Electrical Characterization of Interdigitated Electrodes (IDEs)

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.

Improved sensors for water contaminants using Au(111)

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.

What is Shadow Masking? 

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.  

Emerging Technologies – Internet-of-Things

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.  

What is a Disk Electrode Used For?

Disk electrodes are one of the essential components for performing many electrochemical experiments.

Biological Testing with Patterned Electrodes

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.

Patterning Metal Surfaces Using Shadow Masks

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.

Using Patterned Electrodes for Chemical Sensors

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.

Chemical & Biosensor Chips Based on FETs

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.

Chemical & Biosensor Chips: CNTs, Graphene & More

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.
