A sealed electronic module () including at least one actionable part (), the module () including a case () having: a watertight compartment () containing a printed circuit board (), the compartment () being formed by a housing () with a unique opening (), the housing () including the printed circuit board (), and a sealing element () configured for closing tightly the unique opening () by being fixed to the housing () and the printed circuit board ().

Sealed electronic module

A wearable device () including a case () including a watertight compartment () containing a printed circuit board (), the case () being assembled to a strap () for mounting this wearable device () on a body part of a user, said assembly of the case () with the strap () being configured so that a portion () of this strap () includes at least one actionable part of the device ().

Wearable device strap with watertight actionable part

The smart battery () includes an electronic module provided with an electronic circuit () for controlling the supply voltage, which is disposed in a case having a cover () as the external negative terminal, fixed to a cup (), as the external positive terminal. A first chemical substance () as the anode and a second chemical substance () as the cathode, are inside the case. The electronic module includes a printed circuit board () having a first face with conductive paths, connected to the electronic circuit, and a second insulating face fixed to the second chemical substance. The electronic circuit is connected at output to a first connection pad connected to the cup. The electronic circuit is connected to the chemical substances by a second connection pad on a first tab (') and by a third connection pad on a second tab (&#x2033;) folded at 180&#xb0; on the second face of the printed circuit board.
