Area of Science:

  • Biomedical Engineering
  • Sensor Technology
  • Medical Devices

Background:

  • Next-generation automated intravenous regional anaesthesia (IVRA) systems require enhanced safety features.
  • Minimally intrusive pressure sensors are crucial for monitoring IVRA procedures.
  • Existing sensors may not adequately address specific IVRA-related artifacts.

Purpose of the Study:

  • To fabricate and test a novel, minimally intrusive biomedical interface pressure sensor.
  • To evaluate the sensor's suitability for integration into automated IVRA systems.
  • To assess the sensor's capability in detecting potential IVRA hazard conditions.

Main Methods:

  • Fabrication of a compact (2 mm high, 10 mm diameter) pressure sensor using a structured elastomer within a parallel plate capacitor.
