Conductive Ink Technology
#Shorts
Conductive ink is a fantastic material that actually lets you draw working circuits on various materials like paper or textiles. There has been a lot of hype in recent years about how it will eventually replace traditional circuits.
But is this true?
Here we'll explore what conductive ink is, how its made, its pros and cons, and see in which industries it is currently being used.
What is conductive ink?
Conductive ink, as the name suggests, is a form of ink that can conduct electricity. In most cases, the ink is infused with a conductive material, like graphite or silver, to enable electrical conduction.
For some, it is a technological panacea that may, one day, enable electrical circuits to be printed on paper or other flexible surfaces. It could even be used using inkjet technology.
As well as inks, some companies, like Bare Conductive in the UK, have produced paint products that can also conduct electricity. Working much like conductive inks, conductive-paint can be used as a cold solder, to repair PCBs and many more other applications.
But we are not there yet. They are, for example, not without their downsides (like when washing textiles for instance).
"There are already some simple circuit boards made using conductive inks. For example, some subway and train systems use them to print circuits onto disposable passes. But the downside to conductive ink circuits is their resistance. Solid, pure metal will always be more conductive than the flakes or powder in conductive ink, so solid copper circuits will be more efficient with electrical energy and generate less heat," according to scienceline.ucsb.edu.
