SELF POWER GENERATOR

摘要

PURPOSE: A self power generator is provided to obtain an uniform piezoelectric element by using a graphene thin film having piezoelectric characteristics. CONSTITUTION: A graphene thin film(120) has a piezoelectric characteristic on a flexible printed circuit board(110). First and second electrodes(130, 140) are electrically connected to the graphene thin film. The first and second electrodes are engaged with each other in the graphene thin film. The plural first electrodes are electrically connected to each other through a first connection unit. The plural second electrodes are electrically connected to each other through a second connection unit. An insulating unit(150) is formed between the first and second electrodes.
