Abstract:
PURPOSE: An electrical energy generator and an electrical energy storage apparatus including the same are provided to uniformly supply pressure to a plurality of nano piezoelectric devices using a carbon nano tube sheet, thereby preventing damage to the nano piezoelectric device due to excessive pressure. CONSTITUTION: A nano piezoelectric device(40) is formed on a first electrode(30). The nano piezoelectric device generates electricity using a piezoelectric effect. A second electrode is formed on the upper part of the nano piezoelectric device. A carbon nano tube sheet(50) is formed between the second electrode and the nano piezoelectric device. The carbon nano tube sheet is fixed on an upper substrate(60).
