Laparoscopic surgery, a minimally invasive technique involving small abdominal incisions, employs specialised tools like forceps, scissors, and probes. Despite its benefits, the challenge of reduced tactile sensation hinders precise tissue manipulation. Addressing this, Associate Professor Benjamin Tee and his research team, including Dr Wen Cheng and PhD student Wang Xingyu from iHealthtech, introduced “eAir.” This ultrahigh-sensitive tactile sensing innovation utilises minute air gaps as aero-elastic pressure sensors, accurately measuring pressure between surgical tools and tissue, thus enhancing tactile feedback. This innovative technology promises error reduction and broader applications in surgical robots due to its responsiveness to pressure changes, even within liquid environments.
The team’s findings were recently published in the prestigious scientific journal Nature Materials on August 17, 2023.
