The technology can be applied in:
- Touchscreen devices
- Interactive displays
- Wearable technology
Problems Solved
This technology addresses:
- Accurate touch detection
- Enhanced user experience
- Improved touch sensitivity
Benefits
The benefits of this technology include:
- Increased touch accuracy
- Redundant touch detection
- Enhanced durability of touch surfaces
Potential Commercial Applications
This technology can be utilized in:
- Smartphones and tablets

- Automotive touchscreens
Possible Prior Art
One possible prior art could be the use of piezoelectric transducers in medical devices for touch-sensitive applications.
What are the manufacturing considerations for integrating piezoelectric transducers into flexible circuits?
Manufacturing considerations may include the alignment and attachment of the transducers to the flexible circuit, ensuring proper electrical connections, and optimizing the shape and size of the circuit for the intended application.
How does the use of piezoelectric transducers impact the overall cost of touch-sensitive devices?
The use of piezoelectric transducers may increase the cost of touch-sensitive devices due to the additional components and manufacturing processes involved. However, the benefits of improved touch accuracy and sensitivity may justify the added cost for certain applications.
Original Abstract Submitted
examples of the disclosure are directed to the use of one or more piezoelectric (pe) transducers for detecting one or more touches on a surface. in some embodiments, the one or more pe transducers can complement a capacitive touch sensor array and provide a confirmation that a touch has in fact occurred, and can provide a secondary determination of touch location. in some examples, the one or more pe transducers can be formed on, or as part of, a flex circuit that is adhered to a housing or other structure to which the touch surface is affixed. the flex circuit can be formed as a strip upon which the one or more pe transducers are attached, and can be shaped and sized (optionally with a fold to create a tail for electrical connections) to adhere to an inner or outer surface of the housing.
