PIEZOELECTRIC ELEMENT, PIEZOELECTRIC FILM, AND MANUFACTURING METHOD FOR PIEZOELECTRIC FILM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18464273 titled 'PIEZOELECTRIC ELEMENT, PIEZOELECTRIC FILM, AND MANUFACTURING METHOD FOR PIEZOELECTRIC FILM

Simplified Explanation

The patent application describes a piezoelectric film made of a perovskite-type oxide that exhibits a unique current-voltage profile when a voltage is applied. The profile shows two maximum values and is obtained by sweeping the voltage from -40 V to +40 V at a rate of 10 kV/cm·sec while the film is sandwiched between two electrode layers.

  • The piezoelectric film is made of a perovskite-type oxide.
  • The current-voltage profile of the film has two maximal values.
  • The profile is obtained by applying a voltage sweep from -40 V to +40 V at a rate of 10 kV/cm·sec.
  • The film is sandwiched between two electrode layers.

Potential Applications

  • Energy harvesting: The unique current-voltage profile of the piezoelectric film can be utilized to convert mechanical energy into electrical energy, making it suitable for energy harvesting applications.
  • Sensing and actuation: The film's piezoelectric properties can be utilized for sensing and actuation purposes, such as in pressure sensors or actuators.
  • Electronics: The film's unique characteristics can be integrated into electronic devices, such as transistors or memory devices, to enhance their performance.

Problems Solved

Original Abstract Submitted

The piezoelectric film is a piezoelectric film containing a perovskite-type oxide as a main component, in which a current-voltage profile showing a relationship between a voltage and a current that flows in a case where the voltage is applied has two maximal values, where the current-voltage profile is acquired in a case where the voltage is sweep-applied from −40 V to +40 V at a first change rate of 10 kV/cm·sec while the piezoelectric film is sandwiched between a pair of electrode layers.
