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.
Understanding e-Nose Chemical Sensors
Electronic noses are ingenious devices that detect odors or flavors. Over the past few decades, they’ve become invaluable tools for chemical detection. The heart of these sensors lies in their ability to detect volatile organic compounds with sensitivity and specificity, a task where the design of the sensor’s electrodes is critical.
The Role of Gold Electrodes
Gold’s exceptional electrical conductivity and resistance to corrosion make it the gold standard for electrode materials. In the realm of e-Nose sensors, gold electrodes are unparalleled in their efficiency, offering consistent and reliable readings that are critical in the precise detection of chemicals.
Take a look at the image showcased here—it’s a prime example of the intricate gold electrodes we fabricate at Platypus Technologies.
The process for manufacturing these electrodes is meticulous:
- Gold Deposition: We start by depositing a thin layer of gold onto a substrate via e-beam evaporation, ensuring uniformity and precise thickness for optimal sensor performance.
- Photolithography: Next, we employ sophisticated photolithography techniques to etch the gold into patterns that will form the active sensing area of the e-Nose.
- Dicing: With precision dicing, we segment the substrate into individual sensors, each a marvel of miniaturization and accuracy.
- Electrical Characterization: Finally, the electrodes are rigorously tested to guarantee electrical integrity and performance, ensuring that our clients receive only the best.
