Welcome to the fascinating world of electronic noses (e-Noses)—the cutting-edge nano-technology used to detect the presence of various compounds. At Platypus Technologies, we pride ourselves on pushing the boundaries of sensor technology, offering bespoke design and fabrication of sensors and electrodes. Our focus in this blog? The role of gold electrodes in e-Nose chemical sensors.
Interdigitated electrodes (IDEs) are widely used as pressure sensors and transducers in the medical electronics industry. IDEs have also found use as strain gauges and force sensors, as well as in chemical sensor applications. To characterize IDEs, electrical measurements of resistance, capacitance and impedance need to be implemented. This article discusses how to perform an electrical analysis of IDEs.
New research published in the Journal of the American Chemical Society, led by Professor Fernando Garzon of the University of New Mexico, demonstrates a novel strategy to improve sensors for water contaminants. The new approach involves using a thin films of highly oriented gold Au(111) on an electrode to enable redesign of the sensing surface and enhance its sensitivity.
In semiconductor fabrication, stencil metal plates or shadow masks can be used to designate where a metal is deposited upon a substrate. The stencil serves as a medium for achieving custom designs onto a substrate without the need for photolithography processes. This works by masking certain areas of a substrate while exposing others to be deposited with metal.
Internet of things (IoT) encompasses physical things that connect and exchange data with other technology. IoT offers increased connectivity, cloud computing, machine learning, and advancements to AI. Emerging advancements in IoT include machine monitoring, wearable health monitoring, inventory management, and public safety enhancements. IoT works through device-to-device communications that is conducted through sensor technology and actuators.
Electrodes are conductors that permit a flow of electricity in and out of an object. The application range for electrodes is vast, and various different types exist for distinct purposes. The surface resistivity electrode is one of these unique formats.
Disk electrodes are one of the essential components for performing many electrochemical experiments. Measurements such as cyclic voltammetry are widely used methods for the characterization of nearly any material or process that involves electron transfer – something ubiquitous in any material or component that will be used as part of an electronic system.
Cutting-Edge Engineering Developments in the Biosensor Polymer Manufacturing Industry
Recently, a novel organic semiconducting material was engineered which has the potential to push next-generation biosensor development to new heights. This innovative new carbon-based semiconductor polymer was specifically developed to surpass current biosensor options in sensing performance, reliability, as well as overall biocompatibility.
Biosensors are the core component of many cutting-edge technological initiatives – from state-of-the-art healthcare devices to the agricultural and industrial manufacturing sectors.
Interdigitated electrodes (IDEs) are fabricated through the process of combining two separately addressable electrode arrays, such that the resulting electrode structure is in a zipper-like or comb-shaped arrangement.
Characterizing and testing biological samples can be done through patterned electrodes. The overall structure and quality of an electrode can either enhance or impinge on sampling results. An ideal electrode design should attain a high signal-to-noise ratio (SNR), a low electrode impedance, and display resistance to harsh biological environments. Current generation and transportation depend on the metal coating present on an electrode surface.
Microelectrodes are specially patterned electrodes with very small tip diameters (less than 1 µm) that enable in-vitro electrochemical measurements in living tissues. Other applications using microelectrodes include measuring substance concentrations and determining pH levels.
Surface patterning describes fabrication methods which modify substrates with extreme precision.
The need for detailed surface structures is becoming increasingly common for scientists across a range of disciplines and there are many means with which these surface patterns can be created.
In this blog, we discuss surface patterning with shadow masks, an important tool for fabricating thin film components for microelectronics in a rapid and repeatable manner.
Small-scale patterned electrodes for scientific micro-electromechanical systems (MEMS) are intricate parts usually created by additive manufacturing (AM). At Platypus Technologies, we generate patterned gold thin films on glass created via e-beam metal evaporation using a titanium adhesion layer to enhance the mechanical stability of the film.
A field effect transistor (FET) is a key electronic component that is used throughout numerous areas of the electronics industry. FETs are largely used within integrated circuits, consuming much lower levels of power than integrated circuits using bipolar transistor technology meaning they can be used on a much larger scale.
A biosensor is an analytical device which is usually used to detect a chemical substance. They combine a biological component with a physicochemical conductor and are usually constructed of three segments; sensor, transducer and associated electrons.
Additive manufacturing (AM) is a growing engineering paradigm that enables technicians to produce a wide range of intricate, prototypical parts. Among these are small-scale patterned electrodes for scientific micro-electromechanical systems (MEMS).
