Pencil Drawn Strain Gauges and Chemiresistors on Paper
Pencil traces drawn on print papers are shown to function as strain gauges and chemiresistors. Regular graphite/clay pencils can leave traces composed of percolated networks of fine graphite powders, which exhibit reversible resistance changes upon compressive or tensile deflections. Flexible toy pencils can leave traces that are essentially thin films of graphite/polymer composites, which show...
متن کاملPencil It in: Exploring the Feasibility of Hand-Drawn Pencil Electrochemical Sensors and Their Direct Comparison to Screen-Printed Electrodes
We explore the fabrication, physicochemical characterisation (SEM, Raman, EDX and XPS) and electrochemical application of hand-drawn pencil electrodes (PDEs) upon an ultra-flexible polyester substrate; investigating the number of draws (used for their fabrication), the pencil grade utilised (HB to 9B) and the electrochemical properties of an array of batches (i.e, pencil boxes). Electrochemical...
متن کاملMimicking Hand-Drawn Pencil Lines
We provide a system that will serve as a high quality pencil media line reproduction agent for creating aesthetically pleasing lines that mimic human-drawn lines. The method avoids computationally expensive techniques and large storage space. The system is not intended to replace artists or illustration, but to provide a tool for users with no training to produce traditional images using a penc...
متن کاملPencil it in: pencil drawn electrochemical sensing platforms.
Inspired by recent reports concerning the utilisation of hand drawn pencil macroelectrodes (PDEs), we report the fabrication, characterisation (physicochemical and electrochemical) and implementation (electrochemical sensing) of various PDEs drawn upon a flexible polyester substrate. Electrochemical characterisation reveals that there are no quantifiable electrochemical responses upon utilising...
متن کاملCathodic Electrochemiluminescence of Lucigenin at Disposable Oxide-coated Aluminum Electrodes
Electrogenerated chemiluminescence (ECL) of lucigenin is induced at oxide-coated aluminum electrode in aqueous solution by cathodic pulse polarization. This ECL can be enhanced by the presence of coreactants such as peroxodisulfalte. The present method is based on the injection of hot electrons into the aqueous electrolyte solution, which probably results in the generation of hydrated electrons...
