We are pleased to announce that our joint work with Technische Universitรคt Darmstadtยดs Integrated Electronic Systems Lab has been accepted for presentation at the ๐๐ฒ๐ป๐๐ฟ๐ฎ๐น ๐ฎ๐ป๐ฑ ๐๐ฎ๐๐๐ฒ๐ฟ๐ป ๐๐๐ฟ๐ผ๐ฝ๐ฒ๐ฎ๐ป ๐จ๐น๐๐ฟ๐ฎ๐๐ผ๐ป๐ถ๐ฐ๐ ๐ฆ๐๐บ๐ฝ๐ผ๐๐ถ๐๐บ (๐๐๐๐จ๐ฆ).
In this research, we integrated our ultrasonic through-metal backscatter communication system into a standard M20 bolt, enabling the wireless readout of sensor data from within the metal structure.

Our approach opens up new possibilities for retrofitting existing machinery with smart, ultra-low-power sensors embedded directly into standardized components. Such sensor-integrating machine elements could enable continuous condition monitoring with minimal installation effort and without the need for radio-frequency based wireless communication, which is often severely limited in metallic environments.
