Pencil 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 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 کاملAutomatically Mimicking Unique Hand-Drawn Pencil Lines
In applications such as architecture, early design sketches containing accurate line drawings often mislead the target audience [Schumann et al., 1996]. Approximate human-drawn sketches are typically accepted as a better way of demonstrating fundamental design concepts. To this end we have designed an algorithm that creates lines that perceptually resemble human-drawn lines. Our algorithm works...
متن کاملPencil 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...
