SENSOR+TEST 2025

Magnetic fields, light, gases and odors have one thing in common: they contain information that cannot be perceived with the naked eye. Convince yourself of this and discover the intelligent sensor systems of the Smart Sensing and Electronics division of Fraunhofer IIS at the SENSOR+TEST from May 6-8, 2025 in Nuremberg. We will be presenting our HallinMotion^® algorithm for 6D position measurement and our nanoSPECTRAL technology, with which we enable a chip-size spectrometer in cost-effective CMOS technology.

Our highlights at the trade fair

HallinMotion^® – Multidimensional position measurement

Intelligent Hall sensors provide the position and orientation of encoder magnets of any shape as a digital output signal and are therefore universally suitable for a wide range of applications in position and current sensor technology. Our HallinMotion^® algorithm guarantees that the absolute position can be determined precisely in all installation situations, as it records the movements with all six mechanical degrees of freedom with just one measuring system. This measuring system, which consists of just one magnet and one sensor chip, enables measurement rates in real time within a few milliseconds and is also robust against interference fields and temperature influences. The HallinMotion^® algorithm is therefore particularly suitable for high-precision applications in the field of industrial automation, but also in automotive engineering or white goods.

HallinPower^® - Flexible galvanically decoupled current sensors

Current-carrying conductors generate magnetic fields that can be measured without contact. Traditional approaches often use magnetizable cores or flux concentrators to concentrate the magnetic field. However, this technology comes with challenges such as saturation, hysteresis and other non-linear effects. HallinPower^® technology breaks new ground: it completely dispenses with magnetizable materials and thus enables interference-free, precise measurement of the flowing current. Precise measurements in cars, industrial plants and smart homes are becoming increasingly important, especially in the context of the energy transition. HallinPower^® offers flexible solutions that are easy to install, require no calibration and can measure multiple currents simultaneously.

nanoSPECTRAL – Optical filters in CMOS for low-cost chip-size spectrometers

Due to the high cost of multispectral sensors with more than six spectral channels, they are not used in many price-sensitive markets. Our nanoSPECTRAL technology is based on optical nanostructures and enables very cost-effective monolithic production of the required optical filters directly in CMOS semiconductor processes, together with the optical sensor elements. The chip-size spectrometer shown at the trade fair already has 320 channels in the visible (VIS) and near-infrared (NIR) wavelength range and is therefore suitable for agricultural applications, analytics, food analysis and medical applications, for example.
