Piezoelectric/Electrostrictive Microphones TRIZ Cases
- Dishwasher Acoustic Drain Diagnostics Using Piezo Microphone
See how a piezo microphone and frequency-domain audio analysis diagnose dishwasher drain clogs,
- Piezoelectric Sound Energy Harvester With Force-Amplifying Pin
A large-head pressure pin concentrates sound-wave force onto a piezoelectric element, enabling compact harvesters to generate usable voltage.
- Raised-Electrode Laminated Piezoelectric Sheet for Uniform Signal Output
A raised electrode pattern improves signal uniformity across laminated piezoelectric sheets while supporting simpler large-scale production.
- Composite MEMS Microphone Carrier for Thin Packages and Larger Back Volume
A recessed composite carrier increases MEMS microphone back volume in a thin package while improving durability and reducing current leakage.
- Vehicle Textile Surfaces With Piezoelectric Fibers for Hidden Acoustic Pickup
Piezoelectric fibers woven into vehicle textiles capture acoustic signals without visible microphones, improving interior integration and user familiarity.
- Integrated Ultrasonic Sensor and Microphone for Compact Vehicle Sensing
A shared housing and acoustic channel combine ultrasonic sensing and sound pickup in one vehicle mount while saving space and protecting the microphone.
- Piezoelectric Membrane Integrity Indicator for Power-Free Leak Detection
Mechanical vibrations from membrane leaks power a piezoelectric LED indicator, enabling fast remote integrity checks without external power.
