Stethoscope TRIZ Cases
- Implantable Diaphragm Stimulator for Cardiac Optimization
An implantable device scans stimulation parameters to optimize diaphragmatic therapy.
- Wearable Acoustic Sensor System for Multi-Organ Health Monitoring
Segmented acoustic sensors guide organ-specific sounds to processors, enabling continuous multi-organ health monitoring while managing device complexity.
- Cough Analysis System for Respiratory Illness Detection
Automated acoustic cough analysis replaces subjective clinical judgment with objective signal processing to detect severe respiratory illnesses early.
- Phased Array Acoustic Sensors for Steam Pop Detection in Catheter Ablation
A phased array of acoustic sensors derives a focused phase profile to detect faint steam pops, preventing tissue damage from background noise masking.
- Biological Sound Measuring Device Sensitivity Calibration
Controller generates test sound to measure sensitivity ratio between internal and external microphones for accurate biological sound detection.
- Wearable Ultrasound Transducer Arrays for Continuous Blood Pressure Monitoring
Dual ultrasound transducer arrays measure pulse transit time across the brachial artery to estimate blood pressure in a wearable device.
