ELWAVE IS THE WORLD’S FIRST AND ONLY COMPANY TO OFFER PRODUCTS AND SYSTEMS BASED ON INNOVATIVE “ELECTRIC SENSE” TECHNOLOGY.
Electric sense: biomimetics
ELWAVE develops solutions based on electrical sensory perception, known as “electric sense”, developed since 2007 by the biorobotics research group in Mines-Telecom Atlantique Institute.
ELWAVE technology takes its inspiration from the sensory mode used by tropical freshwater fish (African mormyrids and South American gymnotiforms), which have developed electrical sensory perception in order to move around, capture their prey and communicate with each other in an environment where vision and sonar (acoustic communication – echolocation) are ineffective.
Electrical sensory perception is based on sensing disturbances produced by the environment in an electric field generated by fish: these fish emit a 360° electric field around themselves which is disturbed by obstacles in their habitat, by other fish and by predators. The electro-receptor cells in their skin detect, measure and record these disturbances to create a three-dimensional image of their surroundings at any given moment.

Since 2007, the biorobotics research centre shared by ARMINES and Mines-Telecom Atlantique Institute has been developing command-and-control sensors and algorithms for underwater robots using this technology, in the framework of industrial contracts, the French National Research Agency and European projects (FP7 Angels, H2020 Subcultron).
Electric sense systems are based on the following principle:
Emission of an alternative current, low frequency electric field (+ pole)
Measurement of change in intensity (I) of currents in each electrode (- poles).
Algorithmic process for detecting and characterising objects, and for navigation functions.
Research has demonstrated the effectiveness of electric sense for many applications in diverse environments (seawater, freshwater, sediment, air), and particularly in assisted navigation for underwater robots, sediment analysis (detection of strata and buried objects), and obstacle avoidance by industrial robots (cobotics).
The advantages of electric sense
ELWAVE systems provide a unique combination of detection abilities. No other detection or surface characterisation technology (magnetometer, sonar, infrared, video, capacitive, etc.) currently exists which offers this ability.
