Printed electronics are a true all-rounder. It adapts to uneven surfaces, handles any bend, can be applied to a wide variety of substrates, and is also cost-effective to manufacture. Many high-tech applications would not be feasible without it. From February 25 to 26, INM – Leibniz Institute for New Materials will present conductive inks with tailored properties and highly flexible electrofluids at LOPEC in Munich.
Depending on the application, printed electronic structures must meet different requirements – for example in terms of conductivity, flexibility, or stretchability. Depending on which function is the priority, the inks used must exhibit specific properties. Researchers at INM have therefore developed specialty inks with distinct functionalities. Depending on requirements, they are particularly stretchable or temperature-sensitive.
One INM ink variant was developed for energy-efficient, self-regulating heating systems. Thanks to its carbon-based composition, it is ideally suited for heated wearables, battery heaters, smart building applications, and uses in the automotive industry. A second variant is temperature-sensitive due to hybrid conductive fillers and stretchable materials. It is perfectly suited for industrial sensors, offering stable performance in temperature detection and monitoring under various environmental conditions. At the INM booth, the company flextem will demonstrate the use of INM inks in its temperature sensors. Another ink stands out for its excellent conductivity and high reliability under mechanical stress. It is screen-printable and ideal for applications requiring flexible or stretchable conductive materials. The elastic ink has already been tested and successfully validated in industrial practice.
As an innovative material for printing soft electronic components, INM will also present so-called electrofluids. These are exceptionally soft, liquid materials in which tiny conductive particles form a fine, dynamic network within a non-conductive base substance, enabling the flow of electricity. When stretched or moved, this network continuously reorganizes itself, ensuring that the material remains functional even when bent, pressed, or elongated.
LOPEC is the world’s leading trade fair for printed electronics. It takes place annually in Munich and brings together industry experts from science and industry. INM will showcase its functional inks and electrofluids at booth B0.610. In addition, the Saarbrücken-based materials research institute will present electrospun flexible transparent electrodes for touch applications at the booth of its cooperation partner Hamamatsu Electronics (booth B0.605).

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
