Application Examples of Electret Electrostatic Induction Watch (World's First)

Citizen Watch Co., Ltd. developed the world's first "electrostatic induction watch" that has two functions, "electrostatic induction power generation" and "electrostatic induction motor", using the phenomenon of static electricity, and released it from ACCUTRON, its affiliated American brand.
TOHO KASEI's fluoropolymer film laminated products are used in this "electrostatic induction power generation" and "electrostatic induction motor".

"Electrostatic induction" is a phenomenon in which, when the electrically charged object is brought close to the conductor (a material that conducts electricity), an electric charge of a reverse polarity from the electrically charged object is attracted to the surface of the conductor.
Electric power is generated through electrostatic induction by two rotors located at 5 o'clock/7 o'clock rotating at high speed with the arms swung by the power generating turbine.
This power is stored in a secondary battery and used to power the rotor, located at 10 o'clock, operating as an electrostatic induction motor that drives the second hand.
