ULTRASONIC TRANSDUCER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240315138 titled 'ULTRASONIC TRANSDUCER

The abstract of the patent application describes an ultrasonic transducer consisting of a case, a piezoelectric element, and a filler. The case has a cylindrical shape with a bottom portion and a side wall portion, with the piezoelectric element attached to the bottom portion. The filler, which is a foamed silicone resin with a closed-cell foam structure, fills the case and covers the piezoelectric element, sealing a cavity in the side wall portion.

  • The ultrasonic transducer includes a case with a bottomed cylindrical shape.
  • A piezoelectric element is attached to the bottom portion of the case.
  • The filler, made of foamed silicone resin, fills the case and covers the piezoelectric element.
  • A cavity in the side wall portion is sealed with the filler.
  • The filler has a closed-cell foam structure.

Potential Applications: - Medical imaging devices - Non-destructive testing equipment - Underwater sonar systems

Problems Solved: - Protection of the piezoelectric element - Sealing of the cavity in the case - Enhanced performance of the ultrasonic transducer

Benefits: - Improved durability and longevity - Increased efficiency in ultrasonic applications - Enhanced signal quality

Commercial Applications: Title: "Innovative Ultrasonic Transducer for Various Industries" This technology can be utilized in medical imaging, industrial testing, and marine navigation systems, offering improved performance and reliability in a wide range of commercial applications.

Questions about Ultrasonic Transducer: 1. How does the foamed silicone resin filler contribute to the functionality of the ultrasonic transducer? - The foamed silicone resin filler provides protection to the piezoelectric element and seals the cavity in the case, enhancing the overall performance and durability of the transducer.

2. What are the potential advantages of using a closed-cell foam structure in the filler material? - The closed-cell foam structure ensures better insulation and protection for the piezoelectric element, leading to improved efficiency and longevity of the ultrasonic transducer.


Original Abstract Submitted

an ultrasonic transducer includes a case, a piezoelectric element, and a filler. the case has a bottomed cylindrical shape including a bottom portion and a side wall portion. the piezoelectric element is attached to the bottom portion of the case. the filler fills at least a portion in the case adjacent to or in a vicinity of the bottom portion and covers the piezoelectric element. a cavity is provided in a portion of the side wall portion adjacent to or in a vicinity of the bottom portion. the filler includes a foamed silicone resin with a closed-cell foam structure. the cavity is sealed with the filler.
