ASSOCE

This technology has been patent-filled on march 2022 under the number PCT/FR2022/050396 and is co-owned by University of Caen Normandy, National Graduate School of Engineering of Caen (ENSICaen) and  National Center for Scientific Research (CNRS).

Description:

This technology consists of an electric field generation device and an electric field detection device.
The electric field generation device, or omnidirectional source, is designed as a truncated cone supporting a sphere at its apex. The cone includes an internal conductor that channels electric charges to the center of the sphere, an external potential difference generator, and an external organic conductor that enables the return of electric charges to the generator.

The internal conductor, running from the cone to the center of the sphere, enables the generation of a uniform electric field around the sphere. The device is designed such that the electric field produced by the sphere replicates the field that would be generated by an ideal isolated conductive sphere carrying the same instantaneous electric charge.

The detection device is a three-axis sensor shaped like a cube, with each face consisting of three pairs of electrodes. Since the electric field source operates at low frequency, the sensors are not affected by interference from the field-generating equipment.
