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).
