Abstract
A thermoelectric watch includes a thermoelectric generator; a voltage booster connected to the thermoelectric generator, and 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 includes 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.
