Characteristics of Thin-Film Pressure Sensors

Thin-film pressure sensors are based on thin-film materials and possess the following characteristics:

  1. High Sensitivity: Capable of detecting minute pressure changes, ideal for precise medical monitoring.
  2. Lightweight and Flexible: Easily integrated into various medical devices without compromising patient comfort.
  3. High Precision: Provides reliable pressure data, ensuring accurate medical monitoring and diagnostics.
  4. Durability: Long lifespan, adaptable to various complex medical environments.

Application Scenarios

1. Position Monitoring

Thin-film pressure sensors can be used in hospital beds and wheelchairs for position monitoring systems. By continuously monitoring the patient’s position, caregivers can adjust the patient’s posture in a timely manner to prevent bedsores and improve the quality of care.

2. Respiratory Monitoring

In respiratory monitoring devices, thin-film pressure sensors can detect the patient’s breathing rate and depth. Accurate monitoring of respiratory parameters allows doctors to better assess respiratory function and detect abnormalities promptly for timely intervention.

3. Blood Pressure Monitoring

Thin-film pressure sensors are widely used in non-invasive blood pressure monitoring devices. Their high sensitivity and precision provide accurate blood pressure readings, enabling doctors and patients to monitor blood pressure changes and manage health effectively.

4. Post-Operative Rehabilitation Monitoring

During post-operative rehabilitation, thin-film pressure sensors can monitor the patient’s activity and recovery progress. For instance, sensors embedded in rehabilitation training equipment can record the patient’s pressure distribution and movement patterns in real time, assisting rehabilitation doctors in developing scientific recovery plans.

Technical Advantages

Real-Time Monitoring: Thin-film pressure sensors can record pressure changes and physiological parameters in real time, providing immediate data support to assist medical personnel in making timely decisions.

Intelligent Analysis: By combining big data and artificial intelligence technologies, thin-film pressure sensors can deeply analyze the collected data, offering personalized medical advice and risk alerts.

Data Visualization: Through the display interfaces of medical monitoring devices, doctors and patients can view pressure data and historical records intuitively, understanding health status and treatment progress.
