A significant impediment to implementing micro- and nanoswitch technology is that the small contact areas (10−4 to 102 µm2) and low forces (nano to micronewtons) render the surfaces inherently susceptible to contamination, which increases their contact resistance. In this work, we report on the formation of carbonaceous tribopolymer (TP) in microswitches under controlled environmental conditions in...
This paper presents the methodology for determining the electrical resistance of polygonal pole for high voltage electric power lines. Icosahedral pole was considered where its total electrical resistance is combination of the electrical resistances of the pole's material and the resistance of the slipping contacts between different pole's parts. Material resistance and also coefficient of contact...
This paper reports electromechanical analysis of basic conductive textile structures designed for wearable sensors. Conductive textile structures usually exhibit two types of resistance: length resistance and contact resistance. Firstly electrical and mechanical properties of unstressed conductive yarn were investigated under practical use conditions. After that three experiments were conducted to...
With fast development of electronic packaging, the conductive adhesives were widely used in surface mount and chip interconnection. As an alternative to solder, it has many advantages, such as low processing temperature, less environment contamination and fine pitch capability. However, conductive adhesive joining technology also simultaneously faces a lot of challenges. The major problem of current...
Surface roughness has many effects in contacting engineering surfaces and electrical connectors are no exception. In connectors, the roughness on the surfaces causes added electrical resistance (known as electrical contact resistance (ECR)). This work presents a new method for modeling ECR while considering the multi-scale nature of surfaces in the contact mechanics and electrical resistivity theory...
