REFLECTOR FOR AN ACOUSTOPHORETIC DEVICE |
| 摘要 |
An apparatus includes a flow chamber having at least one inlet and at least one outlet. At least one ultrasonic transducer is located on a wall of the flow chamber, which operates to create a multi-dimensional acoustic standing wave in the flow chamber. A reflector is located on the wall on the opposite side of the flow chamber from the at least one ultrasonic transducer. The reflector is formed from a thin structure that provides a pressure release boundary, such as a plastic film/air interface. |

1. An apparatus, comprising:
a flow chamber having at least one inlet and at least one outlet; at least one ultrasonic transducer located on a wall of the flow chamber, the transducer including a piezoelectric material driven by a voltage signal to create a multi-dimensional acoustic standing wave in the flow chamber; and a thin structure located on a wall opposite the at least one ultrasonic transducer, the thin structure providing a pressure release boundary that acts as a reflector. |
