Objective
- Demonstrator of a smart component using i4M's highly efficient telemetry and a direct connection of a 3D printed strain gauge
- Collection of component condition data such as mechanical and thermal loads using highly integrated smart measurement technology to realize intelligent machine elements
Partner
Fraunhofer ILT – Institute for Laser Technology
Period
since 2019
Challenges
- Small installation space
- Long battery life
- Direct connection of the 3D printed strain gauges
Realization
- Measuring system consisting of a transmitter module integrated in the component including battery and a receiver module for data acquisition
- Connection of a strain gauge full bridge or a resistance thermometer to SMD pads directly on the transmitter module
- MEMS sensor technology integrated on the transmitter module for measuring accelerations and rotation rates
- Wireless data transmission with nemi Link 2400, i4M's radio technology in the 2.4 GHz frequency band, via integrated antenna to a receiver module nemi Connect
- Charging of the built-in battery via Micro USB cable
- Software for live data display for demonstration purposes at trade shows
Advantages
- Wide use of highly integrated measurement technology to measure component loads even in the smallest applications
- Highly efficient wireless measurement technology and long battery life due to robust radio technology nemi Link 2400
- Capability for edge computing on the transmitter module
