Fraunhofer Institute for Physical Measurement Techniques IPM

Measuring | Monitoring | Optimizing

The Fraunhofer Institute for Physical Measurement Techniques IPM develops tailor-made measuring techniques and systems for industry. Many years of experience with optical technologies form the basis for high-tech solutions in the fields of production control, object and shape detection, gas and process technology as well as thermal energy converters.


Business Unit

Production Control

We analyze surfaces and 3D structures of components quickly and with micrometer precision. This means that 100 percent production control in real-time is possible.


Business Unit

Object and
Shape Detection

We detect the three-dimensional shape and position of objects and large structures at high speed and with high precision. Measurements are taken predominantly from moving platforms.


Business Unit

Gas and Process

We develop and manufacture measurement systems for gas and liquid analysis which feature high precision and reliability even under extreme conditions. The scope ranges from laser spectrometers for exhaust gas analysis to energy-efficient gas sensor for  food quality monitoring.


Business Unit

Thermal Energy

We manufacture and optimize materials with special physical properties. These materials form the basis for systems for magnetic cooling or thermoelectric energy harvesting.


Fiber-based sensor for demand-based cleaning of closed food processing systems

In the food processing industry, closed production systems are cleaned according to strictly defined specifications – and often applying unnecessarily large quantities of chemicals. A fiber-optical fluorescence sensor developed at Fraunhofer IPM measures deposits in closed containers in a minimally invasive manner, thus enabling cleaning processes to be controlled and adapted to the actual degree of fouling.

Component traceability facilitates cross-process quality control

Industrial production processes can only be optimized if components can be tracked and traced from production to the point of integration into an assembly. Through the “ProIQ” project, Fraunhofer IPM has joined forces with partners from the fields of industry and research to develop technologies for adaptive production of precision components. To this end, the Track & Trace Fingerprint method has been extended with a view to tracking and tracing rotationally symmetrical objects.

Producing electrodes for Li-ion batteries more efficiently

Defects often occur in the production of electrode foils for lithium-ion batteries due to nonhomogeneous coatings. Fraunhofer IPM and Fraunhofer ISIT, together with partners from the fields of industry and research, have developed an optical inline measurement system that determines the material composition of electrode foils quantitatively and with depth resolution – directly in the production line. The goal here is to manufacture electrodes for Li-ion batteries more cost-effectively and with a higher level of quality.

Sensor technology for safe hydrogen handling

Measurement technology is indispensible to the use of hydrogen as an energy source. Sensors that reliably detect leaks in storage tanks, pipelines and supply points are needed to ensure that hydrogen infrastructure is operated safely. Fraunhofer IPM has been working with partners from science and industry for exactly one year on the TransHyDE joint project funded by the German Federal Ministry of Education and Research, which aims to develop new sensor designs that can ensure the safety of hydrogen technology, enable hydrogen purity measurements and determine H2 content in natural gas grids.
