Printed electronics on a roll

Printed and organic electronics 'need new test methods'

Printed and organic electronics offer big opportunities for innovation but may be incompatible with current test and measurement techniques, an electrical test specialist has warned.

Keithley Instruments said that while these new technologies could change the world of electronics by enabling the manufacture of low-cost devices or solutions that are not possible with today’s inorganic electronics, that will depend on engineers and scientists fully understanding the electrical properties and operational characteristics of printed and organic materials and devices.

“To achieve this potential, making accurate measurements on fabricated devices and printable inks will be essential. Knowing how to reduce various sources of measurement errors will be critical to success,” the company added.

It said it plans to address this by broadcasting an online seminar, “Understanding Electrical Characterisation of Printed and Organic Electronics and Materials” on Thursday 27 January 2011 at 2pm GMT (15:00 CET).  Online registration for the free one-hour seminar is already open, the company noted.  

The seminar’s presenter Jonathan Tucker, a senior scientific research expert with Keithley, said that as well as covering methods and best measurement practices for electrically characterising printed and organic electronics and materials, he will discuss practical application examples where such measurement principles are required.

He added that participants will learn about techniques for measuring the conductivity of printable e-inks and I-V characteristics of organic electronics, and the sources of measurement error that will affect such measurements. They will also be able to ask questions interactively during the live broadcast, he said.
