Concrete structures monitoring highlights: Our cable-free loggers are particularly effective for investigating crack severity and detecting bar corrosion in concrete structures such as bridges. The installation of independent loggers without the need for cables saves valuable resources and installation time. The loggers are equipped with high sensitivity MEMS 3D accelerometers and gyroscopes, enabling the establishment of correlations between strain and AE hits. This combination of acoustic emission sensing and 3D vibration mode analysis allows for the detection and classification of local flaws and defects in the entire structure.

Composite material testing and monitoring: Our novel surface wave sensors offer exceptional coupling to thin sheets, enabling accurate testing of composite materials, such as hydrogen pressure vessels, aircrafts, naval vessel. Coupled with AI-based flaw classification, performed in real-time on a PC or in the cloud, our system ensures efficient and reliable flaw detection.

In-flight monitoring: With our small-sized, battery-operated sensors, monitoring drones during flight or vehicles in operation becomes feasible. Our system records synchronized accelerometer and acoustic emission (AE) hits data, which can be easily downloaded from the logger to a PC via USB and uploaded to the cloud.

EV battery monitoring: The Acoustic Emission method is highly effective in detecting critical events in electric vehicle (EV) batteries. Our technology can identify hot spots in electrolyte leading to bubble formation, as well as changes in the cathode and anode crystalline structure. Early detection of such events helps prevent thermal runaway and facilitates optimal battery management.

Geological research of rock cracking: Our Ariel Logger has been successfully utilized for long-term investigations of rock cracking in the Dead Sea area. By employing battery-operated loggers, the Israeli Geological Institute efficiently monitored numerous rocks in the field study. This led to the discovery of a novel mechanism of cracking.

Large structures monitoring: Our technology enables the monitoring of large structures, such as pipes, bridges, ships, and roller coasters, utilizing up to 40 sensors over distances of up to 200 meters. This can be achieved with a single communication cable, and the data can be analyzed in real-time on premise or in the cloud. Real-time monitoring ensures timely detection and classification of flaws in these structures.

Biomedical applications: Our innovative technology enables the production of compact and efficient sensors for bone and joint diagnostics. Acoustic emission can detect micro-cracking in bones, friction in joints, and fiber tears in tendons and muscles, facilitating accurate diagnostics.

Emma Sensing welcomes partnerships to develop new applications tailored to our customers' specific needs and requirements. We invite you to collaborate with us in this endeavor and unlock the full potential of our technology.
