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.
Claims16
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, characterized in that wherein the watch further includes at least one capacitor connected to said energy management circuit coupled to a load configured to:
- undergo a variation of load when said output of said energy management circuit changes either from the first state to the second state, or from the second state to the first state,
- supply current to said load when said capacitor undergoes said variation of load, said load being configured to emit a signal detectable by a measuring apparatus when said current flows therethrough.
A thermoelectric watch comprising:
- a thermoelectric generator,
