Biomimicry electrical sensors
ELWAVE offers a complete suite of subsea electric field sensors.
epulse Active electric
Emission of an electric field and measure of the electric field modulation by the environment. Provides an electrical impedance image of the seabed and the subseabed.
esense passive electric
Measure surrounding electric fields. Provides the detection and the classification of electric sources (time and spectral analysis).

epulse
EPULSE product range offers the world’s first compact active electric field sensors based on the ‘active electrolocation’ patented. Technology CEDAR® (Controlled Electric Detection And Ranging) for:
- Underwater detection, classification, localisation (DCL)
- Real-time electric impedance seabed imaging
- Centimetric spatial resolution: “Super-Classification”
- Detection of any metallic and non-metallic objects, including amagnetic material such as aluminium
- Detection of laid and buried objects
- Efficient in turbid and clear water, salt and fresh water
