Flexibility Meets Precision

Germany - Kleinostheim, 22.06.2022

Heraeus Nexensos and accensors Launch Strategic Cooperation to Integrate Miniaturized Temperature Sensors into Film Sensors.

Miniaturization is playing an increasingly important role in the fields of medical applications, diagnostics and wearables as well as in the automotive and industrial environments. With a direct recording of inflammatory parameters on the patient, irregular conditions can be detected very early in the post-operative care, for example. Film sensors open up a very wide range of applications by recording parameters such as pH value, conductivity, humidity, pressure and temperature. Precise temperature measurement is of central importance both as a measurand and as a reference value for other sensors.

As part of a strategic cooperation, temperature sensor expert Heraeus Nexensos and film sensor expert accensors will jointly develop solutions to support the trend of miniaturization and integrate precise temperature sensor elements into highly integrable film sensor elements and application-specific film sensors. In particular, miniaturized temperature sensors of the microRTD series are used, which enable new applications with a footprint of only 0.6 × 0.3 mm and a height of less than 40 μm. The low height of the innovative temperature sensors thus allows direct integration into film sensors in order to achieve precise and direct detection of the temperature.  In combination with ultra-thin films with material thicknesses of 12 μm, extremely flat film sensor systems with a total profile of less than 100 μm can be realized.

The two partners are combining their expertise to increase the measurement accuracy of the film sensors and expand the application areas of film sensor technology by integrating the newly developed temperature sensors. In conjunction with other platforms, multiparametric film sensor systems are implemented in order to ensure the most meaningful state detection possible in an application-adapted manner.

”By combining different sensor technologies, we achieve a classic win-win situation: We see this point when using our microRTD temperature sensors in film sensor systems. Thanks to our miniaturized, ultra-thin and bendable elements, the film sensor systems remain flexible and can be integrated into a variety of applications," says Christoph Hartnig, VP Business Development at Heraeus Nexensos, explaining the importance of the strategic cooperation.

"We see the use of microRTD temperature sensors as a complementary technology to our film sensors manufactured in printing technology. It is a synergy of our technological possibilities with the clear goal of providing our customers with even more measurement accuracy and higher precision," adds Eike Wilhelm Kottkamp, CEO innoME/accensors.

Due to the geometric design freedom and flexibility of accensors film sensors, combined with the high-precision temperature sensor elements from Heraeus Nexensos, printed electronics and innovative SMD technology merge. The cooperation partners see this technology combination as forward-looking and are working on further fields of application in which miniaturized and flexible sensor platforms are the central component.
