Thermoelectric watch testable in production or after-sales service

Abstract

A thermoelectric watch including a thermoelectric generator; a voltage booster connected to the thermoelectric generator; an energy management circuit connected to the voltage booster and configured to control the charging of at least one energy storage element, the energy management circuit including an output configured to change from a first logic state to a second logic state when the thermoelectric generator starts generating electrical energy, and to change from the second logic state to the first logic state when the thermoelectric generator finishes generating electrical energy.

1 . A thermoelectric watch comprising:
 a thermoelectric generator,   a voltage booster connected to said thermoelectric generator;   an energy management circuit connected to said voltage booster and configured to control the charging of at least one energy storage element, said energy management circuit including an output configured to change from a first logic state to a second logic state when said thermoelectric generator starts generating electrical energy, and to change from the second logic state to the first logic state when said thermoelectric generator finishes generating electrical energy,   wherein:
 a capacitor connected to said energy management circuit, configured to charge when said output of said energy management circuit changes from the first logic state to the second logic state or vice versa; 
 a conductive element electrically connected to the capacitor. 
   
     
     
         2 . The thermoelectric watch according to  claim 1 , wherein said conductive element is the back cover of the watch. 
     
     
         3 . The thermoelectric watch according to  claim 1 , wherein the management circuit includes a push-pull amplifier stage. 
     
     
         4 . The thermoelectric watch according to  claim 1 , wherein said energy management circuit is configured to alternately control the charging of two energy storage elements in order to power a motor of said thermoelectric watch.
