CDA Datentraeger Albrechts GmbH is a recognized specialist for the manufacture of complex microstructures, for example, as used on plastic optical elements. CDA has now extended its offering through the combination of microstructured optical components and printed electronics.
The field of organic and printed electronics falls directly within one of the EU’s designated key enabling technologies (specifically, Microand Nanoelectronics). Often termed disruptive for the innovative opportunities provided, these devices are forecast to play a vital role in sectors as diverse as automotive and transportation, aeronautics and space, with applications in the development of consumer electronics, lighting, display and security fields, so too in so-called smart systems. In particular their combination with optical devices and as an enhancement for optical applications is of particular interest.
CDA recently developed an innovative process for printing electrical conductor tracks. This technology has now undergone further development such that tracks, switches as well as capacitive and inductive electronic components can be cost-effectively integrated onto a plastic substrate through a combination of multi-layering and structuring steps. The process is capable of high volume, with feature sizes commonly around 100µm - features down to 40µm are also reliably available. Common materials are carbon, silver and gold, with others available upon request.
Importantly, CDA is the first company to offer printed electronics in combination with functional microstructures. Printed electronics can now be creatively combined with functional surfaces and structures on plastic to enable new, innovative applications and solutions - for example for microfluidic Life Science applications. CDA’s technology also provides a route for combining electronic and optical functionality in the same device. The next goal for CDA’s development is the capability to include printed batteries, thus providing an energy source for both optical and non-optical applications.
