New piezoresistive sensors in forceps can detect simulated organ tissue abnormalities. This technology aids in identifying phantom tumors during minimal access surgery, improving diagnostic accuracy.

Area of Science:

  • Biomedical Engineering
  • Surgical Technology
  • Materials Science

Background:

  • Minimal access surgery requires advanced tools for accurate tissue assessment.
  • Detecting subtle abnormalities in organ tissue remains a challenge.
  • Piezoresistive materials offer potential for sensitive force and pressure sensing.

Purpose of the Study:

  • To develop and evaluate a novel sensor-based approach for detecting organ tissue abnormalities.
  • To assess the feasibility of integrating piezoresistive sensors into surgical forceps.
  • To visualize and interpret data from simulated diseased tissue.

Main Methods:

  • Development of prototype piezoresistive sensors.
  • Assembly of sensors into a forceps configuration.
