Our highly integrated and wireless individual solutions turn your components and machines into smart products: They obtain data directly from the component and thus enable digital business models such as predictive maintenance - without requiring complex adjustments to the component design.
We find the right sensor technology for you and couple it with our ultra-high efficiency technology.
Whether you want to monitor forces, loads, vibrations, temperatures or other measured variables, we will find the right sensors for you. Together with our highly efficient radio technology, we develop smart sensors that are adapted to your application and enable you a completely wireless machine monitoring.

nemi DAQ nano is a tiny wireless multi sensor with energy harvesting module for measuring and monitoring strains, forces, displacements and much more. It is designed to meet the needs of many demanding use cases without the cost of custom development.
nemi G+ nano is a tiny, wireless sensor with Energy Harvesting module for measuring and monitoring accelerations, vibrations and rotation rates. Because of the compact and lightweight design nemi G+ nano can easily be integrated in smallest installation spaces and turns your components and machines into smart products.
Use Case
Wireless integration of radio sensors in a grinding spindle of a machine tool to measure vibrations and forces occurring during the grinding process: The sensory spindle thus enables an autonomous, self-monitoring and self-regulating grinding process.
Challenges
Smallest installation space
Battery charging without retooling
Wireless data transmission from the inside of the machine
Electromagnetic interference
Solution & Advantages
Structure-integrated Condition Monitoring
Monitoring sensitive properties by integrated sensors
Reliable data despite seal and housing
Autonomous, fast battery charging
In the space of a 1-euro coin, we accommodate completely wireless sensor modules. In addition to signals from for example strain gauges, temperature and pressure sensors, the modules also record acceleration and rotation rates in and around all three spatial directions or axes. All data can be provided live via radio data transmission.
To make your machine element even smarter, data pre-evaluation / data reduction can be performed via edge computing on the sensor module.
High-performance radio technology: High live sum sampling rate per radio channel of up to 36 kHz at 24 bits/sample. Up to eight radio modules per radio channel can be coupled to one receiver. Our fully synchronized radio networks operate with time deviations below 20 microseconds and low latencies.
Years of battery life: Minimal power consumption in operation and sleep mode due to i4M's ultra-high efficiency technology
Integrated computing power for online algorithms and edge computing
Highly integrated and compact design: adjustments to the component design can be avoided
Completely wireless: Powered by battery, rechargeable battery or energy harvesting and with integrated radio data transmission
Energy Harvesting possible depending on location (e.g. by means of Peltier elements or solar cells)
Robust and extensively tested: Under oil, in large gearboxes, under strong electromagnetic interference fields, on various machine elements, streetcars and wind turbines.
Various sensors can be connected:
Use Case
To record the rotational movement of rolling elements in large bearings, we have developed a measuring system consisting of sensors integrated in the rolling element, whose collected data are transmitted wirelessly to a receiver. In this way, a rolling element became a smart machine element.
Challenges
Small installation space
Contactless battery charging
Optimal radio performance despite metal & lubricant
Solution & Advantages
Fully integrated molded measuring system
Highly efficient wireless measurement technology
Reliable data transmission
Edge computing in the rolling element
We develop customized solutions for your application on the basis of extensive experience from various industries and our completely self-developed hardware and firmware. In the shortest possible time, we thus arrive at the first prototypes with which data can already be obtained.
Upon request, we can take over the data analysis. To reach your goal we use the most modern algorithms according to the current state of science and technology. We subsequently apply these algorithms directly in the sensor modules, thus enabling the reduction of Big Data to Smart Data by edge analytics. This saves energy during data transmission, increases battery runtimes and reduces complexity in the subsequent data handling steps (storage, analysis, presentation).
Use Case
In a project with Fraunhofer ILT, we have developed highly integrated, wireless measurement technology with a direct connection of a 3D printed strain gauge that can be used for the smart recording of mechanical and thermal loads on components. This technology can be used in a wide range of applications and makes machine elements smart.
Challenges
Compact installation space
Long battery life
Direct connection of the 3D printed strain gauges
Solution & Advantages
Wide range of use even in the smallest applications
Highly efficient wireless measurement technology
Edge computing capability
