With the emerging demand for flexible electronic devices, there is currently intensive research on organic conductive materials. Ionic liquid-polymer gels can combine high ionic conductivity and good transparency with mechanical flexibility. A new solventfree process for the fabrication of inkjet printed ionic liquid-polymer gel microstructures with high resolution is presented by Ute Löffelmann, Nan Wang, Dario Mager, Patrick J. Smith, and Jan G. Korvink on page 38 of this issue. Gel properties can be controlled by choosing different types and amounts of ionic liquids and monomers. The microscope image on the cover and left shows a structure created on the gel surface when it is detached from a glass slide.
