Piezoresistive pressure sensors for various biomedical applications 2

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

3. Gastrointestinal monitoring: Piezoresistive pressure sensors can be used to measure pressure changes in the gastrointestinal tract and evaluate physiological processes such as gastrointestinal peristalsis and food passage speed. This is very helpful for diagnosing and treating gastrointestinal diseases.diode

4. Urine flow measurement: Piezoresistive pressure sensors can be used to measure urine flow, evaluate urine excretion function, and monitor changes in urine flow. This is very important for the diagnosis and treatment of urine related diseases.

5. Pressure ulcer prevention: Pressure resistant pressure sensors can be used on mattresses or seats to monitor the pressure distribution of body contact. By monitoring changes in pressure, one can adjust their position in a timely manner to prevent the occurrence of pressure ulcers.diode

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

1. Biocompatibility: Sensor materials need to meet biocompatibility requirements to ensure that they do not cause allergies or other adverse reactions when in contact with living organisms.diode
