ELECTRONIC APPARATUS COMPRISING PIEZOELECTRIC MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18376401 titled 'ELECTRONIC APPARATUS COMPRISING PIEZOELECTRIC MODULE
Simplified Explanation
An electronic apparatus described in the patent application consists of a housing and a piezoelectric module. The piezoelectric module has two regions: a first region that detects biometric information using ultrasonic waves and a second region that provides haptic feedback. The module includes a first electrode layer and a second electrode layer facing each other, with a piezoelectric layer positioned between them. In the first region, a portion of the piezoelectric layer vibrates at a first frequency band to emit ultrasonic waves, while in the second region, another portion of the piezoelectric layer vibrates at a second frequency band lower than the first frequency band.
- The electronic apparatus includes a piezoelectric module that can detect biometric information using ultrasonic waves and provide haptic feedback.
- The piezoelectric module consists of a housing, a first electrode layer, a second electrode layer, and a piezoelectric layer.
- The first region of the piezoelectric module is responsible for detecting biometric information using ultrasonic waves.
- The second region of the piezoelectric module provides haptic feedback.
- The piezoelectric layer vibrates at different frequency bands in each region to perform its respective functions.
Potential applications of this technology:
- Biometric authentication: The piezoelectric module can be used to detect biometric information such as fingerprints or palm prints using ultrasonic waves.
- Haptic feedback in electronic devices: The second region of the piezoelectric module can provide tactile feedback in devices like smartphones or gaming controllers.
Problems solved by this technology:
- Accurate biometric detection: The use of ultrasonic waves allows for more precise and reliable biometric authentication compared to other methods.
- Enhanced user experience: The haptic feedback provided by the piezoelectric module improves the user's interaction with electronic devices, making them more intuitive and immersive.
Benefits of this technology:
- Improved security: The use of ultrasonic waves for biometric detection enhances the security of authentication systems.
- Enhanced user interface: The haptic feedback adds a tactile dimension to the user interface, making it more engaging and intuitive.
- Compact design: The integration of the piezoelectric module into electronic devices allows for a compact and space-efficient design.
