Project for intelligent sensor systems for Industry 4.0.

Multi-sensor systems form a crucial basis for the success of Industry 4.0 applications. They record, process, and transmit a number of measurement parameters, such as pressure, acceleration, and temperature, all in a highly compact space. Machines are not the only ones to receive such sensors; workpieces are also increasingly being fitted with the intelligent sensor systems so that each product can provide its blueprint and report its manufacturing status. Based on this information, production is largely able to organize and monitor itself.

Eleven research partners now aim to simplify and accelerate the development of intelligent multi-sensor systems. As part of the RoMulus project, they want to standardize and refine the steps leading up to the finished product in such a way that it is possible to produce even small quantities in a cost-effective manner. As a result, they are improving the market position of small- and medium-sized enterprises (SME) in the sensor technology sector.

In the future, SMEs will be able to offer their industrial customers customized sensor systems with considerably less effort and expense. The German Federal Ministry of Education and Research (BMBF) is supporting the RoMulus project as part of the IKT 2020 incentive program to the tune of approximately 4.5 million euros, which covers some 70 percent of the total investment amount.

Challenging development
The development of multi-sensor systems for Industry 4.0 applications is challenging. The task is to combine two technologies in a highly compact space, namely microelectromechanical sensors (MEMS), which measure mechanical parameters, such as pressure and acceleration, and microelectronic sensor components, which determine temperature, light intensity, and chemical concentrations. The finished systems must process large amounts of data in the most energy-efficient manner possible. Furthermore, they need to be robust enough to function reliably in an industrial setting.

Collaboration with semiconductor manufacturers and service providers
The German sensor technology sector predominantly comprises small and medium-sized enterprises. As a general rule, they are unable to cover all of the services themselves that are necessary for the development and production of multi-sensor systems, which is why they rely on close collaboration with semiconductor manufacturers and service providers for research and development. “We want to disentangle and standardize this collaboration − and thereby the design and manufacturing processes,” says project coordinator Dr. Eckhard Hennig, professor at Reutlingen University. In the future, SMEs will be able to select and compile development services as well as electronic components as if from a large kit, depending on what solution the customer requires for their very specific industrial application.

“RoMulus makes it possible to systematically design and cost-effectively manufacture robust, energy-efficient multi-sensor systems, even in small quantities. As a result, German sensor technology manufacturers are leading the field in terms of creating an important technological basis for Industry 4.0 applications,” explains Dr. Reinhard Neul from Robert Bosch GmbH.

• Eleven partners from research and industry
The abbreviation RoMulus stands for “robust multi-sensor technology for status monitoring in Industry 4.0 applications.” The project began in October 2015 and is scheduled to last three years.
As part of the RoMulus project, eleven partners are pooling their expertise – from semiconductor manufacturers and development companies to SMEs. They are as follows: Zeiss, the Fraunhofer Institute IIS/EAS, Reutlingen University, Institut für Mikroelektronik- und Mechatronik-Systeme gemeinnützige GmbH, microsensys GmbH, Robert Bosch GmbH, the Technical University of Munich, TETRA Gesellschaft für Sensorik, Robotik und Automation mbH, the University of Bremen, the University of Freiburg, and X-FAB Semiconductor Foundries AG. The edacentrum in Hanover is responsible for project management.
