Printed sensors to collect battery level data and expand the range of electric vehicles.
- Printed sensors for battery and car seat monitoring RECARO
- Innovative applications improve the safety, comfort and range of electric vehicles
- Sensors are drivers of digitalization throughout the industry
- High market potential for the future
Heidelberger Druckmaschinen AG (Heidelberg) presents innovative applications for the automotive industry at LOPEC, the leading international exhibition of flexible, organic and printed electronics. Together with Heidelberg’s InnovationLab the company will introduce in late March printed sensors for battery monitoring and RECARO car seats. Heidelberg has already set up its own business unit for the industrial development, production and sale of printed electronics for this growing market, and has set up production at the Vistula-Waldorf site. In the future, it will produce electronic components and sensors for digital applications, especially in healthcare and logistics, as well as in retail or the automotive industry using the latest printing technologies.
“The printing electronics market, especially sensors, is Heidelberg’s future,” said Rainer Hundsdorfer, CEO of Heidelberg. “With the solutions presented to the automotive industry, we have good opportunities to further expand our business in this segment. We see opportunities for growth for us as an operator in the production of high-tech sensors in the range of two to three million euros.”
Using a car seat developed by RECARO Automotive GmbH, visitors can see how the pressure sensor foil can detect passengers and distinguish them from other objects. The information obtained can be used for driver assistance and safety systems, such as seat belt reminders and deactivation of the airbag when a child seat is detected. The presented matrix of sensors also allows to define, what position of a seat is occupied by passengers. This will be especially important with (partially) autonomous control for the operation of safety systems, as the driver’s position will be much more variable.
An innovative solution for battery control will also be presented. Printed ultra-thin pressure and temperature sensors can capture spatially separated data from individual battery cells, which can extend battery life by up to 40%. The printed sensor films are thin enough to fit between individual battery cells and capture detailed pressure and temperature data. This cell-level information provides valuable information about battery status and performance, helping research teams and developers improve battery design – including to expand the range of electric vehicles.
“With the industrial production of functional films equipped with sensors, Heidelberg opens a new playing field for digital business models. Each square meter of film is equipped with up to a million sensors that detect the smallest changes in pressure, temperature or humidity. Data obtained in this way artificial intelligence and provide quality information that goes beyond discrete measured variables, ”said Dr. Michael Kreger, Managing Director of Heidelberg Printed Electronics GmbH. “In this process, all sensor technology is printed in one pass, including all current tracks, sensors and the interface to digital end devices.”
The LOPEC exhibition will be held in Munich from 22 to 24 March 2022. Heidelberg will be exhibiting its range of products and services together with InnovationLab at booth B0.510.
In addition, CEO Rainer Hundsdörfer will deliver a keynote address at the congress, which is being held at the same time: Rainer Hundsdörfer (lopec.com)
