Stethoscope TRIZ Cases
- Wearable Pleural Effusion Screening via Acoustic Percussion
A wearable garment integrates percussion devices and sensors to capture respiratory sound data for pleural effusion detection.
- Acoustic Lung Imaging via Smartphone Thermal Conversion
An acoustic sensing unit captures respiratory signals and converts them into real-time thermal images for immediate visualization.
- Sensor Membrane Polarity Cancellation for Signal Noise Reduction
Opposing sensor membranes cancel unwanted vibration signals to improve measurement precision without increasing device complexity.
- Expandable Earpiece Sealing Mechanism for Acoustic Isolation
Inflatable bladders adapt to individual ear anatomy, resolving the trade-off between manufacturing complexity and effective sound isolation.
- Blood Pressure Monitor With Snore Detection For Sleep Accuracy
A blood pressure monitor integrates a microphone to detect body sounds during measurement.
- Cardiac Pacing Control via Electromechanical Timing
A cardiac device detects electromechanical timing to control pacing therapy.
- Portable Stethoscope Sanitizer Using UV-C Radiation and Reflective Cavity
A portable stethoscope sanitation device uses a UV-C emitter and reflective cavity to kill pathogens on patient-facing surfaces.
