Heidelberger is presenting innovative applications for the automotive industry at LOPEC, the leading international trade show for flexible, organic, and printed electronics. LOPEC takes place in Munich from 22 to 24 March 2022 and Heidelberg will be exhibiting its range of products and services together with its InnovationLab at stand B0.510. In addition, CEO Rainer Hundsdörfer will give a keynote speech at the Congress taking place at the show.

Together with its InnovationLab, the Heidelberg will present printed sensors for battery monitoring and RECARO car seats. The company has set up its business unit for the industrial development, manufacture, and sale of printed electronics for this growth market and established production at Wiesloch-Walldorf. In the future, electronic components and sensors for digital applications, particularly from the healthcare and logistics sectors, retail, or the automotive industry, will be produced there using state-of-the-art printing technology.

“The market for printed electronics, especially for sensors, is a future field for Heidelberg,” said Heidelberg CEO Rainer Hundsdörfer. “With the solutions presented for the automotive industry, we have good opportunities to further expand our business in this segment. We see growth opportunities for us as an operator in the production of high-tech sensors in the two to three-digit million Euro range.”

Using a car seat developed with RECARO Automotive, visitors can see how pressure sensor foils can detect occupants and distinguish them from other objects. The information obtained can be used for driver assistance and safety systems, such as reminders to fasten seat belts and deactivation of the airbag when a child seat is detected. The sensor matrix presented also makes it possible to determine which seat position passengers are occupying. This will be particularly important in (partially) autonomous driving for triggering safety systems, as the driver’s position will become much more variable.

An innovative battery monitoring solution will also be presented at LOPEC. Printed, ultra-thin pressure and temperature sensors can capture spatially resolved data from individual battery cells to extend battery life by up to 40%. Printed sensor films are thin enough to fit between individual battery cells and capture detailed pressure and temperature data. The cell-level information provides valuable insights into battery health and performance, helping research and development teams improve their battery designs. These could help in extending the driving range of electric vehicles.

“With the industrial production of sensor-equipped functional films, Heidelberg is opening up a new playing field for digital business models. Each square meter of the film is equipped with up to one million sensors that register the smallest changes in pressure, temperature, or humidity. The data obtained in this way is then processed using AI algorithms and delivers information quality that goes beyond discrete measured variables,” said Dr. Michael Kröger, managing director of Heidelberg Printed Electronics. “In the process, the entire sensor technology is printed in a single pass – including all conductive tracks, sensors, and the interface to digital end devices.”

The Covid-19 pandemic led to the country-wide lockdown on 25 March 2020. It will be two years tomorrow as I write this. What have we learned in this time? Maybe the meaning of resilience since small companies like us have had to rely on our resources and the forbearance of our employees as we have struggled to produce our trade platforms.

The print and packaging industries have been fortunate, although the commercial printing industry is still to recover. We have learned more about the digital transformation that affects commercial printing and packaging. Ultimately digital will help print grow in a country where we are still far behind in our paper and print consumption and where digital is a leapfrog technology that will only increase the demand for print in the foreseeable future.

Web analytics show that we now have readership in North America and Europe amongst the 90 countries where our five platforms reach. Our traffic which more than doubled in 2020, has at times gone up by another 50% in 2021. And advertising which had fallen to pieces in 2020 and 2021, has started its return since January 2022.

As the economy approaches real growth with unevenness and shortages a given, we are looking forward to the PrintPack India exhibition in Greater Noida. We are again appointed to produce the Show Daily on all five days of the show from 26 to 30 May 2022.

It is the right time to support our high-impact reporting and authoritative and technical information with some of the best correspondents in the industry. Readers can power Indian Printer and Publisher’s balanced industry journalism and help sustain us by subscribing.
