Abstract
Official abstract text for this publication.
The present disclosure provides an object recognition apparatus, which includes: an actuator unit configured to contact an object and generate vibrations and transmit them through objects based on the inherent characteristic of the object; and a sensor unit connected to the actuator unit to receive the vibration and generate a voltage signal.
First claim
Opening claim text (preview).
What is claimed is: 1. An object recognition apparatus, comprising: an actuator unit configured to contact an object and generate a vibration based on an inherent characteristic of the object and to transmit the vibration through the object; a sensor unit set aside from the actuator unit to receive the transmitted vibration through the object and generate a voltage signal; and a substrate film configured to fix an initial state of a piezoelectric film of the actuator unit and a piezoelectric film of the sensor unit. 2. The object recognition apparatus according to claim 1 , wherein the actuator unit includes the piezoelectric film, and wherein the piezoelectric film of the actuator unit includes: a piezoelectric member formed in a plate shape; and a conductive material disposed on one surface of the piezoelectric member and another surface of the piezoelectric member opposite to the one surface. 3. The object recognition apparatus according to claim 2 , wherein a shielding film configured to shield the piezoelectric film of the actuator unit from an external environment is installed on the piezoelectric film of the actuator unit. 4. The object recognition apparatus according to claim 2 , wherein one surface of the piezoelectric film of the actuator unit is grounded, a voltage source is connected to another surface of the piezoelectric film, and the voltage source applies voltage maintaining a sinusoidal difference between the one surface and the other surface of the piezoelectric film. 5. The object recognition apparatus according to claim 2 , wherein the sensor unit includes a piezoelectric film, and wherein the piezoelectric film of the sensor unit includes: a piezoelectric member formed in a plate shape; and a conductive material disposed on the one surface of the piezoelectric member and the other surface of the piezoelectric member. 6. The object recognition apparatus according to claim 5 , wherein a shielding film configured to shield the piezoelectric film of the sensor unit from an external environment is installed on the piezoelectric film of the sensor unit.
