Elwave

Founded in 2018, Elwave is a limited company headquartered in Carquefou, France with approximately 11-50 employees specializing in Other.

Elwave is an innovative French start-up that develops bio-inspired electric field sensors for subsea detection, navigation, and characterization. The company transforms the electrical sensory perception mechanism used by tropical fish (electric sense) into advanced technological solutions for underwater robotics and marine applications. Elwave's core technology, CEDAR (Controlled Electric Detection And Ranging), enables detection and classification of objects on the seabed and in the water column, complementing acoustic, magnetic, and optical sensing methods. The company offers a complete suite of products including EPULSE (active electric field sensors) and ESENSE (passive electric field sensors), which are integrated into ROVs, AUVs, USVs, and other subsea vehicles. Applications span defense and security (mine countermeasures, anti-submarine warfare, critical infrastructure surveillance), marine sciences (archaeology, environmental surveys), and commercial sectors (cable and pipeline inspection, seabed characterization). All systems are designed and built in-house, with capabilities to develop customized solutions for specific operational requirements.
