Impedence TRIZ Cases
- Ultrasonic Sensor Frequency Tuning for Automatic Deicing
Resonance-tuned ultrasonic waves remove frozen precipitation from sensor surfaces, restoring reliable sensing without manual deicing.
- Acoustic Sensor Nanowire Structure for CMP Endpoint Detection
Slurry scattering disrupts optical CMP endpoint monitoring; varying-height nanowires convert acoustic waves into electrical signals for reliable detection.
- Acoustic Impedance Compensation via Hilbert Transform
Estimating acoustic mass and characteristic impedance using Hilbert transforms minimizes errors caused by evanescent modes in unknown loads.
- Acoustic Impedance Sensor Using Piezoelectric Chip
Replacing capillary tubes with a direct-drive loudspeaker eliminates signal attenuation and simplifies calibration across wide frequency ranges.
- Vibration Sensor Carrier Coupling Quality Assessment
A vibration sensor carrier evaluates electromechanical impedance to verify physical contact quality.
- Transducer Calibration via Spatial Frequency Domain Smoothing
Spatial frequency domain smoothing technology processes transducer signals to suppress reflection wave interference, expanding low-frequency measurement limits.
