Abstract: The present invention relates to a field of procedures for the acquisition, treatment and transmission data linked to human energy consumption. A first activation phase (1a) of a device containing at least one acceleration sensor element and at least one temperature element and a microcontroller element is followed at least by a phase (3) to check for an active connection with a connected remote device, followed by a calibration phase (5), followed by a phase (6) to detect motion, followed by a phase (6b) to detect movement of the user's foot, followed by a phase (9) to detect the type of movement and a phase (11) to calculate and memorize the velocity, the movement and the energy.
