TWA 36

Printed, flexible and stretchable electronics

Printed, flexible and stretchable electronics are a class of advanced materials that enable important new paradigms for electronic devices and products. They include conductive inks, polymers, and organic semiconductors. Applications span energy technologies, displays, lighting, sensors, and wearable electronics. However the development and adoption of new materials into electronic devices requires robust measurement methods and internationally-agreed standards.

The TWA reviewed standardisation requirements for printed electronics and contributed to meeting those needs. A key output from this TWA was the evaluation of a proposed benchmarking method for charge carrier mobility in organic semiconductors, leading to publication of IEC 62899-202-11:2025. A second output was evaluation of a method for lateral resolution measurements for confocal Raman spectroscopy, which contributed to the published standard ISO 23124:2024.

In 2024 the VAMAS steering committee recognised a shift in the global focus towards the broader category of semiconductor materials and therefore responded by closing TWA36 in favour of the new TWA 46 “Semiconductors”.
