From May 6 to 8, 2025, the CiS Research Institute will present its current portfolio at the world’s leading forum for sensor, measurement, and testing technology, Sensor+Test in Nuremberg. Interested visitors will find us in Hall 1 at our booth 501 in the Nuremberg Exhibition Center. Our experts will be there to present numerous new developments and project results and look forward to talking with you.
Initial information about our highlights in the field of silicon-based sensor technology for customer-specific developments and applications is available for download and review:
Micro-optical particle counter for large volume flows (NewPARZ)
The NewPARZ Demonstrator is an optoelectronic particle counter for gas-borne particles with very low particle concentrations at high volume throughputs > 50 l/min. A special photodiode array with an angle filter changes its transmission at the laser wavelength from nearly 100% to an optical density (OD) of less than six over a few degrees of angle. This allows multiple measuring points along the laser curtain to be queried separately and in parallel with the photodiode array.

Photodiodes without back reflections (PoRr)
For low-light or polarization-sensitive measurement setups, light reflections in the setup can distort the measurements. For such requirements, silicon photodiodes with a rugged surface structure have been developed, which act as light traps and thus suppress disturbing light reflections in the spectral range from UV to NIR.

Fast infrared emitters (FIRE)
Infrared MEMS emitters are miniaturized high-tech alternatives to traditional incandescent lamps and serve as light sources in NDIR sensors. They are stable over long periods of time, dynamic, and emit in the spectral range from 2 to 15 µm. As part of the FIRE project, the dynamics and usable optical power have now been increased again to over 100 Hz.

High-pressure sensor with front-flush media connection (DS300MPa)
For applications above 70 MPa, thin-film technology on steel is predominantly used. Sensors with front-flush media connections can only be implemented with this technology at great expense. A new technological development enables strict separation from the electrical side and allows for customer-specific adaptations.

Pressure sensor for ultra-high pressure applications (DSNemo)
Traditionally, pressure sensors use a bending plate to increase sensitivity. For ultra-high pressure applications, a bending plate is not necessary and the design is significantly reduced in size. The new technology platform offers many possibilities, including a front plate with a diameter of 1 mm, a pressure range up to approx. 20,000 bar, a measuring range of > 20 mV/V, and a maximum operating temperature of 200 °C.

Sensors for monitoring belt tension (ZugKraftSensor)
A Si-DMS-based sensor has been developed for transmission belts to plan maintenance intervals and detect material fatigue at an early stage. The sensor system is integrated directly into the belt and is mechanically protected. Contact and signal output are wired. The system operates between -10°C and +80°C, with a maximum force capacity of 40 kN and a measuring range of 20 mV/V.
