Researchers at the University of Cambridge, UK, have developed a smart surgical aid with sensors for hip replacement surgery . Known as the "trial liner," this device features flexible and thin sensors powered by advanced microfluidic technology (Image 1).

The embedded sensors measure forces passing through the joint, which assists surgeons in evaluating and balancing the soft tissues.
After making the measurements and marking the optimal position for the implant, surgeons can remove the trial liner and proceed with surgeries. Unlike traditional methods, which rely on a surgeonβs intuition and anatomical landmarks, this smart trial liner provides real-time measurements during surgery. The prototype has undergone extensive laboratory validation.β¦
