- Electrical Impedance Spectroscopy for Particle Detection
Microfludic devices with integrated electrical detection will enable fast, low-cost or portable sensing and processing of biological and chemical samples. As an inherent property of microfabrication, microelectrical impedance spectroscopy detectors can take advantage of AC electrokinetics for particle manipulation, leading to enhanced sensitivity. Preliminary experiments on particle detection w...
