Piezoresistive pressure sensors for various biomedical applications 2

2. Respiratory Monitoring: Piezoresistive pressure sensors can be embedded in ventilators, masks, or catheters to monitor changes in airway pressure during respiration. This is crucial for assessing respiratory function and evaluating the effectiveness of respiratory support.diode

3. Gastrointestinal Monitoring: Piezoresistive pressure sensors can be used to measure pressure changes within the gastrointestinal tract, aiding in the assessment of physiological processes such as gastrointestinal motility and food transit speed. This is highly beneficial for the diagnosis and treatment of gastrointestinal disorders.diode

4. Urine flow measurement: Piezoresistive pressure sensors can be used to measure urine flow, aiding in the assessment of urinary excretion function and monitoring changes in urine flow. This is crucial for the diagnosis and treatment of urine-related diseases.diode

5. Pressure Sore Prevention: Resistive pressure sensors can be integrated into mattresses or seating systems to monitor the distribution of pressure from body contact. By tracking pressure variations, timely adjustments to body position can be made to prevent the occurrence of pressure sores.diode

It should be noted that the use of piezoresistive pressure sensors in biomedical applications requires consideration of the following factors:diode

1. Biocompatibility: The sensor material must meet biocompatibility requirements to ensure it does not cause allergies or other adverse reactions when in contact with biological tissues.diode
