Organic and polymer-based resistive memory cell sandwiched between two vertically aligned electrodes constitute crossbar memory arrays in which the building blocks, referred to as bit cells, possess two or multiple stable resistance states.1 They are promising circuit elements due to their good scalability and processability, high possibility of molecular design through chemical synthesis, high storage...
Health and usage monitoring (HUMS) as a technique for online test, diagnosis or prognosis of structures and systems has evolved as a key technology for future critical systems. The application of HUMS technology requires a portfolio of reliable miniaturized sensors, capable of delivering "intelligence" on the internal and external environment of a system or structure. This paper proposes...
Health and usage monitoring as a technique for online test, diagnosis or prognosis of structures and systems has evolved as a key technology for future critical systems. The technology, often referred to as HUMS is usually based around sensors that must be more reliable than the system or structure they are monitoring. This paper proposes a fault tolerant sensor architecture and demonstrates the feasibility...
Transient space charge within polyethylene has been simulated based on a bipolar charge transport model with a constant mobility. Initial results are in good agreement with those previously reported. To further develop the model, two types of field-dependent carrier mobility: power-law mobility and Poole-Frenkel mobility are considered in the charge transport process. Various space charge profiles...
This paper reports on the investigation into space charge characteristics at interfaces of multi-layer polymeric materials. Planar low density polyethylene (LDPE) samples were used in this study. DC voltage up-to 10 kV was applied to the sample and space charge measurements were taken using the pulsed electro-acoustic (PEA) technique. Experimental results indicated that the electrode interface plays...
