Electrical impedance tomography (EIT) is an imaging technique that reconstructs the conductivity distribution of an inhomogeneous medium and is capable of monitoring physiological changes in biological materials. This paper focuses on comparison of state-of-the-art regularisation methods in solving the image reconstruction problem in micro-scale EIT for biomedical applications. Since the quality of...
Real-time quantitative imaging is becoming highly desirable to study nondestructively the biological behavior of 3-D cell culture systems. In this paper, we investigate the feasibility of quantitative imaging/monitoring of 3-D cell culture processes via electrical impedance tomography (EIT), which is capable of generating conductivity images in a non-destructive manner with high temporal resolution...
Three-dimensional (3D) tumour spheroids exhibit great potential as an in vitro for pharmaceutical drug testing. Spheroids represent more physiologically relevant systems compared to 2D cell culture models. In this work, MCF7 spheroids are cultured in Corning® spheroid microplates to investigate cell morphology and proliferation. Platinum microelectrodes designed to enable electrical impedance tomography...
Technology evolution has changed users' mindset and preferences in selecting the multimedia player. Recently computers, specifically laptops are among the most favourable choice as the multimedia player leaving behind a real AV System. This is because of the cheap price of a computer and the additional features which are available in a computer. One of the features includes the capability to open...
The core of semiconductor companies is product and technology development to bear the competitiveness. One of the criteria in product development is electrical lab characterization which is crucial in validating the device's electrical functionality without jeopardizing the evaluation quality and ensuring that it is within the product specifications. Typical lab characterization takes longer time...
This paper presents the fabrication and application of a mobile chamber (M-Chamber) for lab bench characterizations that involves high power measurement such as short circuit measurement, current limitation and big load application measurement. Most of the available power supplies in the lab do not have the capability to provide high current; hence, it is needed to apply capacitors in the bench setup...
This paper present the preliminary design of a micro-electromechanical system (MEMS) surface acoustic wave (SAW) resonator as a biosensor using COMSOL. The biosensor consists of a SAW resonator which utilizes mechanical acoustic waves as its sensing mechanism. The preliminary study was performed to verify the functionality and obtain the optimal design parameters for detection of biological cells...
