About

Elwave is a defense subsystem manufacturer based in Carquefou, France working in naval systems, radar & sensors.

Elwave is a French start-up developing bio-inspired electric field sensors for subsea applications. Its sensing technology, derived from electric sense in tropical fish and developed since 2007 by the LS2N biorobotics research group, detects and classifies objects on the seabed and in the water column. Its product lines include the EPULSE active and ESENSE passive electric field sensors, and the Tetrapulse and Octopulse sensors for ROVs and AUVs. Applications include mine countermeasures, detection of unexploded ordnance, anti-submarine warfare, subsea infrastructure protection, and underwater surveillance, alongside commercial uses such as marine science, archaeology and cable and pipeline inspection. The company describes itself as dual-use, targeting defense and commercial markets. Its sensors have been qualified at sea through the NATO DIANA programme. Elwave designs and builds its systems in-house, covering electric sensing, electronics, signal processing, mechanics and software, and offers standard products as well as mission-specific solutions.

Products

EPULSE

Active electric field sensor

Active subsea electric field sensor that emits an electric field and measures its modulation to produce electrical impedance images for detecting and classifying objects on the seabed.

ESENSE

Passive electric field sensor

Ultra-sensitive wideband underwater electrometer for detecting and classifying electric field sources at mid and long range, including USVs and AUVs.

Tetrapulse

Subsea electric sensor

Electric impedance sensor mounted on mini-ROVs for detecting and super-classifying buried or laid objects, including non-ferrous UXO.

Octopulse

Subsea electric sensor

Electric impedance sensor mounted on ROTVs or ROVs for large-scale, high-speed seabed surveys and mine super-classification.
